Primary / Secondary IDE connectors (Two 40-pin Blocks)
These connectors support the provided IDE hard diskribbon cable.
After connecting the single end to the board, connect the two
plugs at the other end to your hard disk no space(s) . If you install
two hard disks, you must configure the second drive to Slave
mode by setting its jumper settings. BIOS now supports SCSI
device or IDE CD-ROM boot up (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) .
Tip
:
You may configure two hard disks to be both Masters us-
ing one ribbon cable on the primary IDE connector. You
may install one operating system on an IDE drive and
another on a SCSI drive and select the right one through
BIOS Feature Setup.
