Hello Dracolich,
This is an interesting issue you've got, not sure if I can be of any help.
After reading what I believed was the other thread. Anyway, I'll try..

Some ideas :

a) Did you try to REMove that I2OSOSM.ADD (+I2OXPORT.SYS) device driver from config.sys and see what happens ?

b) Perhaps the BIOS between real PC and VM differs (drive geometry).

c) OS/2 is very sensible when it comes to the file system. It supports FAT12/16B, but also keeps some meta data.
Aliase for long file names are stored in hidden text files, etc. You can run chkdsk /f or chkdsk c: /f from the prompt to fix issues.

d) You can use a backup program to create a full image of the VM's HDD.
I booted the backup program inside of the VM and as a target, I used another VM HDD to store the backup file.

When it was finished, I opened the VM HDD file with WinImage and extracted the backup file and "burned" it onto a CD-ROM.
Back in time, I used Acronis True Image 7 and 9 for this, which also supported compression.

It's backup media also included a DOS-based backup/restore program, which I used, if the other PC was too old.
Once booted on the old PC, the program would re-size/align the backup to the new HDD.

e) Not really related, but the 64MB option was for pre-Warp releases. You can leave it disabled (NO).

Good luck!

Thank you, Jo22. Those are interesting ideas. I did not REM the driver in config.sys since, as posted in the other thread, it did not solve his similar problem.

(c) is interesting. I could try to boot from the floppy to do chkdsk. My OS/2 is installed as a single HPFS partition.

(d) is a lot like what I did. My raw backup from the Quantum disk was created in Linux using dd, giving me a bit-by-bit image of the disk, including boot sector, partition table, etc. PCem is able to mount and use such images (up to 8GB). When the emulated hardware is configured the same as the real hardware the OS doesn't know the difference. PCem also uses real BIOS roms, and the emulated 430VX uses the same Award 4.51g as my 430TX board. I already double-checked comparing the two to be sure the settings matched.

This morning, instead of rearranging my IDE drives, I wrote the backup image to the Quantum disk and installed it as the primary master. Sure enough, it booted with no problem. That means the OS and the config.sys are in good working order. Theoretically, the CF card *should* work as well since it is cloned from the same image. I suspect the problem must be with trying to boot OS/2 from the CF instead of a real hdd. Maybe it reads too fast or maybe DaniS506 can't read it.

If it won't work from CF I can still use it in my VM and from the real hdd. CF would be nice, though 😀

You're welcome. 😀

I do know very little about Warp 4.52, I'm afraid. 😅 Originally, I started with Warp 3.0 and 2.11.
Much, much Later, I got a blue-spine copy of Warp 4.0 again, which I installed and updated in Virtual PC 2004.

That beeing said, I haven't really used any of the newer fixed disk drivers.
However, if they are smart, they sure like to utilize some sort of Multi-Word DMA or UDMA,even.
If that's the case, it couldn't hurt check your CF adapter for the DMA lines.
A few of mine don't have them (they are still good for DOS and 286/386 machines!)

Anyway, good luck. 😀

Thanks again, Jo22. You give me some new ideas. Today I tested a theory regarding disk geometry. In the BIOS I specified the geometry and set to NORMAL then did a clean install. It won't even begin to boot on NORMAL, only on LBA, then on LBA the same problem occurs.

The box my CF-IDE adapter came in states it is capable of UDMA and I am using 80-pin cables. However, based on what you say, my CF might be to blame. I am using a SD-CF adapter with a 1GB SD. The SD-CF adapter is quite old and cannot read higher than 2GB.

At least it's working with DOS. That's higher priority as this rig is for my DOS gaming. 😀
In the near future I plan to do the same with my Win98 rig and will likely get some new CF cards then. I can get better cards then for DOS and OS/2 and try again.

Thanks!

I managed to find a 1GB Compact Flash and transferred my OS/2 image from the SD to the CF. Warp boots happily on this CF card 😀

Thanks, Jo22, for your ideas eventually leading me in the right direction.

You're welcome! 😀

I'm glad it works now.
