Well, the real WTF here is that the installer is so crappy it can't even properly interleave between the two drives. I have had that setup (where a HDD shares the IDE link with a CD drive) for years and never noticed any slowdowns while in Windows itself (never tried the installer with that setup).
Ahh, but I'm betting both of your devices on the same chain are NOT both set to be the master device, which is what I believe the OP was getting at. . .
