Jumper 1 – enables you to clear the BIOS. Follow these instructions:
1. Turn the system off.
2. Short pins 2 and 3 on JP1.
3. Return the jumper to the normal setting.
4. Turn the system on. The BIOS is returned to the de-

Jumper 3 – enables you to prevent the BIOS from being updated (flashed).
Set the jumper to disabled if you are going to update your BIOS. After updat-

CPU.
Jumper 5A/B/C/D - this jumper e nables the DDR terminator for DDR memory.
If you installed DDR memory in DDR1/DDR2, short all the jumpers. Otherwise,
if you installed SDR memory in DIMM1/DIMM2, open all the jumpers.
