6. Primary/Secondary IDE Connectors (two 40-1 pin blocks)
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, you must set the second drive to
Slave mode. Refer to the documentation of your hard disk for the jumper set-
tings. BIOS now supports SCSI device or IDE CD-ROM bootup (see HDD Se-
quence SCSI/IDE First & Boot Sequence in the BIOS Features Setup of the
BIOS SOFTWARE) (Pin 20 is removed to prevent inserting in the wrong
orientation when using ribbon cables with pin 20 plugged).

TIP: You can configure two hard disks to be both Masters using one ribbon cable
on the primary IDE connector and another ribbon cable on the secondary IDE
connector. You may install one operating system on an IDE drive and another on a
SCSI drive, and then select the boot disk through the BIOS Features Setup.
