Special Tip for User's Reference Only
HOT-681 mainboard provides a special
Jumper JP4
to overspeed your 66 MHz based Intel PPGA Celeron
processor to 100 MHz when jumper group JP6 set to
MANUAL.
Normally, CPU Host Clock 100 ~ 133 MHz are not
available for 66 MHz based processor no matter Soft-
Configure or Hard-Configure.
But, when pull out mini jumper from JP4 (let it open),
the user can Hard-Configure your 66 MHz based
processor to 100 MHz based. For example, overspeed
your 333 MHz (66 MHz x 5) PPGA Celeron to
400 MHz (100 x 4) or more.
