Check all the Jumper Settings
Check all the mainboard jumpers to ensure that the board is configured correctly.
A Note on Jumpers
A jumper consists of two or more pins mounted on the mainboard. Some jumpers
might be arranged in a series with each pair of pins numbered differently.
Jumpers are used to change the electronic circuits on the mainboard. When a
jumper cap is placed on two jumper pins, the pins are SHORT. If the jumper
cap is removed (or placed on just a single pin) the pins are OPEN.
JP1: Clear CMOS Memory Jumper
This jumper lets you erase the system setup settings that are stored in CMOS memory.
You might need to erase this data if incorrect settings are preventing your system from
operating. To clear the CMOS memory, turn off the system, disconnect the power cable
from the mainboard, and short the appropriate pins for a few seconds.
