Special Tip for User's Reference Only
HOT-685V mainboard provides a special
Jumper J10
to overspeed your 66 MHz based
Intel PPGA Celeron processor to 100 MHz.
Normally, CPU Host Clock 100 ~ 150 MHz are
not available for 66 MHz based processor.
But, when pull out mini jumper from J10 (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.

Flash EEPROM Vpp - JP7
HOT-685V mainboard supports two types of Flash EEPROM : 5 volt and 12 volt. By
setting up jumper JP11, the main board can use both 5V or 12V flash EEPROM with new
system BIOS files as they come available.
