DDR DIMM sockets. These three 184-pin DIMM sockets support up to 3GB
3
system memory using unbuffered non-ECC PC2100/1600 DDR DIMMs.
(Note: PC2700 maximum to 4 banks only. PC3200 maximum to 2 banks
only. Visit the ASUS website [www.asus.com] for the latest qualified DDR400
module list.)
ATX power connector. This 20-pin connector connects to an ATX +12V
4
power supply. The power supply must have at least 1A on the +5V standby
lead (+5VSB).
IDE connectors. These dual-channel bus master IDE connectors support
5
up to four Ultra DMA133/100/66, 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.

motherboard. This LED acts as a reminder to turn off the system power
before plugging or unplugging devices.
Super I/O controller. This Low Pin Count (LPC) interface provides the
10
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 and
a Flash ROM interface.
11 PCI slots. These six 32-bit PCI 2.2 expansion slots support bus master
