FreeDOS also has AWK, which is very practical for text manipulation
but also easy to use:

* http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/unix/awk/

* Learn awk by coding a "guess the number" game
* https://opensource.com/article/21/1/learn-awk

That article also leads to the free e-book:

* A practical guide to learning GNU Awk

Having read both just now, it reconfirmed my opinion that AWK is
incredibly useful (even for non-*nixers) in FreeDOS.

Kudos!

There are 3 versions at 
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/shsucdx.html
 


Version 3.08 & 3.08a are the same, with just NLS updated. However, there is 
also 3.07 and 3.05.

You could try the middle one.

Re: [Freedos-user] UDVD2 vs SHSUCDX

[Michał Dec]

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

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.

https://www.hiren.info/downloads/dos-files

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 
 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,

Michał
