Is there a chip with a number you could read?

Unless they're for raid, I assume they use the same pci interface as ever other ide controller - I've never seen one which dosent work. Standards are a good thing :) THat said, even raid controllers work as standard ide controllers if you dont have a driver to speak to the raid part. e.g. with a highpoint raid controller I had, but with no driver, I had /dev/hd{e,f,g,h} (as linux would see it, although that happened to be a bsd system)

What kind of errors or symptoms did you get? The only problems which would be immediatley obvious to me would be with pci steering, but that shouldnt really cause trouble here.

Wow, 200GB - the biggest drive I've ever bought is 20GB, but then i'm a poor student :)

I mean the adapters you can get which let you plug an ide drive into a scsi bus - they're about $30. I got one when I was desparatley trying to find things to work on a non-standard single-ended bus for a pa-risc machine.
