Grafx and John: What chipsets do your motherboards have, and are you using IDE drivers supplied my the manufacturer or are you using the IDE drivers supplied by Windows?
Also, you should check which version of ASPI (if any) you have. You can find out which version (if any) you have with Aspi Version Checker. Search for "aspichk.exe" at http://www.adaptec.com
. If you don't have ASPI, you should download and install it. 4.60 seems to be the best version. You can find it at the Adaptec web site by searching for "aspi32". It says that it won't work on Windows XP, but I am running a version of 4.60 (it came on the install CD for an old CD-RW drive) with no problems on my Windows XP computer.
