ATX 12V connector. This power connector connects the 4-pin 12V
1
plug from the ATX 12V power supply.
CPU socket. A 478-pin surface mount, Zero Insertion Force (ZIF)
2
socket called mPGA478. This socket accommodates the Intel
Pentium
North bridge controller. This SiS650 controller integrates a high
3
performance host interface for the Intel Pentium 4 processor, a
memory controller, an AGP interface, and SiS MuTIOL technology.
ATX power connector. This 20-pin connector connects to an ATX
4
+12V power supply. The power supply must have at least 1A on the
+5V standby lead (+5VSB).
DDR DIMM sockets. These two 184-pin DIMM sockets support up
5
to 2GB using unbuffered non-ECC PC2100/1600 DDR DIMMs.
IDE connectors. These dual-channel bus master IDE connectors
6
support up to four Ultra DMA/100/66, PIO Modes 3 & 4 IDE
devices. Both the primary (blue) and secondary (black) connectors
are slotted to prevent incorrect insertion of the IDE ribbon cable.
South bridge controller. Referred to as the SiS961 MuTIOL Media
7
I/O, this controller integrates the audio controller with AC'97
Interface, Ethernet MAC, Dual Universal Serial Bus Host
controllers, IDE Master/Slave controllers, and the MuTIOL Connect
to PCI Bridge.
ASUS ASIC. This chip performs multiple system functions that
8
include hardware and system voltage monitoring.
Onboard LED This green indicator light informs the user that
9
power is being supplied to the board.
Floppy disk connector. This connector accommodates the
10
provided ribbon cable for the floppy disk drive. One side of the
connector is slotted to prevent incorrect insertion of the floppy disk
cable.
Flash EEPROM. This 2Mb firmware contains the programmable
11
BIOS program.
Super I/O controller. This Low Pin Count (LPC) interface provides
12
the commonly used Super I/O functionality. The chipset supports a
high-performance floppy disk controller for a 360K/720K/1.44M/
2.88M floppy disk drive, a multi-mode parallel port, two standard
compatible UARTs, a Standard Infrared (SIR), one MPU-401 UART
mode compatible MIDI/game port, and a Flash ROM interface.
PCI slots. These three 32-bit PCI 2.2 expansion slots support bus
13
master PCI cards like SCSI or LAN cards with 133MB/s maximum
throughput.
