9. Primary / Secondary IDE connectors (Two 40-1 pin block)
These connectors support the provided IDE hard disk ribbon cable. After con-
necting the single end to the board, connect the two plugs at the other end to
your hard disk(s). If you install two hard disks on the same channel, you must
set the second drive to Slave mode. Refer to the documentation of your hard
disk for the jumper settings. BIOS now supports SCSI device or IDE CD-ROM
bootup (see HDD Sequence SCSI/IDE First & Boot Sequence in BIOS Fea-
tures Setup of the BIOS SOFTWARE) (Pin 20 is removed to prevent insert-
ing in the wrong orientation when using ribbon cables with pin 20 plugged).
