Hello, I have a 486 machine that I am trying to get an IDE CD working on. The sound card I installed has IDE, so I figured I'd use that. Unfortunately, I have been unable to get it working so far after a few hours of troubleshooting. I have tried several cables, several drives, and I have tried editing the Autoexec and config.sys many times. I have gotten it to where the driver ties to load, but finds no drives at all.

This is the card if it helps:

And here are the autoexec and config.sys:

Here's the computer and the messages at startup

from the trw photo it seems like the ide controller works on irq 12 or 15, yet your config sys refers the vide-cdd.sys to look at irq 11.

I think that should be the first thing to correct.

Right to repair is fundamental. You own it, you're allowed to fix it.

I changed it to look at 12(what it’s jumpered at) but that didn’t seem to help. I also changed the i:b to an i:a to see if that didn’t anything. Nothing changed.

It seems that flashing the ROM may help - Can't use IDE port on BTC 1857i card

But note that was about an ES1869 card, while yours is based on ES1868.
Decide for yourself if you want to take the risk...

The letter after the "i:" is actually a hex number. a = 10, b = 11. You want to use "i:c", which will select IRQ12, what your card is jumpered for. That should get it working.

Does the mainboard itself have a spare IDE?

When add-in cards have the same peripherals as the mainboard, I always think about possible conflicts.
If the mainboard has an available one, I'd remove the sound card and see if I can get the drive working
directly connected to the mainboard (and your BIOS might be able to report seeing it) - even if you ultimately
want to put it on the other interface, this would at least tell you if other things are configured right..

I assume you've already checked that the drive is jumpered correctly - drives could have been left jumpered
either way - when placed alone on a secondary IDC channel, they were usually jumpered as drive 1. When
daisy changed with the main IDE hard drive they were usually jumpered as drive 2.

I’ll have to try that, that might be it. I’m sure it would have been easy if the manual actually told me that(which it didn’t)

No onboard IO, so I have multi IO card. It only has one IDE channel, and I’m not sure it supports atapi devices.

If there is a PS/2 mouse connected (or maybe even PS/2 mouse support active without an actual physical mouse connected), using IRQ12 for whatever else may be problematic.

Try jumpering it for irq15 then
