So the saga of my 486 build continues (previous post is here New 486 Build). I have the motherboard, video card and sound card all working thanks to the new AT PSU I got from NewEgg. I have my hard drive running from the Promise EIDE2300 Plus I/O card. I used overlay software to get a new hard drive to work with it. It has been really difficult getting the ATX case to work with this old hardware, the worst part being the height of the cards not being correct so that they do not slot in far enough. But with a bit of brute force and bending of metal they are in and working now.
The problem I am having is that I cannot get the CD-ROM drive to be detected when plugged in to the I/O card or when plugged in to the CD-ROM connector of the CT2770 Soundblaster 16 Value card. I am using Phil's startup files from http://www.philscomputerlab.com/ms-dos-starter-pack.html. Is there a different way to get these old CD-ROMs to work?
Edit ** I just noticed that the Promise card is not the same card as the box it came in. The one on the box has an IDE and CD-ROM connector. The actual card only has an the one marked IDE drive. Does that mean that you can only connect hard drives to this I/O card? I could still use the IDE connector on the SB-16 but I can't get that to work either. Maybe there was specific software to get CD-ROM drives to work when connected to a Soundblaster? The I/O card I actually have is made by Promise and has "DC420" written on it if that means anything.
