We are using a Compaq Prosignia 200 and the BIOS Setup automatically 
validates and resolves conflicts for me when I press F8 ;-) Seriously 
though it's choices appear to be valid (IRQ 5, 10, 11, 12 (if the mouse is 
off)) when it finds conflicts etc.

Subject: 	Re: Problems with dual Adaptec 2940-UW controllers

	We've used two 2940 (not UW) in an old P133 here, so it _should_
	be possible :)

	What IRQ does the second card end up with - is it possible its
	being used by something else in the machine, maybe an ISA device?
