Expansion Slots The system board is equipped with 1 dedicated PCI slot, 5 dedicated 16-bit ISA slot and 1 shared PCI/ISA slot. All PCI and ISA slots are bus masters. Disk-On-Chip Optional M-system up to 144Mbytes or above. Desktop Management Interface (DMI) The system board comes with a DMI 2.0 built into the BIOS. The DMI utility in the BIOS automatically records various information about your system configuration and stores these information in the DMI pool, which is a part of the system board's Plug and Play BIOS. DMI, along with the appropriately networked software, is designed to make inventory, maintenance and troubleshooting of computer systems easier. Refer to Chapter 4 for instructions on using the DMI utility.

BIOS • Award BIOS, Windows 95/98 Plug and Play compatible • Supports DMI 2.0 function • 2 MBit flash EPROM for easy BIOS upgrades • Includes NCR 810 SCSI BIOS 1.1.2 System Health Monitor Functions The system board is capable of monitoring the following “system health” conditions. • Monitors processor/system temperature and processor overheat alarm • Monitors 1.5V/3.3V/±5V/±12V/VCORE voltages and failure alarm Introduction 1 9 • Monitors processor/chassis fan speed and failure alarm • Automatic processor/chassis fan control • Read back capability that displays accurate temperature, voltage and fan speed • Watchdog timer function 1.1.3 Intelligence Automatic CPU/Chassis Fan Off The CPU and chassis fans will automatically turn off once the system enters the Suspend mode. Dual Function Power Button Depending on the setting in the BIOS setup, this switch will allow the system to enter the Soft-Off or Suspend mode. Watchdog Timer The Watchdog Timer function allows your application to regularly “clear” the system at the set time interval. If the system hangs or fails to function, it will reset at the set time interval so that your system will continue to operate. Refer to “Watchdog Timer Select” in the Integrated Peripherals setup of the Award BIOS. External Modem Ring-on The Modem Ring-on feature allows the system that is in the Suspend mode or Soft Power Off mode to wake-up/power-on to respond to incoming calls. Note: This feature supports external modem only. RTC Timer to Power-on the System The RTC installed on the system board allows your system to automatically power-on on the set date and time
