SCSI Termination Enable/
Disable (H8DA8-2 only)
Jumpers JPA2 and JPA3 are used to
enable or disable termination for the
SCSI Channel A and B connector, re-
spectively. The default setting is open
to enable termination. See the table on
right for jumper settings.
Note: In order for the SCSI drives to
function properly, please do not change
the default setting (enabled) set by the
manufacturer.)

Jumper JPUSB is used to select the
power state for the USB ports. The
Standard setting means power is ap-
plied to the ports only when the system
is powered on. The Dual Power setting
will allow the USB ports to have power
whenever the system's AC power cord
is connected, regardless of whether the
system is powered on or not. See the
table on right for jumper settings.

Jumper JPI1 is used to enable or dis-
able the onboard IEEE (Firewire) head-
ers. See the table on right for jumper
settings.

either master or slave status a compact
fl ash card installed in IDE1. See the
