4.2 CPU Installation
The CPU is embedded on the motherboard, so there are no settings for
frequency ratio or voltage.
4.3 Jumper Settings on Mother-Board
4.3.1
LCD panel power setting (JP1)
The Vehicle Mounted Computer's AGP interface supports 5 V and 3.3 V
LCD displays. The default setting is 3.3 V (closed pins 1 and 2), but JP1
can be used to change this to 5 V by closing pins 2 and 3.

Panel Type Setting (JP5)
When the "panel type" value is set to " HW default" in BIOS, the JP5 can
be used to set the panel type to support either 800 x 600 or 1024 x 768
LCD resolution. The default jumper setting for 800 x 600 in the TREK-
775 closes pins 1 and 2; and the default jumper setting for 1024 x 768 in
the TREK-776 closes pins 2 and 3.
