Floppy disk drive ConneCtor
This 34-pin connector supports the standard floppy disk drive ribbon cable. Connect the
single connector end to the ServerBoard. 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
ServerBoard and the floppy drive. The Thin-Type Ribbon connector is specifically designed
for use with Slim Floppy drives that connect directly to the serverboard.
primary ide ConneCtors
The two 40-pin IDE connectors (primary and secondary channels) support 40-wire IDE
ribbon cables. Connect the single connector end to the ServerBoard. 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 jumpers settings. Refer
to the IDE device's documentation for the specific jumper settings. The ServerBoard BIOS
now supports IDE HDD or IDE CD-ROM bootup. (Pin 20 is removed to prevent the connector
from being insertied in the wrong orientation when using ribbon cables with pin 20 plugged
in). The BIOS supports Ultra DMA 33/66/100/133.
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.
