CPU socket. A 478-pin surface mount, Zero Insertion Force (ZIF)
socket called mPGA478 B. This socket accommodates the Intel
®
Pentium
®
4 478/Northwood Processor with 400MHz system bus.
North bridge controller. This controller called the Intel Memory
Controller Hub (MCH) is one of the two major components of the
Intel 845 (Brookdale) chipset. The MCH along with the south bridge
Intel I/O Controller Hub 2 (ICH2) are interconnected through the
Intel proprietary Hub interface. The MCH provides the processor
interface, system memory interface, AGP interface, and Hub
Interface.
SDRAM DIMM sockets. These two 168-pin DIMM sockets support
up to 2GB using unbuffered ECC or non-ECC PC133 SDRAM
DIMMs.
Floppy disk connector. This connector accommodates the
provided ribbon cable for the floppy disk drive. One side of the
connector is slotted to prevent incorrect insertion of the floppy disk
cable.
ATX power connector. This 20-pin connector connects to an ATX
12V 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 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.
AGP slot. This Accelerated Graphics Port (AGP) slot supports 1.5V
AGP 4X mode graphics cards for 3D graphical applications.
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.
ASUS ASIC. This chip performs multiple system functions that
include hardware and system voltage monitoring, IRQ routing,
among others.
