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.

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
