cables blue connector to the motherboards primary (recommended) or second-
ary IDE connector, and then connect the gray connector to your UltraDMA/100
slave device (hard disk drive) and the black connector to your UltraDMA/100
master device. It is recommended that non-UltraDMA/100 devices be connected
to the secondary IDE connector. If you install two hard disks, you must config-
ure the second drive to Slave mode by setting its jumper accordingly. Please
refer to your hard disk documentation for the jumper settings. BIOS now sup-
ports specific device bootup (see 4.4.1 Advanced CMOS Setup). (Pin 20 is re-
moved to prevent inserting in the wrong orientation when using ribbon cables
with pin 20 plugged).
TIP: You may configure two hard disks to be both Masters with two ribbon
cables one for the primary IDE connector and another for the secondary IDE
connector. You may install one operating system on an IDE drive and another on
a SCSI drive and select the boot disk through 4.4.1 Advanced CMOS Setup.
IMPORTANT: UltraDMA/100 IDE devices must use a 40-pin 80-conductor IDE
cable for 100MByte/sec transfer rates.
