1. Why don't you tell us how the IDE devices are configured (jumpered and cabled):
a. How is the hard drive configured:
(1) Is it on a 40-wire 40-pin or 80-wire 40-pin ribbon cable?
(2) Is it on the end (black) or middle (grey) connector?
(3) Is it the only device on the cable?
(4) How is it "jumpered" (single, master, slave, cable_select)?
(5) Which IDE port is the cable connected to (primary or secondary)?
b. How is the DVD drive configured:
(1) Is it on a 40-wire 40-pin or 80-wire 40-pin ribbon cable?
(2) Is it on the end (black) or middle (grey) connector?
(3) Is it the only device on the cable?
(4) How is it "jumpered" (single, master, slave, cable_select)?
(5) Which IDE port is the cable connected to (primary or secondary)?
