From your pictures you have a CD-ROM manufactured by Matsushita for IBM with a model number of CR-563BBZ. This drive uses Matsushita's proprietary interface, so won't work with the the OAKCDROM.SYS driver which only supports CD-ROM drives using the IDE interface. It is however not connected to your sound card, its connected to it's own LaserMate CD-ROM interface card (labelled LMEP0084C). Your sound card is just behind it, it's the card with the silk screened CT2770 at the top.
I'm not sure if your LaserMate interface card needs its own drivers, or if it's compatible with the Matsushita interface card and so can use the Matsushita drivers. If it is compatible then what you need to do is copy
CDMKE.SYS to the root directory of your boot floppy. You'll then need to add the following line to your
DEVICE=CDMKE.SYS /D:MSCD0001 /P:300
You'll also need to copy the file
MSCDEX.EXE to your floppy and add the following command to your
AUTOEXEC.BAT if it's not already there:
If the device driver
CDMKE.SYS fails to load, displaying a message like
Interface board or CD-ROM is not ready., then you can try each of the following numbers for the the
/P: parameter: 310, 320, 340, 350, 360, 370, 380, 390, 3A0, 3B0, 3C0, 3D0, 3E0, or 3F0.
However if it doesn't work the first time, then I would suggest disconnecting the CD-ROM drive from the interface card and connecting it to your sound card instead. The model number on the card, CT-2770, indicates that it's a Sound Blaster 16 Value which should also have Matsushita proprietary CD-ROM interface. You'd then need to change the line added to
CONFIG.SYS above to:
DEVICE=CDMKE.SYS /D:MSCD0001 /SBP:220
Other numbers you can try with the
/SBP: option are 240, 260, and 280. However your Sound Blaster 16 is very likely using port 220 and you can verify this by checking to see if the jumpers labelled IOS0 and ISO1 at the bottom middle of the board are both installed. If they're not both installed then it's using port 240 if ISO0 is not jumpered but ISO1 is jumpered, port 260 if ISO0 is jumpered but ISO1 is not jumpered, or port 280 if neither ISO0 nor ISO1 are jumpered.
