BIOS.

Set Power up FSB frequency to 100MHz if the user
wants to run the CPU at an FSB frequency of
100MHz or higher. This setting will allow the user to
run the CPU at a higher FSB frequency, especially
when the user wants to urn a 66MHz FSB CPU at
100MHz and higher FSB frequencies.
Note
: The “Manual” mode setting facilitates FSB over-clocking. Doing so will however force
your CPU to operate out of its specifications, and therefore SOYO can not guarantee the
proper function of your system.
Step 5. Set the CPU Frequency
This Motherboard does not use any jumpers to set the CPU operating frequency; theCPU
settings can be changed through the BIOS [SOYO COMBO SETUP]. Please refer to
Chapter 3 “Quick BIOS Setup” for details on setting the

processor frequency.
Step 6. Set for JP9 FWH Boot Block Write-Protect
Setting this jumper to open will prevent the boot block area of the FWH (FirmWare Hub) chip
from being written data into such that it is write-protected from unwanted or abnormal write
activity.
Note
: In some rare cases, the boot block area will need to be flashed to complete the BIOS
upgrade procedure. Setting JP9 to open will cause incomplete BIOS update in that case.
