Latest News:

Bitwise has released (12/7/2020) their OS/2 port of Apache OpenOffice 4.1.8. Bitwise took over OpenOffice development from Mensys, but the primary developer on the project remains the same; they allow you to purchase "development units" in their online shop, as a means of donating to the ongoing development, and being offered the download link. Bug reports can be filed in the OpenOffice Bugzilla, and presumably the OS/2 source code continues to be available in the Subversion repository. There were plans for future updates to the WPS integration package, but the previous version from Mensys should continue to function; it extends the WPS data file class to recognize document files, has integrated support for WPS-Wizard hint and folder info area, and provides Rexx hooks for reading document properties. From VOICE News.

ArcaOS 5.0.6 has been released (8/31/2020). This refreshed install contains various updates, including initial support for USB3, and the ability to install from a bootable USB stick. The big new feature in 5.0.4 was the ability to upgrade from a previous 5.0.x install, making it easy to apply all the latest updates. You may also like to read my earlier mini review.

VLC media player version 3.0.11 has been ported (7/18/2020) to OS/2. This is a highly portable multimedia player and multimedia framework capable of reading most audio and video formats (MPEG-2, MPEG-4, H.264, DivX, MPEG-1, MP3, OGG, AAC) as well as DVDs, Audio CDs, VCDs, and various streaming protocols.

The UniAud sound drivers have been refreshed (5/6/2020). This is based on the GPL ALSA Project from Linux and provides drivers for various sound chipsets, including HDA, AC97, and PCI cards. Note that the cause of repeating system sounds has been found to be a bug in IBM's SND.DLL, and there is a workaround available. For what it's worth, this project has stagnated for quite a while now; ALSA 1.0.24 is from early 2011, while the current upstream version is 1.2.3. Paul Smedley has been making various test builds of newer versions, if you want to help testing them out (just be aware of the potential for crashes during boot).

XWorkplace version 1.0.13 has been released (2/1/2020); recent features include reboot options via boot manager integration, more display options for the Pulse widget, an ACPI-based CPU temperature, and an improved version of the split folder view. It includes all the features of XFolder 0.85, virtual desktops using xPager (formerly PageMage), a replacement for WarpCenter (XCenter) with lots of widgets, a trash can, most of the NPSWPS and WarpEnhancer features, object hotkeys, lots of new settings pages, and more. XWorkplace is an open source project at From VOICE News.

Esther Schindler has an Ars Technica article looking back on computer user groups; some may remember the Phoenix OS/2 Society was a big group a while back.

Justin Coleman mocked up some images of how he imagined an updated OS/2 might look: System settings, taskbar menu, apps submenu, shutdown menu, and Windows 10 in a VM.

Warpstock 2020 will be held on-line on Saturday, November 7; registration will not be required for this virtual conference. Attendance will be via YouTube stream, and questions may be posed via YouTube Chat as well as IRC. There will be an early session for North America and Europe, and a late one for North America and Australia/Asia. Warpstock 2019 was held November 8-10, in Orlando, Florida; you can see some picture galleries and YouTube videos from the event. Thanks to Andy Willis and VOICE News for the info.

Warpstock Europe 2020 was held as a vritual event on May 16-17; there are a few YouTube videos available. The 20th Anniversary 2019 event was held in the Netherlands on May 18-19; you can see some of the presentations in this YouTube playlist.

Sigurd Fastenrath created a YouTube video celebrating the 25th Anniversary of IBM OS/2 Warp, showing it running on modern Hardware. He has previously been successful in getting OS/2 running on the 25th Anniversary ThinkPad.

Bitwise has released (10/23/2019) Qt 5.13.1 for OS/2 beta 1 (although the netlabs-rel repository is currently still offering the earlier 5.11 beta); the README lists some of the current limitations. Once complete, they are looking at porting a couple Qt-based browsers: Falkon (formerly Qupzilla), and Otter. Roderick Klein posted an update on the VOICE browser fundraising campaign, indicating that funding is still required. You can see the original Qt5 roadmap, which projected a full year of work on porting Qt itself, and then another 6 months on porting QtWebEngine components. If you want to help with funding, you can contribute to Bitwise directly, via Patreon, or to the VOICE campaign. From VOICE News.

On the ArcaOS bug tracker, there is a "vio" driver that allows DOS and WinOS2 sessions to work on some hardware where it otherwise fails, such as the ThinkPad X250. It also causes hangs on some hardware, so take care in testing.

Arca Noae has posted a couple progress reports on what they have been working on. An updated Removable Media Monitor widget for XCenter is coming, which will handle media changes better. Handling transparent switching of audio output when a USB audio device is plugged in or unplugged is in testing. Better Brother laser printer support is coming for CUPS. USB3 support is getting closer.

Arca Noae continues to work towards supporting UEFI, for booting on systems without legacy BIOS support; Intel has previously announced that legacy support would be removed from their platforms in 2020. In this video a proof of concept is demonstrated that allows ArcaOS to boot from UEFI-only systems. TechRepublic took note, and wrote an article about the coming support. From VOICE News and OS2World.

Lars Erdmann has announced that he is seeking a new maintainer for the OS/2 USB stack.

This TechRadar article mentions ArcaOS and OS/2 in their list of the best alternative operating systems. From OS2World.

ColourManager/2 and MouseSmart have been released as open source software by the author. ColourManager/2 allows you to adjust the color scheme used on your desktop, and MouseSmart is a program that helps improve the way the mouse cursor moves within OS/2. From OS2World.

Bryan Lunduke posted a YouTube video entitled: IBM OS/2 Warp 4 - Best OS... ever? From OS2World.

Dave Yeo has released "SUa2" builds of Firefox 45.9.0 (6/3/2019), Thunderbird 45.8.0 (6/1/2019), and SeaMonkey 2.42.9 (6/2/2019). These "Security Update" builds have security fixes ported from tenfourfox, a Firefox fork for PowerPC Macs that was forked from 45ESR; there are around 100 security issues patched. Note that there are additional external dependencies required; see my Warpzilla Tips page for more information, as well as mozsupport and mozmedia packages. Note that the SeaMonkey project skipped from version 2.40 to 2.46 on other platforms. Reports on earlier builds suggested that disabling Chatzilla may prevent some heavy CPU usage.

Tedium has a nice article on the history of OS/2 usage in the New York subway.

Arca Noae has split their roadmaps into General, ArcaOS, Drivers, Software, and Advocacy & Events. ArcaOS 5.0.4 is in beta, which will include Samba 4.9, and the ability to update from earlier 5.0.x releases. They posted a progress report, indicating updates to Panorama are coming, and ACPI and AHCI had recent updates. They are testing USB 3 support, as well as investigating booting on UEFI systems. A new LVM GUI is in the works.

Bitwise has forked kLIBC into LIBC Next. A fork became necessary because the kLIBC project is not actively maintained. LIBC Next is fully backward compatible with the kLIBC library and may be used as a drop-in replacement. From VOICE News.

The OS/2 Guest Additions for VirtualBox were updated as part of the VirtualBox 6.0.6 update (for other platforms). If you are running OS/2 on a Virtualbox VM, use "Devices - Insert Guest Additions CD Image...", then check the OS/2 CD drive inside the /OS2 directory. From OS2World.

OS2World recently celebrated its 19th year online. It continues to be a great resource for the community.

There was a Presentation Manager Programming Workshop held on Saturday, November 3, 2018 in the Netherlands, by the hcc eCS User Group. The documentation used is available online on the EDM/2 Wiki. From VOICE News.

Warpstock 2018 was held in Calgary, Alberta, Canada, September 14-16. You can see the schedule, it was streamed live on YouTube, and the presentation materials are also online. Arca Noae announced that the first beta for 5.0.4, which will finally include an update option, is already in testing. Version 5.1 is scheduled for release in 2019, with a host of new features planned, including NLVs for several popular languages.

The presentation files from Warpstock Europe 2018 are available online; of particular interest are Lewis Rosenthal on the ArcaOS Roadmap where some details about 5.0.3 and 5.1 are shared, and Silvan Scherrer on Bitwise projects.

VOICE News posts are now posted to Twitter, in addition to the mailing list and newsgroup feed. In other VOICE news, they are testing a remote support tool, which is essentially VNC over SSH.

The bitwiseworks Firefox fork has released (5/20/2018) a "GA2" build, still based on Gecko 45.9.0esr. Note that 45esr was long ago obsoleted by 52esr, which in turn was obsoleted by 60esr, with 45esr not getting security updates since April 2017. This build has more bugfixes, but the "GA" releases have generally been worse than the earlier "beta" releases. Also, native printing support other than Postscript was dropped, although printing to PDF is possible. There are several additional external dependencies required now; see the README file for more details. Note that Bitwise has abandoned the ZIP packaging for an RPM package (which is not publicly available), and instead offers an archive based on the RPM package. It is unclear if there will be any releases based on 52esr, but that will be the end of the road, as newer versions require the Rust compiler, which is unlikely to be ported to OS/2. Note that the SeaMonkey project is also undecided on how it will proceed beyond 52esr (on all platforms), as Mozilla long ago stopped caring about anything other than Firefox. You can donate to bitwise projects by buying sponsor units via their online shop.

Ryan C. Gordon, of fame, spent a bit of time hacking on "'2ine,' pronounced 'twine,' which emulates OS/2 binaries in the same way that Wine emulates Windows binaries." He managed to get quite a bit of command line OS/2 apps running on Linux (including compilers), as well as some bare bones Presentation Manager windowing support (just enough to draw a rectangle on the screen). It's unlikely that he will spend any more on it, but the source code is available for anyone else to play around with.

There is a nice 45 minute YouTube video celebrating 30 years of OS/2. It goes over some history, as well as how it can be used today.

VOICE has been organizing IRC chats (VOICE SpeakUp) with developers and organizations supporting the OS/2 community. The first two events were with Arca Noae: Saturday, February 17th, and Sunday, February 25th. The third was with Bitwiseworks, the company that works on ports like OpenOffice and Fiefox, on March 3rd. For these events, you can use an IRC client, or the webchat channel #os2voice. From VOICE News.

Lars Erdmann and Wim Brul continue to improve the USB drivers; the latest features are support for 24-bit audio, and sample frequencies greater than 64KHz, on USB audio devices (speakers and headphones) that support such features in hardware. Hopefully, someone can take that work and extend it to UniAud as well. In other USB news, Arca Noae has begun converting some of the USB code to 32-bit, in anticipation of USB3 support, and Lars has expressed concern that the driver interfaces will become incompatible with third-party USB driver work, such as the work that he and Wim continue to invest.

Last September, Adrian Gschwend wrote a retrospective article for the 20th anniversary of He also did a remote presentation for Warpstock 2017 in Canada. He would like to replace the aging server, and is looking to raise $3000 in sponsorships.

EDM/2 (Electronic Developer Magazine/2) has had another batch of updates to the wiki; as a wiki, it is possible for everyone to add or edit articles. From VOICE News.

The experimental OS/4 kernel now has support for AVX instructions, as found in newer CPUs. This means potentially better performance in software that supports it, such as ffmpeg, firefox, and others.

There is now an option to convert your Arca Noae driver subscription to an ArcaOS subscription. Arca Noae has made several updates available, which can be downloaded from the order page on their site (the same page that provides the ISO download).

I have updated my ArcaOS article a few times; part 3 includes a couple fun hacks for SNAP Graphics. Arca Noae is looking into adding accelerated hardware support for newer Intel graphics chipsets. They are still working on having a bootable USB installation, which may make it into a 5.0.x point release. It's likely there will be both 5.0.2 and 5.0.3 prior to the 5.1 release, which is planned to have additional NLS language support included. They are also exploring the feasibility of a VDD for UniAud, to provide sound support in DOS and WinOS2 sessions.

A new release of Odin32 may be out soon; there's been some work recently on getting version 0.9.0 prepared. Odin32 can be used to run and/or build Win32 applications for OS/2, and is based on WINE and IBM's Open32.

VOICE has released their 2016 financial report. They are currently accepting applications for those wanting to become a VOICE board member, with the President and two board positions up for re-election. Roderick Klein is running for re-election as President, Bjorn Rietdijk is running for re-election as Board member, and Stuart Updike has stepped down. Applications should be sent via email before August 12th to the Vice President, Neil Waldhauer, describing why you want to join the VOICE board. The current board members will then vote. From VOICE News.

ArcaOS 5.0 (code name Blue Lion) has been released (5/15/2017), marking the first OS/2 update since eComStation 2.1 in 2011. There are some official screenshots to provide a quick overview. There are two levels of pricing: a personal license is $129, with an intro price of $99 for the first 90 days of release, while a commercial license is $229. The former includes 6 months of support and maintenance updates, while the latter includes one year. If you have an existing software subscription, check the details on your available options; of note is that ArcaOS 5.1 is already in the planning stages. An earlier announcement detailed some of what to expect in this 5.0 release: XWorkplace with ArcaOS branding and exclusive features (such as a new Removable Device widget); new apps including DVD Tools, Archive Tool, Dynamic Icons, ArcaBar, Lucide Document Viewer, and much more; new network filesystem connectivity (Samba 4.5); updated kernel, with fixes and enhancements to better handle modern memory-hungry apps; new loader, allowing use of RAM above 4GB as a RAM disk; brand new installer; updated SNAP accelerated video driver; and more. The OS2World forum has lots of discussion about getting ArcaOS installed on various hardware, and Lewis Rosenthal did a video interview with Bryan Lunduke on YouTube (skip the first 7 minutes or so of the video to get past the unrelated bits); which was followed by a video review.

Roderick Klein wrote an article describing how VOICE has been spending donations, as well as where it plans to invest going forward. Most money came from PMMail licenses, and it has been spent on,, funding BitWise Works to port Qt 5.5, hardware for webcam drivers, improvements to XWorkplace, and Warpstock events. There are plans to host an RPM repository, get the VOICE Newsletter going again, and perhaps run a YouTube channel. From VOICE News.

A year after the open letter for the Apache Foundation to acknowledge that OpenOffice is dead, there is discussion within the project to retire it, due to a lack of developers. The IBM Lotus Symphony team quit working on the project years ago, and it has been mostly abandoned for some time. Unfortunately, the OS/2 support was removed from LibreOffice source code long ago.

The first issue of OS/2 Lab Notes has been made freely available as a PDF file. Printed issues are available for purchase; licensed users of PAF and/or OWPZip are entitled to free issues. From VOICE News.

Lars Erdmann gave an interview about USB driver development at Warpstock Europe.

Lewis Rosenthal's presentation at Warpstock Europe was covered in a TechRepublic article, where it was revealed that the new OS/2 distribution code named Blue Lion would be called ArcaOS 5.0, and is expected to be released before the end of 2016. Version 5.1 will provide additional language support, and is tentatively planned for a 2017 release. There will be a Commercial Edition with 12 months of updates and priority support, and a Personal Edition with 6 months of updates and support, offered at a lower price; pricing is not yet finalized. From OS2World and VOICE News.

bww and Arca Noae are actively seeking one or more developers to work on the Eclipse SWT project (also used used by SmartSVN and SmartGit) and ultimately, the next OpenJDK build. This is funded development work, while the end product will remain freely available to all. Previous efforts included improving the Odin32 library to support needed functionality; presumably, that would still be a part of this project. Thanks to Lewis Rosenthal for the info.

The third annual OS/2 User Meeting in Cologne, Germany was held at the end of November, and there are some pictures and discussion available on Herwig Bauernfeind of Bitwise discussed their current and future projects: Firefox 38, Virtualbox 5 (in early alpha), updated Java, SWT and Eclipse, Samba 3.6, Injoy Firewall 5 (with a new Qt GUI), OpenOffice 4.1.2, and Qt5; Flash plugin support has been discontinued. The fourth annual event is already planned for Saturday, the 26th of November 2015, at the same location.

Arca Noae has posted their Blue Lion announcement and some FAQs, and there was some nice press coverage on TechRepublic, The Register, and Network World.

Lewis Rosenthal announced at Warpstock that Arca Noae is now licensed by IBM to create a new OS/2 distribution; it is currently codenamed "Blue Lion" and has a tentative release of Q3 2016. It will be based on OS/2 Warp 4.52 (MCP2) and the SMP kernel, with a new installer which does not require floppies or optical media (USB and possibly network installs), the Arca Noae driver updates including ACPI, USB, and MultiMac, and an updated version of SNAP Graphics. Lewis made it clear that there is no agreement between Arca Noae and XEU (formerly Mensys), and they intend to be a better OS/2 distribution than eComstation. Note that eComstation has been effectively dead since December 2013, despite some vague promises earlier this year that 2.2 would finally be released in October 2015.

Joachim Benjamins, formerly of Mensys and now XEU, came out of hiding to report on bugfixes that will be rolled into eCS 2.2, which is now expected in October. There is a healthy amount of skepticism in the forum, since there has been no progress since December 2013, and the bugfixes listed were done by others and have been available for quite some time already.

Arca Noae has licensed the SNAP Graphics for OS/2 source code from Alt Richmond Inc., the company that bought the SciTech SNAP technology several years ago. Mensys previously licensed it as well, but never utilized it in any way (at least, no fixes or updates were ever released publicly). Arca Noae hopes to add support for additional hardware, starting with newer Intel graphics chipsets. From VOICE News.

Martin Iturbide continues on his quest to get unmaintained OS/2 programs to be released as open source; he has created over 1500 public repositories of OS/2 open source projects on GitHub, created a wiki index for them, and published an EDM/2 article discussing how to use Git on OS/2. He has gone through the Hobbes archives, extracting the available source code, and making it easily accessible. He welcomes assistance in uploading more source to github, and any other suggestions, and will gladly provide repository administration rights to anyone interested. From OS2World.

Arca Noae has posted an informative FAQ about the company, licensing, drivers and software subscription, and more. They have also fleshed out their About page, detailing who is involved, and some of their previous OS/2 involvement. From VOICE News.

Arca Noae has announced their membership in the UEFI Forum. The UEFI (Unified Extensible Firmware Interface) specification defines a new model for the interface between operating systems and platform firmware, and is intended to replace the legacy BIOS. Arca Noae is looking into how this new technology can be supported under OS/2 in the future. From VOICE News.

Arca Noae recently acquired the remaining assets of Serenity Systems International, which was primarily its domain name. There was no change in status for eComstation, which continues to be an IBM licensee via XEU (formerly Mensys). From VOICE News.

This YouTube video shows OS/2 running on some recent hardware with touch screens, with some rudimentary software enabling a touch interface. The hardware includes a Sony laptop, a Samsung tablet, and a Lenovo laptop / tablet convertible.

Greggory Shaw reports that ownCloud version 7 runs well on the OS/2 ports of Apache and PHP (with the zip and iconv extensions); you can use SQLite as the database if you are the only user, or MySQL to support multiple users. He says that the native clients for Windows and Linux are fast and easy to setup, and the web interface can be used for all platforms. He uses Samba on eCS to access the ownCloud directories, while WebDAV can also be used via Netdrive.

Arca Noae has updated the roadmap of their product development; short term projects include a graphical package management utility, CUPS printer package, and new network drivers, while longer term will be UniAud updates, and further out will be investigation into SATA RAID and SAS controllers, non-LVM USB disk support, USB3 support, booting from a GPT partition, and overcoming the current 2TB hard disk size limitation. They are soliciting feedback on what users would like to see next, and have made available both personal and commercial editions of their software subscription package. Already available as part of the subscription are ACPI, USB, and MultiMac updates.

The OS/2 Shareware BBS collection of files is now hosted on; note that access is limited if you are not browsing on OS/2. This is the entire collection, accumulated over the period of March 1990 through August 2006.

Elmar Stellnberger reports that Mark Harvey's 20-year-old MultiUser program for giving different users different desktops continues to work well, and can be used in conjunction with the Security/2 sses package from Nickk. In addition to Hobbes, the software is available from Elmar's site, which also offers collections of icons and fonts.

The QSINIT loader is a replacement for OS2LDR; it allows 3.5GB of RAM to be used on certain systems where OS2LDR prevents using more than 512MB due to "memory holes". It also allows using memory above 4GB as a RAM disk, which otherwise is useless on a 32-bit operating system that does not support PAE (such as OS/2). It is now fully compatible with the official ACPI drivers, and has lots of other features, including PXE support, VESA video support, disk editor, reading, writing and formatting drives in FAT32 or FAT16, general partition managing capabilities, including GPT partition support, LVM support, general boot manager features, and more. The source code is also available. From OS2World.

Sander Nyman has graciously contributed more of his fine writing to stoke the fires of wild rumor and gossip:

Some of you may already have heard the exciting news that Menso de Jong, the founder of Mensys will attend Warpstock to speak on the future of eCS.

More information has become available from a source regarding the Mensys presentation. The following are some of the possible details as we currently understand them.

Because of the extreme rarity, and highly secretive nature of all Mensys discussions regarding "The future of eCS", all attendees will be required to wear blindfolds throughout the presentation. After careful consideration, the third movement of Frederic Chopin's Piano Sonata No.2 was chosen as the perfect accompaniment to set the mood for the presentation and to highlight eComStation's new multimedia platform, codenamed "Helen Keller".

Another important concern of the eCS community rumored to be discussed will be the lack of a strategy to take eCS forward as a modern 64 bit OS. A source who may be close to the secretive "Mensys eCS strategy summation" committee (aka MESS), speculated that the consensus reached by the committee was that since not a single developer has bothered to write even one piece of 64 bit software for eCS, there really was no need for the extravagance of a 64 bit eCS OS, however to counter any possible disappointment, it will be emphasized that Mensys is working diligently to replace remaining 16 bit code in eCS, and can foresee the day when an eCS distribution of OS/2 will be 100% 32 bit, and run circles around 16 bit operating systems that are stuck in the past.

Of course the elephant in the room (apologies to Republicans & IBM) will be the lack of eCS wireless support in a mobile wireless 21st century. It's said that Mensys is not out of touch with reality. They fully understand the crisis nature of this problem, and realize that an eCS 2.2 release that doesn't address this issue is "Dead on arrival". To that end it's rumored that Mensys is working around the clock on a solution codenamed "Webesortofwireless" that will improve the compatibility of wireless keyboard and mouse combinations across the board, and prove to the eCS community that Mensys "Gets it".

Surely there will be more "leaked" bits of information as we get closer to this exciting presentation, and they will be reported as they become available.

eComstation.Ru organized an "OS/2 Guru Jam Session" on July 25-26, and has posted the resulting materials. Included are interviews with Alex Taylor regarding eCS components, Paul Smedley regarding porting software, and Lewis Rosenthal regarding supporting businesses running OS/2. There are also IRC transcripts on various topics.

Dave Hart from PlanetECS reports there are several PHP applications that work well on OS/2 with the ports of Apache, MySQL, and PHP, including WordPress blogger software, MediaWiki wiki software, phpbb forum software, extplorer web-based file manager, PHP Dev Shell, a plugin based code management PHP framework, and WebIssues, an issue tracking and team collaboration system, which uses a PHP server, and a Qt4 client that has been ported to OS/2.

Martin Iturbide has written an article offering several suggestions on how users and developers can collaborate for the benefit of the community.

Sander Nyman suggested that the lackluster trickle of OS/2 news could be supplemented with a flood of rumors, and has supplied a few to start it off; feel free to send in your own:

  • Reliable secret sources report that for the first time in 20 years, OS/2 market share has inexplicably reversed it's decline with double digit growth.
  • A private conversation, overheard by an unnamed waiter at a rave party thrown by Lou Gerstner, revealed that Gerstner actually knew that elephants can't dance, but lied because he thought it wouldn't be an effective sound bite.
  • Karl Rove today, in a meltdown that sources say they haven't seen since election night 2012, is rumored to have said that it was actually Barack Obama that was to blame for the demise of OS/2, and, uh, you know, other stuff.

    Since Mensys quietly split off the software development part of their business to, there has been no communication regarding eComStation. For months now, this has prompted questions asking is eComStation dead? Supposedly XEU is still working on eComStation 2.2, although Roderick Klein is no longer with the company. Meanwhile, prominent OS/2 developers who previously collaborated with Mensys are now pursuing alternatives. There are plans under foot to start a new OS/2 company, and some of the major players involved include Lewis Rosenthal, David Azarewicz, and Steven Levine. Lewis Rosenthal shared a few more tidbits - they are working with Bitwise Works, and are planning a Warpstock Europe 2014.

    Martin Iturbide received permission from IBM to republish their OS/2 Courseware from 1999, including the 5 day training course to obtain the "IBM Certified Systems Expert - OS/2 Warp Server for e-business" certification. He has converted it into electronic format and made it available on the Wiki, and is seeking help tracking down the remaining courseware material. The latest addition is OS/2 2.1 for Software Developers; Martin is still searching for some of the other content, so let him know if you have any available.

    A website to locate and download DLL files for OS/2 is now available. The site uses fuzzy-string search, so you don't need to specify the exact filename. Currently there are 2696 DLLs available. From OS2World.

    Flash plugin wrapper version 0.4.2 has been released (2/24/2014) for Software Subscription customers, which requires eComstation 1.2 or higher. It uses an Odin wrapper for the Win32 Flash 11.5 plugin. Supporting Flash 12 or newer plugins will require dinput support in Odin.

    As of 2/11/2014, Mozilla for OS/2 is officially dead; all of the OS/2 support code has been removed from the source tree. One of the primary reasons for this was lack of contributions being sent upstream, and the stated lack of desire to do so, as was predicted several months ago.

    TeamOS2 Hamburg launched a new German-speaking forum as an independent and non-commercial platform for OS/2 and eComStation users. They intend to archive the message base from, and perhaps as well. Thanks to Frank Wochatz for the info.

    The OS/4 project has been running for quite some time, with the goal of updating the "core" or kernel of OS/2. It is likely that their kernel violates some IBM license, since they certainly do not have their permission to create modified works. However, those willing to experiment and ignore the legal murkiness can test out their package, which now includes replacements for the ACPI driver (acpi4.sys), clock driver (clock03b.sys), doscall1.dll, a PSD driver (os4apic.psd), an updated kernel (os4krnl), and a full featured replacement for os2ldr that includes the ability to select which kernel file to boot. Apparently it will boot some newer systems which the regular ACPI drivers do not work on yet. Much information is in Russian, but the package does include English documentation.

    Two new subscriber-only mailing lists are available on the Rosenthal & Rosenthal server: eCS-ISP is for discussions of server hardware and software which are not addressed by another specific list, such as rsync backup issues, server hardware and drivers, and hosting concerns. GNU Ports is geared toward porting Linux apps to eCS. Subscribers must request access and accept the confirmation email. The mailing list convention is to send emails to listname-on to subscribe, listname-off to unsubscribe, listname-digest to switch to digest mode, listname-index to switch to index mode, and listname-request for administrative queries. Thanks to Lewis Rosenthal for the info.

    The REXX Reference Summary HandBook, by Dick Goran, has been scanned and made available online on the EDM/2 Wiki. From OS2World.

    Mensys released (12/13/2013) eComStation 2.2 beta II for Software Subscription customers; OS2World has the readme information. The final release was originally scheduled for the second week of April - perhaps beta III will be out in time for April 2014. Roderick Klein of Mensys previously posted a detailed list of driver updates in eComstation 2.2, many of which have required further updates since then. The majority of user feedback has been positive so far.

    Martin Iturbide received permission from IBM to republish the "OS/2 Warp 4 Certification Handbook" from October 1996. He has converted it into electronic format and made it available on the Wiki.

    Mensys has released another updated eCS 2.2 beta live/demo CD, which allows you to boot the OS on your hardware (but not install it to your hard disk). It includes the latest USB, Panorama, AHCI, DaniS506, and ACPI drivers, and is intended to get additional testing; apparently a new eCS 2.2 beta is planned for the near future.

    There is a nice YouTube video demonstrating a triple boot configuration on a Samsung Series 7 tablet. Windows 7, SuSE Linux, and OS/2 Warp are each briefly compared for basic usage. The pen / touch interface has even been made to function under OS/2 on this tablet.

    Qt version 4.7.3 has been refreshed (3/23/2013) for OS/2. This is a cross-platform application and UI framework. Applications that use QT include VLC, SMPlayer, VirtualBox, Psi, Scribus, and LyX. The QT4 runtime libraries and plugins are necessary for running programs built with the QT4 library. Highlights include printing support through CUPS, drawing using SNAP or DIVE, support for WebKit including SSL, and context sensitive help.

    IBM has officially announced that they will stop selling OS/2 on December 23, 2005, and withdraw support on December 31, 2006. Further details indicate that support after December 31, 2006 will be available for a fee through Service Extensions or Total Content Ownership contracts. There are no plans for any Java 1.3.1 updates (obsoleted by the GoldenCode and Innotek Java offerings), IBM Web Browser updates (obsoleted by Mozilla), or new FixPaks. No new device drivers will be provided after this year. From VOICE News.

    Bob St.John has said that this will have no effect on eComstation. The product plan is to sell it through at least mid-2007. "eComStation will remain available as long as it is a good business. There is no end in sight." Esther Schindler has an opinion article discussing the OS/2 community, and how it hasn't depended on IBM for years. The Inquirer also ran an article recently pointing out how much of the OS/2 hardware support these days isn't coming from IBM. There have been a couple Ubersoft comic strips about the announcement.

    Martin Iturbide reports that there was wide coverage by the press: Slashdot, The Register, OSNews, The Inquirer, Red Herring, Tom's Hardware Guide, PC World, ZDNet UK, NewsForge, WebProNews, WebProNews (2), Softpedia, ATM Workplace, Neoseeker, DesignTechnica, Monsters and Critics, SearchDomino, WebIndia123, BetaNews, CNet News, ZDNet, and eWeek.

    WarpOverlay version 1.10 has been released (4/18/2005) as open source. This successor to HW EnDIVE provides hardware-based video overlay support on top of the SciTech GRADD drivers. This no longer uses DIVE, so it only works on applications that use its API, such as WarpVision. For what it's worth, it was quite easy to add support for my Radeon X600.

    The latest "testcase" OS/2 kernels (14.097d and above) have a new experimental feature, that allows loading parts of DLLs above the 512MB line. "Any DLL objects that do not need to be called by (for code) or addressed by (for data) 16 bit code can be moved out of the low shared arena... this is the place that most often runs out of room, causing sys0008 and similar." Scott Garfinkle gave an example that "saved nearly 11mb of shared memory address space" on his test system:

     EXEHDR /HIGHMEM:1 xx.dll
    where xx is every DLL in mozilla and mozilla/components except npoji6.dll (the Java plugin). Note that for mmparts.dll, you'll need to use an unlock program or boot to a command line. If you have trouble finding the new EXEHDR, you can also try the above512 program.

    IBM has released (12/17/2003) Warp 4 FixPak 17 for Software Choice subscribers. Still available (1/10/2001) is the free FixPak 15. FixPak 17 updates the base level of OS/2 to approximately the same level as Convenience Pak FixPak 4. Device drivers are not included, and can be found in the separate Device Driver FixPak. You will need FixTool version 1.44 to install this. My personal preference is to install it using Fix.cmd from FastKick, which eliminates the need for floppies. From VOICE News.

    BlueCad 1.0 is now available for free. Unfortunately, this CAD program has only continued on the Windows platform. Thanks to Klaus Staedtler for the news.

    Here are some Java tips which may be useful:

    Adrian Gschwend wrote in to announce that GIMP can now (4/7/2003) run on the OS/2 desktop, with the help of Everblue. Gimp is the Gnu Image Manipulation Program, often called the free "Photoshop". It has been available for a long time for XFree86/OS2, and now you can run it without XFree86/OS2 installed. Everblue, the XLib implementation for OS/2 PM, is bundled with GIMP in a WarpIN package for easy installation. There is also a page for the OS/2 version, which has further information.

    The WPS Toolkit web site has been launched at The Workplace Shell has by far the most innovative and extendible interface of all computer GUIs around. Besides giving you a lot of little helper functions, the API of the Workplace Shell Toolkit encapsulates the complexity of the handling of some of the tasks being the most time consuming to code. The following major APIs of the Workplace Shell Toolkit possibly are of particular interest: Text Message File (TMF) Support, Settings and Details Manager, Extended Attributes Manager, and Memory Mapped Files Manager. Among lots of little additional helpers to show up in future versions the following major APIs are on the todo list: XUL support. There is a programmer's guide and reference available.

You can purchase it for the suggested retail price of Euro 239, from resellers such as Mensys. From

    Here's a nice tip for people who are using recent kernels, and have large Windows EXE files (for use with Odin or otherwise). You may have noticed that the WPS takes a VERY long time to display the folders holding these files. The reason for this delay is that OS/2 has to search through the entire file to find the proper icon to display. If you're tired of waiting, add the following to your CONFIG.SYS file:

    Where n is the number of megabytes OS/2 should scan before assigning a default Windows icon.

    IBM has released (8/19/2002) Device Driver FixPak 3, for Software Choice subscribers. eCS customers can find it on the eComstation site. Still available (9/29/2000) is the free Device Driver FixPak 2. Thanks to Andy Willis for the news.

    IBM has released (2/25/2002) FixPak 3 for WSeB, which is available via FTP, and on the Software Updates Page. If you want to use the RSU update, you need to get this fix, or install TCP/IP FixPak UN_2101. Thanks to Klaus Staedtler for the news.

    IBM has released (10/26/2001) updated kernels for Warp 4 and WSeB / MCP / ACP (UNI and SMP), as well as updates to JFS, SES, and the dump formatter. There are lots of fixes, and a couple new features: fine-tuning of the clock scale; support for more than 64MB of memory (for machines that previously required Dani's patch to OS2LDR); the internal revision displayed during boot can be suppressed; and trap messages will show the module name, including traps in 32-bit code. Thanks to R.C. for the news.

    IBM has created updated (8/4/2001) installation disks for Warp 4. They are for ThinkPads, but should work on other systems as well.

    Just like in Microsoft Office, there is a game hidden in the Star Office spreadsheet. Open a new Spreadsheet document, and then enter =GAME("StarWars") in the first cell. It starts a game resembling Space Invaders - the text is German, but it's easy to figure out. From eCS NewsCast.

    Complete text of some OS/2 books are now available at OS/ Advanced OS/2 Programming, Inside OS/2, and Programming The OS/2 Presentation Manager.

They also released (2/27/2001) updates for TCP/IP 4.21 and 4.3 that fix FTP ASCII transfers, and another update (8/14/2000) for TCP/IP 4.3 that fixes traps when connecting to FTP via Telnet.

    IBM has released (1/9/2001) fixpak IP08414 for Warp Peer services. From VOICE News.

    FixPak 43, the last FixPak for Warp 3, has been released (10/18/2000). You can get it via FTP or the IBM Software Updates page. It applies to Warp Server and Warp Server SMP only, because all versions of Warp 3 except Server and Server SMP have been dropped from support.

    MPTS has been updated (4/28/2000) to revision WR08621, which contains a 32-bit TCP/IP stack. It requires either WR08600 or WR08610 to be installed. I recommend extracting the disk images to a directory on your hard drive, and installing it from there, since it is much faster. With this update, MPTS is at version 5.50, and the TCP/IP revisions are: SOCKETS.SYS - 6.2004, AFOS2.SYS - 6.2000, AFINET.SYS - 6.2013. To check your current version, type INETVER at a command prompt. Warning: the problems with the InJoy dialer in 32-bit stacks has gotten much worse with this release; it now causes Trap E errors. From WarpCast.

    IBM has released (4/27/2000) FixPak UN_2101 for TCP/IP 4.21 (included with WSeB). It should be installed with MPTS 8621.

    It seems the 512MB memory limit in Warp 4 has been increased to a maximum of 3GB. With FixPak 13 applied, it defaults to 1GB, but can be tuned via the Config.Sys variable "VIRTUALADDRESSLIMIT=3072" which indicates the value in megabytes, 512-3072.

    For those who have stuck with the 16-bit TCP/IP stack (version 4.0x), MPTS WR08425 is now (1/19/2000) available. This will bring your inetver to 4.02y, and requires 8421 or above to be installed. Thanks to Klaus Staedtler for the news. Also available (12/2/99) is FixPak UN_0980. This contains updates to the 16-bit TCP/IP applications, including FTP, FTPD, NewsReader/2, Syslogd, and TCPCOEX. From WarpCast.

    Martin Hadam reports IBM has updated (8/16/99) the Feature Installer to version 1.2.5. It "contains enhancements for installation reliability and serviceability."

    FixPak 6 and above includes what seems to be a fix for the Pentium F00F bug. To enable it, add the line "BASEDEV=CMPXCHG8.SYS" to your CONFIG.SYS. You may have to copy this file from the OS2 directory to the OS2\BOOT directory. Thanks to Loren Bandiera for the info.

    It's recently been discovered that FixPak 5 and 6 have an extra setting for the WarpCenter. If you add the line "SET MENUSFOLLOWPOINTER=ON" to your Config.sys, the cascading menus work in the same manner as the Windows 95 Start menu; that is, to view the contents of any folder you only need to put the mouse pointer over its icon. Thanks to Loren Bandiera for passing it on.
