Operation is subject to the following two conditions: • • This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
I. ASUS ASMM I. ASUS ASMM Introduction Introduction The ASUS ASMM (System Monitoring Module) allows you to monitor the system temperature, fan speed, and voltages to enhance system stability. IMPORTANT! If your motherboard is equipped with the LM78 chipset, your system will report a warning since both LM78s (motherboard and ASMM’s) use the same I/O address (0x0290), which is necessary for the LDCM software to function. Future BIOS will automatically disable the onboard LM78 if the ASMM is detected.

I. ASUS ASMM I. ASUS ASMM System/Cabling 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.
I. ASUS ASMM I. ASUS ASMM Programming Interface Programming Interface LM 78 The LM78 address is fixed on I/O port 0x0290–0x0297 by default, as follows: 0x0290 Power On Self Test codes from ISA bus 0x0294 Power On Self Test codes from ISA bus 0x0295 The LM78 internal Address register 0x0296 Data register For the relative programming interface, refer to the N.S. LM78 data sheet. Automatic Server Restart Four I/O ports are defined in this revision and are allocated on I/O space 0x0298– 0x029F by default.
I. ASUS ASMM I. ASUS ASMM Programming Interface bit 1 Mode select B “1” ASR is in normal mode. The ASR can be enabled after a special I/O write sequence is executed. “0” ASR is under test mode. bit 0 System in secure mode. A “0” indicates the system is now under secure mode. A “1” depicts the system is now free for control. Write bit 7:3 Reserved. bit 2 Mode select A Writing a “1” will select secure mode while it will be enabled after a special I/ O write sequence is executed.
I. ASUS ASMM I. ASUS ASMM Programming Interface ASR Enable/Disable Sequence and Test The ASR function will be enabled by consecutively writing three I/O writes to the ASR enable/disable register with data pattern of xxxx_0001b. After these I/O writes are executed, bit 3 of the ASR status/control register will be set to “1” and bit 4 of the ASR status/control register will become “0” when there is no I/O write to the ASR trigger register within a pre-specified period of time.
