Components and Jumper Setting
Primary IDE connectors
The two 40-pin IDE connectors (primary and secondary channels)
support 80-conductor IDE ribbon cables. Connect the single connector
end to the Mainboard. Then, connect the two connectors at the other
end to your IDE device(s). If you connect two hard disks to the same
cable, you must set the second drive as a Slave through its jumper
settings. Refer to the IDE device’s documentation for the specific jumper
settings. (Pin 20 is removed to prevent the connector from being in-
serted in the wrong orientation when using ribbon cables with pin 20
plugged in). The BIOS supports Ultra DMA 33/66/100.
Floppy Disk Drive Connector
This 34-pin connector supports the standard floppy disk drive rib-
bon cable. Connect the single connector end to the Mainboard. Then,
plug the other end of the ribbon into the floppy drive. Make sure you
align the Pin 1 on the connector with the Pin 1 alignments on the
Mainboard and the floppy drive.
IMPORTANT
Ribbon cables should always be connected with the red stripe on the
Pin 1 side of the connector. IDE ribbon cables must be less than 46 cm
(18 inches) long, with the second drive connector no more than 15 cm
(6 inches) away from the first connector.
