Isn't dumpfs32 from Lars Erdmann? Then he can probably help you with any problems.

Web applications / Re: Dooble releases, Qt5 builds
« on: March 02, 2023, 05:39:46 pm »
when I try to install it with RPM, is says "No package dooble available."  That's the first thing I tried after reading about it on ECSoft

The RPM for Dooble is only available for pentium4, so not for i686.
Try using the Arca Noae Package Manager (use Manage --> Platforms to add pentium4, and make sure it is listed at the top).
After that you should find the dooble package under Available in the left window of ANPM.

Setup & Installation / Re: Old DOS Program on ArcaOS VDM
« on: February 24, 2023, 11:28:41 pm »
Looking at the screenshot you attached, that error message is caused by the DOS Extender that is used by this program - it is not caused by the VDM that is part of ArcaOS. This DOS Extender requires a 80386 CPU or higher.

Better to use ANPM to disable or manipulating /etc/yum/repos.d. Not sure how you will re-enable netlabs-rel after removing it, accept by manipulating the above.

In ANPM use the menu YUM --> Repositories to bring up a window "Manage YUM Repositories" that shows all  installed repositories (both the enabled and the disabled ones).

A right mouse click on a line with a repository allows to enable that repository when it was disabled or to disable it when it was enabled.
Alternatively: select in that window the line with the desired repository and then choose in the menu Repositories the option to enable/disable that repository.

Tools -> Options --> OpenOffice Writer --> Standard Facetypes (Western) ? (sorry, don't know the German equivalents).
You can also find information in the online Help.

Comments, Suggestions & Questions / Re: Hobbes (Files) Reoganization
« on: January 22, 2023, 06:05:46 pm »

Today I got this doubt on where should hobbes kept the "Pre-recorded Demos for products". Those are recorded demos, that is an executable that shows you some multimedia presentation, it may have sound and allow you to make some clicks, but it is not a working demo or a product.

Currently I have those at "/pub/os2/games/toys", which I don't think it is the best place.
The files are:,

What you describe sounds like a "product presentation" or "product introduction". Perhaps in /pub/os2/info/marketing ? (already exists on Hobbes)

I notice that in x:\os2\install\smp and w4 are versions of harderr.exe. Running strings on it, it seems to have the kernel boot messages on it, the tail of strings harderr.exe,
Code: [Select]
EA program in this session encountered a problem and cannot
%@#IBM:14.103#@ OS/2 Hard Error Daemon

So it seems it too should match the kernel.
As for SMP, I wouldn't be surprised if too much is not SMP safe. I tried updating Warp v4 fp15 to SMP, it would trp in under a minute after the desktop came up.

When Scott Garfinkle from IBM still uploaded testkernels to IBM's testcase server, he always put os2ldr, os2dump (forgot this one in my previous answer) and os2krnl into the zipfiles. But never harderr.exe

What other hints do you have for me?
- by replacing the Kernel, wich other files should be replaced as well to match it (DOSCALL1.DLL, ...??)?

I wish all of you a happy, healthy and good new Year 2023, stay safe!!!

And thank you very much!

os2ldr should also match os2krnl, together with doscall1.dll

You too all the best for 2023 and thanks for the many very interesting experiments you have reported about in the previous years!

Edit: os2dump must also match !


can somebody remember a maximum disk size Warp Server 4 Advanced can handle without any update?
Thanks a lot for any hints.


On page 5 of the "User's Guide to OS/2 Warp" that came with my copy of the OS/2 Warp Server 4 Advanced it says:

"If you are installing OS/2 on a computer that has a hard drive larger than 528 MB, see the README.INS file located on the Installation Diskette for important information and restrictions."

I am attaching that file readme.ins (renamed to readme-ws4a.txt to make it possible to attach it here) to this answer.

Programming / Re: Qt6
« on: December 28, 2022, 07:09:24 pm »
HI Dariusz,

Thanks for taking the time to reply. The forum really needs a way to 'react' to posts so at least people can show their interest - even if they have nothing to add to the conversation. I've spent WAY too much time on this so far, and it can be quite demoralising when almost nobody replies. Hardly anyone seems to have tested any of the binaries/ports for Qt6 that I've posted so far  :'(




Since I am only familiar with programming in assembler (though I have become quite rusty because of lack of time), following what you and others achieve in C(++), Python and other ilk is beyond my capabilities. I only admire it from a distance, but appreciate it very much nonetheless. So don't take my silence for lack of interest!

I installed Warp 3, 4 and 4.52 as VM under Virtualbox 7.0.4 in Arch-Linux.
All 3 work per se, even with 1600x1200 SVGA.
Under Warp 3 everything else I tried works too (also with SMP), e.g. emx-0.9d.

Under Warp 4 and 4.52, calling unzip results in an unresponsive DOS-window or SYS3170 for all unzip versions I tried (32-bit and 16-bit).
The same is true for some other utilities I've tested.
Warpin-1-0-26 yields "SYS1057 - file or pathname invalid in a DOS session",
when called from an OS2 window. Double-click in PM on warpin pops up a
window for a fraction of a second.

I tried many virtualization options (nested paging on/off,
PAE/NX on/off, Standard/KVM/Hyper, 1-4 CPU's ...): always the same result.

I compared the Config.sys of 3, 4 and 4.52 and found nothing unusual.

I can't install unzip, hence no zipped utilities. All self-extracting exe's that I tried return SYS3170.
Taking unzip552 as an example for the unzip's tried:
- 32-bit unzip.exe results an unresponsive DOS-window
- 32-bit funzip.exe yields SYS3170 (screenshot attached), same for 16-bit exe's.

What surprises me is that under the older Warp 3 everything works (in the case
of jm Graphics for emx only the PM window works (VESADLL=VESA_PM), but still).

Can someone explain to me what's going on?

Some questions for you.

When you say that you try calling Warpin-1-0-26 from an OS/2 window:
  • what is the exact filename of the excecutable you try to run? Is it warpin.exe or is it warpin-1-0-26.exe?
  • And what is the name of the directory into which that executable resides? Is it warpin or is it warpin-1-0-26?
  • Which filesystem is used inside your Warp 4 and Warp 4.52 VMs? Is it maybe FAT, or is it HPFS or even JFS (Warp 4.52)?

What I find strange in the picture you attached, is that it mentions exception 330d0686. I have never heard of such an exception.

Need to remember the name of the program to nuke the printers and start over I guess.

You mean prndrv.exe? (from Faxworks by the Keller Group, IIRC)

Programming / Re: Samples for VDD Drivers
« on: December 19, 2022, 11:47:20 pm »
Obviously you are not using VDD in the sense of it being the positive voltage in the power supply, so what do you mean by it?

Virtual Device Driver, as opposed to PDD or Physical Device Driver

Hardware / Re: PSCOM.SYS problem
« on: December 15, 2022, 11:16:44 pm »
When loading the system, I see:

DEVICE=C:\OS2\BOOT\PSCOM.SYS (1,A010,21) (2,A000,23) /V

How to make two comports with correct parameters (UART: 16550) be determined?

Try using two 'device=' lines: one with (1,A010,21) /V and one with (2,A000,23) /V

device=c:\os2\boot\pscom.sys (1,A010,21) /V
device=c:\os2\boot\pscom.sys (2,A000,23) /V
