First, Is the sound card cdrom interface ide? if so, you should disable the soundcard's cdrom interface and move the cdrom to the secondary ide port on-board. If it is a proprietary interface, I would disable secondary ide in cmos if you are not using it to free an IRQ for the soundcard. If you have an ISA soundcard you probably have to run the dos install utility for it to set up the card for plug-n-play. The few ISA soundcards i have used could not be configured by the BIOS for plug and play, but could be by the soundcard's dos install utility. Refer to the soundcard manual if you have one. Thereafter, the bios would sort of work around the soundcard during plug and play initializing and everything would work without conflict. Second, you may have to include the dos driver in config.sys for this cdrom. A properly installed ATAPI cdrom will have its drivers loaded during windows startup, so pre-loading drivers in config.sys is unnecessary. However, if the drive is not being recognized by windows, loading drivers in config.sys will force windows to add it to device manager. I would experiment to see if the rem should be removed from autoexec.bat for mscdex, keeping in mind that the /D: parameter would have to be changed to match the /D: parameter used with the device= command for the soundcard's dos install utility driver in config.sys. As I said before, this all assumes you are using an ISA soundcard that does not plug and play well. If you have a PCI soundcard, they typically use the Secondary IDE interface for a cdrom, so you may have a conflict with the ide port where the new cdrom is installed. Go into cmos settings and disable the secondary ide channel and see if that doesn't fix it.

When I loaded Win95 on this machine, I temporarily attached a modern CD ROM to help speed the install, it was as one would expect, attached to the IDE controller on the motherboard. The problem is that now that I have detached the new CD ROM and reattached the old one to its sound card, Windows fails to find it. Add and Remove new hardware doesn't find it either. Can someone tell me how to resolve this. The unit does work. It is a Creative CD ROM and plugs into a card from the same makers with model number CT2260. I downloaded drivers for the sound card okay, but am lost as to what to do with the cd ROM. For those interested the Config.sys has "Device = C:\WINDOWS\Himem" and Autoexec.bat has " rem - by Windows Setup - C:WINDOWS\COMMAND\MSCDEX /D:MSCD001 /V". I take it that Windows remarked the Autoexec entry because it failed to see the device, once the newer CD ROM drive was removed.
