PTM900 Mainboard Manual

1.) Set System Jumpers

Jumpers are used to select the operation modes for your system. Some

jumpers on the board have three metal pins with each pin representing a

different function. A 1 is written besides pin 1 on jumpers with three pins. To

set a jumper, a black cap containing metal contacts is placed over the

jumper pin(s) according to the required configuration. A jumper is said to be

shorted when the black cap has been placed on one or two of its pins.

NOTE: Users are not encouraged to change the jumper settings

that is not listed in this manual. Changing the jumper settings

improperly may adversely affect system performance.
