Step 4. Set the CPU Frequency
This Motherboard does not use any jumpers to set the CPU frequency; the CPU settings
can be changed through the BIOS [SOYO COMBO SETUP]. Please refer to Chapter 3
“Quick BIOS Setup” for details on setting the Coppermine
TM
processor frequency.
Step 5. Set JP9 for 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.
