So I've built this Shuttle HOT-419 486 pc to play dos games and the problem is that I can't make ide cdrom drive to work with it, tried connecting it with two different I/O cards, tried two different cdrom drives, one teac and one samsung/Toshiba, both drives work on socket 7 motherboard with built-in ide connector, so issue is definitely not in the drive, mscdex doesn't recognizes any cdrom devices, and during boot bios doesn't shows that anything additional is connected to ide cable besides ide hdd, tried different master/slave combinations, tried even connecting second i/o card additional to vlb one with jumper set to different irq (15 iirc). Nothing works, so my genuine question if there is any way to make etapi ide drives to work with this, I have Sound blaster card Ct2770 that has Panasonic/Creative IDE connector but from what I understand it was designed to be used only with compatible cdrom drives and since I have no such old one I can't test this connector, what can I do to make my Teac CD-520e cd drive work?
