Chapter 1 System Board
1.1

Features

This high-performance system board supports the Intel Pentium II CPU running at 233 up
to 450 MHz. Integrated with the Intel 440BX system controller, which consists of the PCI
controller and the PCI/ISA IDE accelerator (PIIX4), the system combines the new
generation of Pentium II power with unmatched graphics performance.
The system controller host bus interface supports a Pentium II processor with 66 or 100
MHz external front side bus frequency. It also provides support for ECC synchronous
DRAM (SDRAM) 168 pin DIMMs.
The PIIX4 is a multifunction PCI device controller implementing system functions
including PCI IDE and universal serial bus (USB) host/hub. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.
The system board utilizes both the ISA and the PCI local bus architecture. Two ISA, five
PCI bus slots (including one PCI/ISA shared slot), and one AGP slot reside on the system
board.
Three memory banks composed of 168-pin dual inline memory module (DIMM) sockets
support a maximum system memory of 384 MB using 128-MB DIMMs.
The system board also supports the USB (Universal Serial Bus) interface, and other
standard features such as two UART NS16C550 serial ports, one enhanced parallel port
with an Enhanced Parallel Port (EPP)/Extended Capabilities Port (ECP) feature, a diskette
drive interface, and two embedded hard disk interfaces.
