Auto Fan Off: The system fans powers off automatically even in sleep mode. This function reduces both energy consumption and system noise, and is an important feature in implementing silent PC systems. Dual Function Power Button: Pushing the power button for less than 4 seconds when the system is in the working state places the system into one of two states: sleep mode or soft-off mode, depending on the BIOS or OS setting (See PWR Button < 4 Secs in 4.5 Power Menu). When the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting. Fan Status Monitoring and Alarm: To prevent system overheat and system damage, the CPU and system fans can be monitored for RPM and failure. All fans are set for its normal RPM range and alarm thresholds. Power LED (requires ACPI OS support): The power LED indicates the system status. Remote Ring-On (requires modem): This allows a computer to be turned on remotely through an internal or external modem. With this benefit on-hand, users can access vital information from their computers anywhere. Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPUs internal thermal diode (on Pentium III and Celeron) to prevent system overheat and system damage. Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable voltage to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management. Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection.

3.5.1 General DIMM Notes
DIMMs that have more than 18 chips are not supported on this motherboard. ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability. BIOS shows SDRAM memory on bootup screen. Single-sided DDR DIMMs come in 64, 128, and 256MB; double-sided come in 128, 256, and 512MB.

WARNING! Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard. IMPORTANT: Ribbon cables should always be connected with the red stripe to Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives. Check the connectors before installation because there may be exceptions. IDE ribbon cable must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

9) Floppy Disk Drive Connector (34-1 pin FLOPPY) This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plugs on the other end to the floppy drives. (Pin 5 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 5 plugged).
NOTE: Orient the red markings on the floppy ribbon cable to PIN 1
10) Primary (Blue) / Secondary IDE Connectors (40-1 pin IDE1/IDE2) These connectors support the UltraDMA/100/66 IDE hard disk ribbon cable supplied with the motherboard. Connect the cables blue connector to the primary (recommended) or secondary IDE connector, then connect the gray connector to the UltraDMA/100/66 slave device (hard disk drive) and the black connector to the UltraDMA/100/66 master device. It is recommended that non-UltraDMA/ 100/66 devices be connected to the secondary IDE connector. If you install two hard disks, you must configure the second drive as a slave device by setting its jumper accordingly. Refer to the hard disk documentation for the jumper settings. BIOS supports specific device bootup (see 4.6. Boot Menu). If you have more than two UltraDMA/100/66 devices, purchase another UltraDMA/100/66 cable. NOTES: 1. Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector. This prevents incorrect orientation when you connect the cables. 2. The hole near the blue connector on the UltraDMA/100/66 cable is intentional. TIP: You may configure two hard disks to be both Masters with two ribbon cables: one for the primary IDE connector and another for the secondary IDE connector. IMPORTANT: For UltraDMA/100/66 IDE devices,use a 40-pin 80-conductor IDE cable. The UltraDMA/66 cable included in the motherboard package also supports UltraDMA/100.

Once a smart card reader is configured, set up the Smart Manager software utility for boot up or always on system security.
6.1.1 Setting Up Smart Manager
Connect the smart card reader to the A7V266; (refer to Section 3.8.13 in Hardware Setup for the connector location.) Boot up the PC and enter BIOS (press <del>) to change the configuration to accept smart card hardware: in the Advanced BIOS menu select the I/O Device Configuration sub-menu, go to UART2 and select Smart Card Read, save and exit.
Finish booting up. Insert the ASUS Support CD and click on the selection: Winbond Smart Manager Application. The auto-installer prompts to install the Base Components and after doing show displays a readme file. Next, immediately install the Smart Card Driver Library as prompted. Finally, install the Winbond Smart Manager application as prompted.

84 The auto-installer implements all of the drivers, base components and displays the Winbond Smart Manager program groups. Restart. Windows should auto-detect the smart card reader and install its system drivers.
NOTE: Do not install system components or Winbond applications unless you install a smart card reader, (see page 7). Smart card system software components support various types of smart card applications; all system components are compatible with Windows 98, ME and 2000. However, the Windbond Smart Manager application is readily compatible only with Windows 98 and ME.
After installing the software, start Windbond Smart Manager for the first time: select the Programs menu from the Start bar and select the Windbond program group. When you click the program application, an icon is created for the Logon Smart Card software in the bottom right hand corner of the screen.
