1-F. Memory Clock
The memory clock can be set to run at the CPU
clock speed or to the AGP bus speed (normally
66MHz). The benefit of this setting is that you can
run the CPU bus at 100MHz with only 66MHz
memory by setting the memory clock jumper to
AGP.
Hardware CMOS & Password Reset
If you have been locked out of
your system because you forgot
your password or set the CMOS
incorrectly, follow the instruc-
tions below.
1. Power off the system
2. Set jumper JP13 to pins 2 and 3
3. Wait for 2 seconds, then return
jumper JP13 to pins 1 and 2.
4. Power on the system again.
By following this procedure, you
will erase your password and
reset the CMOS to the BIOS
defaults.
