7. Primary / Secondary IDE Connectors (Two 40-1pin IDE)
These connectors support the provided IDE hard disk ribbon cable. After connect-
ing 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 configure the second drive to Slave
mode by setting its jumper accordingly. 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 the BIOS
Features Setup of the BIOS SOFTWARE) (Pin 20 is removed to prevent in-
serting in the wrong orientation when using ribbon cables with pin 20 plugged).
TIP: You may 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 an-
other on a SCSI drive and select the boot disk through BIOS Features Setup.
