 266/300/300A/333MHz CeleronTM processor
System Memory
The system board supports 8MB to 384MB using unbuffered
SDRAM or EDO memory. It is equipped with three 168-pin DIMM
sockets using x64/x72 EDO (50/60ns) or SDRAM (10/12/13ns),
3.3V. It also supports ECC (uses x72 DRAM).
Expansion Slots
The system board is equipped with 1 dedicated AGP slot, 3
dedicated PCI slots, 1 dedicated 16-bit ISA slot and 1 shared PCI/
ISA slot. All PCI and ISA slots are bus masters.
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 inventor y, maintenance and troubleshooting of
computer systems easier.

Automatic CPU Fan Off
The CPU fan will automatically turn off once the system enters the
Suspend mode. This prevents system overheat and prolongs fan life.
Dual Function Power Button (ATX power supply only)
Depending on the setting in the BIOS setup, this switch will allow
your system to enter the Soft-Off or Suspend mode.
External Modem Ring-on (ATX power supply only)
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. This feature supports external modem
only.

Introduction

RTC Timer to Power-On the System (ATX power supply only)
The RTC installed on the system board allows your system to
automatically power-on on the set date and time.
Wake-On-LAN Ready (ATX power supply only)
The Wake-On-LAN function allows the network to remotely wake
up a Soft Power Down (Soft-Off) PC. Your LAN card must support
the remote wakeup function.
Important:
The 5VSB power source of your power supply must support
720mA (minimum).
Wake-On-Keyboard/Wake-On-Mouse (ATX power supply only)
This function allows you to use the keyboard or mouse to power-on
the system. Refer to sections 2.4 (chapter 2) and 3.9 (chapter 3) for
more information.
Important:
The power button will not function once a keyboard password
has been set in the KB Power On Password field of the
Integrated Peripherals setup. To power-on the system, you must
type the password then press <Enter>.
ACPI (ATX power supply only)
The system board is designed to meet the ACPI (Advanced
Configuration and Power Interface) specification. ACPI has energy
saving features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management.
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive.
