Hi,
Usually you should connect the Hdd to Primary IDE channel as Master and the
Optical drive to Secondary IDE channel as Master. Both drive jumpered as
master or cable select.
Always connect the fastest drive as master and the slower drive as slave in
the same IDE channel.
For best performance, I would suggest you to use the 40 Pin 80 wires
shielded IDE cable for both drives; jumper both drives as cable select.
