Remark : x : Don't care
* : For the single-VCC required CPUs (e.g. Intel P54C, AMD-SSA/5-xxAB?,
AMD-SSA/5-xxAC?, AMD-SSA/5-xxAF?, Cyrix 6x86 ... etc.)
** : For a part of the dual-VCC required CPUs (e.g. Intel P55C-166, Cyrix M2,
AMD-SSA/5-xxAK? ... etc.)
*** : For a part of the dual-VCC required CPUs (e.g. Intel P55C-200, Cyrix M2,
AMD-SSA/5-xxAH?, AMD-SSA/5-xxAJ? ... etc.)
Note : For the detailed CPU-VCC requirement, please inquire of your CPU supplier.
(C) JP11 Clear CMOS button
Pin #
Function
open Normal operation
short Clear CMOS ( Note : Don't forget to open this jumper after 3 seconds. )
Note : Depends on different brand of RTC Module (U20 or U21), there are two ways to clear
CMOS, (1) while power-on, (2) while power-off, the following is a list for reference :
(1) while power-on : BENCHMARQ / bq3287AMT, SGS / M48T86,
(2) while power-off : VIA / VT82885N, ODIN / OEC12C885 / OEC12C887A,
DALLAS / DS12887A.
