	Hmmm, well, I'm not entirely surprised that there were issues trying to 
boot from the secondary IDE slave CD drive. If there are still troubles, 
try having _only_ the 20GB HDD connected as Primary Master, and the 
faster/newer CD drive as Secondary Master.
	As far as my suggestion on drive locations, it's related to what gets 
used more. About 90% of the time, CD drives aren't used. So if you have 
the2 HDDs on separate channels, there is no congestion to fight with 
from the other HDD. Same reason that when you setup a software RAID 
system, you put only one drive on each IDE channel - performance.
