I used this version of OAK
https://www.hiren.info/download/dos-files/oakcdrom.sys
and the problem persists. I even tried 3 different sound cards with the
CDROM in UDMA and PIO modes:
- SoundBlaster AWE64 Gold
- SoundBlaster Vibra 128
- Yamaha YMF724
It took me this long, because to avoid messing up my system, I have
added additional modes the system can start with, besides the basic 5
present in FreeDOS 1.3 RC5. My extra modes are specific for each sound
card with extra /K parameter for COMMAND.COM so that the drivers are up
and ready as soon as I receive an interactable console. I also needed to
edit the Yamaha driver to add support for the southbridge.
In all 6 tests, the CD input would produce static noise, except with
Vibra 128. Don't even get me started on this card, it's always been an
unstable mess in DOS, courtesy of JEMM386.
Any more ideas? It used to work flawlessly in FreeDOS 1.2 with SHSUCDX
backported from 1.3 RC that was newest like, at least a year ago. It
turned out back then that SHSUCDX from FD 1.2 does not support CD
playback at all.
So, where did things go wrong? Could it be possible that between FreeDOS
release candidates, SHSUCDX changed to fix the issue and then break it
in a new way?
Best regards,
Michał

Not sure about the circumstances of your Rayman crash but I’ve read
many posts about issues with that game on DOS. Apps that access the
file system or hardware directly, disk caches can cause certain types
of file corruption. Whole file system corruption is odd and might
indicate other issues (CPU, RAM, IDE controller, BIOS, drive).
You haven’t provided any details about your hardware. That said, most
drivers had compatibility with multiple drive makers. And usually,
you only had to specify the device “/d:xxyyzz”.
There’s a list of popular device drivers here.

MS used to license OAKCDROM.SYS and CD1.SYS for IDE drives. You can
find other cd rom drivers at
https://www.allbootdisks.com/disk_contents/98.html
I’d try to find your vendor’s driver disk in archive.org
<http://archive.org> or other vintage computing sites.

After working with Rayman I am simply traumatized by crashing
anything
under DOS, because any and every crash can mean the destruction of
the
filesystem's integrity.
I'll try and get the OAK driver and let you know what happens next.
Best regards,
