Multimedia / Re: OS/2 Warp 4.52 VM, changing audio to Uniaud

Hi Martin,

  Strange there is no folder with the soundblaster drivers... I guess you will have to find the original driver package and use that (maybe at Hobbes - or on the OS/2 Warp disk you used?). Open a command prompt, navigate to the folder with the soundblaster install files, then run Minstall there. Use '0' (zero) for the number of cards in order to remove it.


Correct you are one of the few OS/2 users that know the above :-)

Hi Pete

I can not find that MMOS2 directory on the Warp 4.52 CD.


You can not its not there... Well it it. It still lives in pack file in \os2image. In eCS and ArcaOS there is \MMOS2 directory.


Applications / Re: Dooble completely hangs ArcaOS
« on: September 17, 2022, 10:56:36 pm »
I finally decided to install the Dooble browser. Unfortunately it didn't go so well.  :-\ For the installation I used Netlabs repositories via ANPM. The browser starts but after a few seconds it crashes the whole operating system, the mouse cursor hangs and the system becomes unresponsive. Even CAD-popup doesn't work and the only solution is power off the machine. Am I the only one having these problems? My ArcaOS installation is up to date and there are no updates available for any of the installed packages.

Do you have kernel 14.203 installed and the latest ACPI version and Uniaud ?

There is indeed a very very long list of reasons.

OS/4 mentions not a decent Office Package. Warp 3 came with IBM works, it was a hell of lot more then Wordpad. I mean at the OS front OS/2 was hit by Microsoft. But look wat happened to Lotus 1-2-3-> Excel. Wordperfect which was well the defacto DOS word processor. Word and Excel pushed these guys out of the market as well.

IBM did pay vendors to publish games for OS/2. Such as Maxis that published Simcity 2000 for OS/2 and some other game vendors.  But indeed this was to little at to late.

With people getting Windows 95 at home according to one analysis I read a few years ago. People at large companies started to complain why they should use OS/2 at work if they had Windows at home...

As for the driver support that is true. What I think what has also not helped is that CD drives had different standards. Not all CD ROM's where supported by OS/2. With Windows 95 you could load a DOS device driver. Making it easier....


Programming / Re: SIO, SIO2K

Even the IBM drivers work with current PCI serial cards.

What would be nice is serial support to work with PCIe cards. An active developer could get it done.

USB serial support is pretty good, so we do not really lack for solutions.

Well there is text file in the OS2 or OS2BOOT you can update and see if PSCOM that ArcaOS ships with can be made to work.
David from AN has continued to update PL203 support in USBCOM.SYS driver.

For me SIO2K has become a write off. If the community could have had the code 10 years ago.
But even if we have thc code. We have plenty of samples floating around.

Then the legal issue that popups. Is Ray Gwiin his code based on DDK code yes or no ? So even if somebody has the code what could you do with it ? Also who could work on it ?

If the goal is to get PCI/PCIe  cards to support serial ports. I think the bottom line is that its easier to get PSCOM.SYS updated then to try and get SIO2K.SYS its sources. Its light years behind is my guess. Somebody would need a lot of time to update support for PCI serial ports.

That is my take on it.

The domain name that is your email address is SPF and DMARC setup correctly ?

Goto and put your domain name to check if stuff is setup correctly.
Is your SPF record also needs to have the correct entries.

Dmitry is currently still traveling. He is now working to get settle within the EU. I visited him in Turkey about 1 month ago.
So for now the work on the browser is kind of on halt.


Events / Re: User Meeting Cologne November, 5th 2022 confirmed

Hi Remy

we have not decided wether we will record the meeting on video or not. We will discuss a live stream as well, but Thomas and me are not experts in this case, we will have a look at this even though.

Please give us more information on the travel topic. I do not understand what you exactly mean, sorry for this, I have to apologize.
I guess you - if at all - would travel from France to Germany and I do not see any restrictions regarding this. Do you have a link for me where I can get further details? Thank you in Advance!!

When I organized WSE in Cologne, it turned out the internet connection in the youth hostel a few years ago was REALLY bad. They said they would get a fibre optic internet connection. So a video stream would be very difficult. At the time they had they had a few stacked DSL lines. When a busload of students arrived the video stream was dead. I streamed the video stream in the end via my mobile phone. I can help with that if I am present.


General Discussion / Re: eCS 2.2 purchase

You will never know how much of system memory (RAM) is mapped below the 4 GB physical address line.

Newer systems tend to reserve a lot of the physical memory space below 4 GB presumably for the PCI(e) bus so that you can use older 32-bit PCI cards/devices, potentially requiring large amounts of physical address space (like, say a 32-bit PCI graphics card with 2 GB of video memory: it needs 2 GB of physical address space below the 4 GB address line). Newer 64-bit PCI cards are of course not suffering from this problem.

It's just a fact that every modern OS is 64-bit by now, which means, it has no problem accessing system memory if it is mapped to physical addresses beyond 4 GB and therefore it is not affected by this limit. And therefore manufacturers no longer care about this limit.

Testing ArcaOS 5.1. beta (I am on the tester team) I have seen systems where all PCI devices have 64 bit MMIO addresses (I had one of these laptops). The UEFI loader remaps these back to 32 bit MMIO address ranges. Now the video card could be an issue using a lot of memory below the 4 GB. However more and more video cards have something called PCI bar resizing. This *might* help de amount of reserved RAM be reduced. When I have such a laptop I will test again and see if that is indeed the case.

I am testing a system here with UEFI firmware (1 year old) and I have 3.3 GB of RAM. It depends on the system.

It is not to undermine the free will. Its rather to see how we can try and learn in this forum to see how we can possibly analyse WHY a program crashes.

Who ever made a memory dump or process dump  and loaded in PMDF ?


Hardware / Re: ArcaOS 5.1 UEFI support - GOP?
« on: May 28, 2022, 06:07:07 pm »
With the phase out of the BIOS, the VGA BIOS and VGA hardware is also gone. That is pretty big step! VSVGA.SYS is basically a big wrapper around the video BIOS and VGA hardware. VEFI.SYS partly emulates the VGA hardware. So there is some slowdown, but on new UEFI only systems the system is that quick you should not notice it.  But it should be faster then DOSbox possibly, because the rest of the hardware is "real".

A lot of the stuff for me does not look totally unknown as I looked at in my Mensys days working on eCS... It just never got of the ground.

All this info you can find in youtube presentations from alex taylor he did for warpstock europe.

Thanks, Roderick, I'll check it out. Sadly, if there were captions (auto-generated or otherwise) on the video, a Google search didn't pop it up when I was searching :(.

Try this


How big is DUX, can you ZIP up the program and send it to I will try and debug it here and see if I can find the reason for the crash.

Its not any statements against anybody or OS/4. You should not recommend to swap key system files to get an application to work. I think we should rather start to learn how to analyze the issue at hand and see if we can fix possibly. If you put an old version of PMMERGE.DLL, what can then be broken ?

That's my fault and I apologize. I saw mention that the trap was happening in PMMERGE.DLL and I remembered that the OS/4 team had squashed some bugs in that, so I figured it was worth a shot to try.

Nobody is to blame at all. All suggestions are well intended. I just do not see you should swap a key system file.  OS/4 has fixed some bugs in PMMERGE.DLL. But I did not know what exactly fixed and that is why I asked what bugs where fixed. I suggested asking for the information so we could possibly find out what was causing it. But sadly PMMERGE.DLL is a big DLL and a lot ways this DLL can crash. Its one of the core PMSHELL DLL's.
The crash could be caused by an installed font. Does the DUX program install any extra fonts for example ?

I thought it would have been a great learning project to debug the issue on the forum. The stuff how to read popuplog.os2 is document by IBM in PDF's, Martin has these. And Martin I think knows what PMDF.EXE is for ?, which I also suggested we could use to load a procesdump.
We could have use Steve Levine his script for this  to create a procdump.
How many people use this to debug crashes they can not figure out ?
