Onboard Voltage Regulators
HOT-617 mainboard is designed with onboard voltage regulator to
provide power for Pentium™ Pro processor, external VRM wasn't
needed.
Pentium™ Pro processors required different voltages. Current
processors (marked "Pentium™ Pro") support VID and will
automatically adjust the voltage regulator so that no jumper
settings are required and provided on
HOT-617.
HOT-617 doesn't support older Pentium Pro processors
without VID supported
.

This jumper clears the CMOS data stored in the ITE 8680 Giga I/O chip. To clear the
CMOS data please follow list steps:
1) Turn off the PC,
2) Remove the jumper cap from Pin 1-2,
3) Insert the jumper cap on Pin 2-3 for a while
4) Remove the jumper cap from Pin 2-3,
5) Reinsert the jumper cap on Pin 1-2,
6) Turn on the PC.
