NOTE
The HD Active Display connector (J44) is used for external SCSI/IDE adapters to
display hard drive activity.
CAUTION
Do not use the password clear jumper (J32); use instead the clear CMOS jumper (J29).
Using the clear CMOS jumper then sets all other CMOS settings back to the defaults.
Settings shown in bold italics are factory defaults.
