JP13
Normal
If you have been locked out of your system because you forgot your password or set the CMOS incor-
rectly, or have just finished flashing your BIOS follow the instructions below.
1. Power off the system, and disconnect the power supply
2. Close JP13 (see mini-map for location of JP13)
3. Wait about three seconds
4. Open JP13, then power on the system again
By following this procedure, you will erase your password and reset the CMOS.
If you have a non-retail/engineering sample CPU, you will also need to close J29
(see mini-map for location of J29) as well as JP13.

2.6-C. CPU Front Side Bus Jumper (JP1)
close
JP1
100MHz
With this jumper, the CPU's FSB can be set to either 100 or 133MHz.
Only non-retail/engineering sample CPUs are affected by this jumper. Retail
CPUs have their FSB locked in. If your CPU can only run at 100MHz, opening
JP1 will not make the CPU run at 133MHz.

tion of the CPU using different settings from those of the CPU manfacturer's spec-
