Features

This high-performance system board supports the new Intel Pentium
Pro CPU running at 150/180/200 MHz. Designed to work with Intel
chipsets composed of PCI bridge, memory controller, data bus
accelerator, and data buffers, the CPU carries a new generation of
power not present in its predecessors. The CPU also incorporates the
first-level (L1) and second-level (L2) caches, the advanced peripheral
interrupt controller (APIC), and the system bus controller.
The system board utilizes both the ISA and the PCI local bus
architecture. Three ISA and four PCI bus slots reside on the board to
allow installation of either master or slave devices.
The board has three memory banks composed of two 72-pin SIMM
sockets each that support a maximum system memory of 384 MB
using 64-MB SIMMs. The SIMM sockets support both EDO and fast-
page mode SIMMs.
A 50-pin Fast SCSI-II and a 68-pin Wide SCSI interface come with
the system board to connect SCSI devices. Standard I/O features
such as two enhanced IDE drive interfaces, two serial interfaces, one
parallel port interface, a diskette drive interface, and PS/2 mouse and
keyboard connectors reside on the system board.
