Greetings,

New here so be nice 😁 ...
I've built a retro computer recently with the following specs:

  • Socket 7 Motherboard
  • Pentium I @133Mhz
  • 16M RAM
  • IDE 52x Creative CDROM
  • 2G compact flash -> IDE
  • Standard 1.44 3 1/4 Floppy Drive

So far, everything has worked great. For some reason I'm having issues getting the CDROM to show up. The BIOS picks it up for sure.
I have the compact flash card connected to MASTER of IDE-0, and the CDROM connected to MASTER of IDE-1. I have set the jumper on
the CDROM drive to the MASTER setting. On POST, the Sec Master shows as CREATIVE CD6220-F. After the box boots up, it shows that
the CDROM is the secondary master as well. However, I can't CD to D: I don't see anything in the BIOS that allocates a drive letter to it
though. It's been a very long time since I've had to mess with this 😁

I tried setting the primary boot device to the CDROM and it said it was attempting to read the master boot record from the CDROM, however
the LED didn't come on or anything. I got this drive brand new as NOS on eBay. I suppose the drive could be bad, but IIRC these things just
worked back in the day.

Yup I'don't say everything is fine, you just need to (in DOS) load an ATAPI driver (e.g. OAKCDROM.SYS) and drive redirector (e.g. MSCDEX.EXE). If you have access to a Windows 98 boot disk, you can see a good example (including the files themselves).

So I used the oakcdrom.sys in Autoexec.bat and config.sys and it mounts. However when I cd to D: I'm getting the good old "Drive not ready, Abort? Retry? Fail?"

The CD light doesn't come on even. I see there's PIO modes in the BIOS. I've tried all to no avail. Thanks for the feedback as well!

Well, what you can do is put a CD in the drive before accessing to D:

Is like a floppy, when you don't have a floppy inserted on the drive nothing happens xD

Now to the serious part:

Double check that the settings in config.sys and autoexec.bat are correct, here is an example of my own way

autoexec.bat

MSCDEX /D:MSCD001

config.sys

DEVICE:C:\DOS\OAKCDROM.SYS /D:MSCD001

Give my tips a try, it should work, if it doesn't work you need to take the CD drive apart and clean the lens, sometimes humidity and dust from being stored in the box can make the lens foggy or dirty, rendering them unable to read

P.D: Almost forgot, when you turn on the machine open the drive and close it to check if it works correctly on the logic and motor side BTW ;3

In addition to that which has already been stated, remember the first rule of technical troubleshooting: replace suspected bad with known good. Test the drive in another system without such issues, test a known-working drive in the system with the issues.
