AMI BIOS
The AMI BIOS (basic input-output system) resides in the flash ROM
chip. This contains the program that performs the power-on self-
tests (POST) upon booting. During POST, this program activates the
peripheral devices, tests onboard memory, and prepares the system
for operation. Chapter 4 gives more information on the AMI BIOS.
Expansion Slots
The board expansion slots consist of three ISA-AT and three PCI
slots. These expansion slots are the parallel bars on the system
board. There are rows of golden pins inside each slot that serve as a
clutch to secure the contacts of expansion boards. Chapter 2 tells
how to install the expansion boards.
DRAM Sockets
The system board has four 72-pin DRAM sockets that expand system
memory to a maximum of 128 MB. These sockets accept single-
and double-density single in-line memory modules (SIMMs) that
support either Fast Page or Extended Data Out (EDO) modes.
Chapter 2 discusses the different memory configurations available.
Second-level Cache
The system board comes with an onboard 256-KB pipelined-burst
cache. This enables AP55CS to enhance the performance of a
Pentium system.
