I'm assuming you may have two of these drives on the same cable.
If you have disconnect one so that there is only one on the cable.
Also consider using another cable for the drives in case the old one is bad.
>> Question: Do i SET ALL 3 DRIVES to CS, and disable the zip drive ? Or better yet, precisely HOW do I set the jumpers? Thanks again.
Disconnect ZIP drive. Disconnect one CD/DVD drive as above. Try installing with only one CD/DVD drive and one hard drive. You set both of these drives to CS for install purposes.
