I. ASUS ASMM
System Control
Reset Button: Hard reset enable/disable
Keylock: keyboard lock/unlock
ASR: Enable, disable, and test
ASR period: ASR period selection through mini-jumper (30/120/240/330 seconds)
Chassis Intrusion: As this status will be backup through battery, one can clear the
memorization of intrusion circuit.
System Notification
The system can be notified when the voltage/temperature/fan speed exceeds the
predefined thresholds. The notification mechanism can be as simple as polling or
through SMI#/IRQ service routine, depending on the programming of LM78. Five
ISA IRQs can be selected (IRQs 3, 4, 5, 6, 7) through hardware jumper.

ASMM Color-Coded Cabling
These connections are classified into 3 categories: chassis intrusion, fan monitor,
and server monitor.
Chassis intrusion: Chassis intrusion permits the activation of a user-installed alarm.
One 3-wire cable supports the external customized chassis intrusion alarm. The pin
definitions are: RED (battery power), YELLOW (intrusion signal), and BLACK
(ground). The external intrusion signal should be open-drained.
Fan monitor: The fan monitor provides power for up to 3 fans while monitoring
the connected fans’ rotation through the specially designed tachometer. Three 3-
wire cables are used to extend the length of each fan connection. The pin definitions
are: YELLOW (tachometer signal), RED (+12V), and BLACK (ground).
Server monitor:
The server monitor contains many signals that can be monitored
and controlled through the software. The server monitor signals are: CPU voltage
ID for Pentium II processor (N.A. in P/I-P65UP8), key lock and reset, CPU1 and
CPU2 Vcore (N.A. in P/I-P65UP8), +3.3V, I2C bus (N.A. in P/I-P65UP8), and CPU1
and CPU2 thermister (N.A. in ASMM), EXTSMI#. One 20-wire ribbon cable is
used. The red stipe indicates pin 1.
NOTE: If you want to test the security mode, the KEYLOCK and RESET connec-
tions must be correct. If the position of the reset signal is wrong, the reset inhibit
function may not work.
