Re: 2 EIDE interfaces. Connecting 2 IDE HD + 1 CDROM.



AFAIK,
item 2 is _not_ correct for UDMA interfaces (UDMA33 and above - everyone
does those today), as it multiplexes the calls to the drives, so the faster
drive can get more calls done while the slower one is still processing.
I could be mistaken , though..
