FCPU Clock Ratio
This setup option will automatically assign by CPU detection.
For Willamette CPU:
8X~23X default: 14X
For C-Stepping P4:
8X,10X~24X default: 15X
For Northwood CPU:
12X~24X default: 16X
The option will display " Locked" and read only if the CPU ratio is not changeable.
FCPU Host Clock Control
Note: If system hangs up before enter CMOS setup utility, wait for 20 sec for times out reboot . When
time out occur, system will reset and run at CPU default Host clock at next boot.
