AGP slot. This Accelerated Graphics Port (AGP) slot supports 1.5V
AGP4X mode graphics cards for 3D graphical applications.
Flash EEPROM. This 4Mb firmware contains the programmable
BIOS program.
South bridge controller. Referred to as the Intel I/O Controller
Hub 2 (ICH2) of the Intel 845 chipset, this controller provides the
I/O subsystem that allows access to the rest of the system. The
ICH2 integrates I/O functions such as system bus interface, Ultra
ATA/100, Low Pin Count (LPC) interface, Universal Serial Bus
(USB) 1.1 interface, PCI interface, and CNR interface.
SD and MS connectors. These are interfaces for the new
generation memory devices called Secure Digital (SD) memory
card and Memory Stick (MS).
RAID Ultra ATA/100/66/33 interfaces. These dual-channel
connectors support Ultra ATA/100/66/33 hard disk drives in RAID 0/
RAID 1 configurations.

ASUS ASIC. This chip performs multiple system functions that
include hardware and system voltage monitoring, IRQ routing,
among others.
DIP switches. This 10-switch Dual Inline Package (DIP) allows you
to set the CPU frequency.
AGP warning LED. Serving as a smart burn-out protection for the
motherboard, this red LED lights up if you plug in any 3.3V AGP
card into the AGP slot. When this LED is lit, there is no way you
can turn on the system power even if you press the power button.
Onboard LED. This onboard LED lights up if there is a standby
power on the motherboard. This LED acts as a reminder to turn off
the system power before plugging or unplugging devices.
CNR slot. This slot is specifically designed for the Communications
and Networking Riser (CNR) card. The CNR supports V.90 analog
modem, six-channel audio, HPNA, USB Hub, and the 10BASE-T/
