for a small explanation of why you still would want them on
seperate channels.(I mean a slow device and a fast device)
"...On one EIDE channel, the 2 devices have to take turns
controlling the bus. If there is a harddisk and a CD-ROM on the
same channel, the harddisk has to wait until a request to the CD-
ROM has finished. Because CD-ROM's are relatively slow, there is
a degradation of performance. That's why everbody tells you to
connect the CD-ROM to the secondary channel and your harddisk
to the primary. The primary and secondary channels work more or
less independently of one another (it's a matter of the EIDE
controller chip). "...
