Hey, I found an isa card i need some info on. It looks like it has ide support on it. and has two numbers on it:
[engraved] PCB NO. 400599-97 PCB rev B
[on a sticker] 400586-01

does anyone know anything about it?

You're probably not gonna find much using the PCB number, the 400 number may be a part number U can use in your search engine.
It's probably an IDE adapter for a specific and old CD drive, or it could be an old IDE adapter that was used on an 286 or early 386 that supported 2 IDE devices.
If you find anything at all it won't be drivers just some jumper settings that might also config it for serial/parallel ports.
