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 three 168-pin DIMM sockets
support up to 3GB using unbuffered ECC or non-ECC PC100/133
SDRAM DIMMs.
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).
Super I/O chipset. This Low Pin Count (LPC) interface provides
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.
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.
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.
Flash EEPROM. This 2Mb firmware contains the programmable
BIOS program.
DIP switches. This 10-switch Dual Inline Package (DIP) allows you
to set the CPU external frequency.
