Installing OS/2 Warp, Internal CDROM Drive Connected to a Soundcard Directly (Not a Separate Controller Card)

INSTALLING OS/2 WARP, INTERNAL CDROM DRIVE CONNECTED TO A SOUNDCARD DIRECTLY (NOT A SEPARATE CONTROLLER CARD)
Last updated: 27 Dec 1994

DESCRIPTION OF SYMPTOMS
Not recognizing cdrom. OS2CDROM.DMD not found.

RESOLUTION
This is a hardware related problem. User needs to do the following:

On the back of the cdrom drive is a jumper which controls the bus device number. OS/2 install requires it to be on 0 (zero).

Most sound board manufacturers leave it at the factory default of 1. If it is anything other than 0, the install disk #1 will not load the driver " OS2CDROM.DMD " and will stop installation with a red screen saying it can't find the cdrom.
