HOT-675 mainboard provides a Jumper group JP10 to set CPU Speed configure by BIOS or by
hardware jumper.
By inserting jumper pack on Row B-C group, the user can Soft-Configure the
CPU Host Clock
and
CPU Clock Ratio
from BIOS.
By removeing jumper pack from Row B-C group and inserting mini jumpers on Row A-B group
properly, the user can configure the CPU Clock Ration (multiplier) manually.
Note
: 73, 83 MHz are for 66 MHz based and 103 ~ 133 MHz are for 100 MHz based processor over-
clock usage, it is not a recommended general practice.

Special Tip for User's Reference Only
HOT-675 mainboard provides a special
Jumper J19
to overspeed your 66 MHz based Pentium II processor
to 100 MHz.
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 J19 (let it open),
the user can Hard-Configure your 66 MHz based
processor to 100 MHz based. For example, overspeed
your 266 MHz (66 MHz x 4) Celeron to
300 MHz (100 x 3) or more.
