7. Primary / Secondary IDE connectors (Two 40-pin Block)
These connectors support the provided IDE hard disk ribbon cable.
After connecting 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. Please refer to
the documentation of your hard disk for the jumper settings. You may also
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. 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 inserting in
the wrong orientation when using ribbon cables with pin 20 plugged).
