System Board 1-1
1.1 Features
This high-performance system board supports the Intel Pentium II CPU
running at 233 up to 350 and 400 MHz. Integrated with the Intel 440BX
system controller, which consists of the PCI/AGP controller and the
PCI/ISA IDE accelerator (PIIX4), the M11E combines the new
generation of Pentium II power with unmatched graphics performance.
The PCI/AGP controller host bus interface supports a Pentium II
processor with 66 or 100 MHz bus frequency. It also provides a 72-bit
DRAM that supports synchronous DRAM (SDRAM) DIMMs. The
PCI/AGP controller introduces a new technology, which is the
Accelerated Graphics Port (AGP) interface. Supporting up to 133 MHz
data transfer speed, the AGP interface boosts graphics performance.
The PIIX4 is a multifunction PCI device controller implementing system
functions including PCI IDE, universal serial bus (USB) host/hub, and
enhanced power management. 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 board to allow installation of either
master or slave devices.
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 sockets only supports SDRAM-type DIMM.
