Hi all, I have an ISA Input/Output controller card that has the name "Super I/O Card" and I have connected the 1.44mb floppy drive and IDE hard drive as master and the DVD drive as Slave but the DVD drive is not being detected im wondering if this is a limitation of the controller card as I have tried another I/O card and the DVD drive works but since my second I/O card does not have a com port for a serial mouse and the Super I/O card does have a com port I have tried to connect both cards at the same time but with both connected the Super I/O card stops the second I/O card from detecting the HDD, I have tried using different ISA ports but it does not help. The 486 motherboard im using does not really have any options in the bios for IRQ settings.

Connect the DVD drive to the secondary IDE port with no other device on the same cable.

Not detected in general (BIOS), or when it boots to DOS and/or Windows? The only motherboards that detected the CD drives in the BIOS was on the Socket 5 and higher boards. On a 486, there are two boot options: floppy or Hard drive, and to actually boot from a CD, you need PloP Boot Manager on a diskette.

Disclaimer: I don't know if this the case, just throwing in an idea.

Quite a few I/O cards don't work with ATAPI drives. If you have some ancient CDROM drive try with it just to rule out the possibility.
I would tell you to try to find and have a look at the official manual for your card but even if you manage to find it it's not conclusive. There's a chance that it doesn't clearly state that it only works with IDE drives because they weren't aware of ATAPI then.
