LED
There are two SCSI LED headers
(J10E1 and J10A1) on the board.
If you connect a SCSI card's LED cable
to either of them and connect the Hard
Drive Activity LED on the front panel,
then the LED will work either when the
IDE hard drive or the SCSI drive is
operating.
When using a SCSI controller card with
an activity signal, connect a cable from
the card's drive activity header to
header J10E1 or J10A1.
IrDA module
Front Panel power switch that pulls the
SW_ON# pin to ground for at least
