[. . . ] Procedures for disabling the motherboard's LM78: 1. Create a bootable disk by formatting a floppy disk with system files. Copy the PCI control program PCICFG. EXE to the disk 3. Copy the DOS utility DEBUG. COM to the disk (NOTE: DEBUG. COM must be the same version as the DOS version on the disk otherwise, it will not run) 4. With the disk inserted, restart the system and press DELETE to enter BIOS setup. Adjust the BIOS boot sequence to A:, C: (that is, boot from floppy first). NOTE: Ignore the next hardware monitor error from the LM78 conflict. Under the appropriate prompt signs, type the following: A> BUS00> BUS00> A> > xxxx:0100 xxxx:01yy > PCICFG <ENTER> WD 1 3 60 00670290 <ENTER> (disables the motherboard's LM78) Q <ENTER> (exits the PCI control program) DEBUG <ENTER> A <ENTER> int 19 <ENTER> <ENTER> (then remove the disk from the floppy drive) G <ENTER> ASUS ASMM User's Manual 7 I.

ASUS ASMM BUS: 8-bit ISA bus Battery: Lithium battery, 210mA/hour Thermal Monitoring: Onboard temperature sensor Voltage Monitoring: +12V, -12V, +5V, -5V, +3. 3V (+3. 3V needs external cable) Fan Speed Monitoring: 3 tachometers are provided to detect fan speed as low as 660rpm(needs cooling fan with extra signal line) Chassis Intrusion Monitoring: Optical chassis detection circuit is built-in (external intrusion detection connector is also provided) Security Mode: Keyboard lock/unlock, Reset enable/disable (requires Feature cable) Automatic Server Reset/Restart: Server can be hard reset after a system hang is detected (requires Feature cable) Mechanical: Half-length ISA card (length: 10. 3cm, height: 8. 8cm) Connectors 20-pin external Feature connector for ASUSTeK SMH (Server Monitor Header) 5-pin external keylock connector 2-pin external reset connector 5-pin keylock panel connector 2-pin reset panel connector 3-pin extended fan connectors I. ASUS ASMM Specifications/System 9 Server Monitor Card Specifications System Monitor Voltages: +5V, -5V, +12V, -12V, +3V Temperature: Card temperature Tachometer: 3 fan speed detectors Chassis Intrusion: Onboard Photo-resistor and Chassis intrusion external connector ASR Reset Status: Under ASR (Automatic Server Restart) Test mode, one can access the status of ASR RESET signal while no real system reset will be active. ID: For future upgradability, a card rev. ID is provided to enable the software to identify the card and adapt for it. ASR Status: One can recognize whether the ASR function is enabled or disabled. ASUS ASMM User's Manual 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. ASUS ASMM System/Cabling 10 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. Because ASR needs a much longer time to be reset, this bit should be polled by the BIOS/application before it can be accessed. A "0" indicates the ASR is under reset such that the BIOS/application must wait until it becomes a "1". [. . . ] After the ASR function is enabled, consecutively writing three I/O writes to the ASR enable/disable register with data pattern "xxxx_0001" can disable the ASR function. It can be verified by reading bit 3 of the ASR status/control register to check if it has changed "0". Otherwise, the SMC card is malfunctioning. ASUS ASMM Programming Interface 13 ASR Enable/Disable Sequence and Test Secure Mode Enable/Disable Sequence The system will enter secure mode only when bit 2/Mode Select A of the ASR status/control register is set to "1", then two consecutive I/O writes to the ASR enable/ disable register with data pattern "xxxx_0001" and then another consecutive I/O write to the ASR trigger register are completed.
