1.3 System Board Parts
1.3.1 Microprocessor
The AP5V system board uses an Intel Pentium (3.3V) Processor running at 75,
90, 100, 120, 133, 150, 166, or 200 MHz. Chapter 2 gives details on how to
install and upgrade a processor.
1.3.2 ASICs
The ASICs (application-specific integrated circuits) onboard are the Intel
82437VX, Intel 82438DX, and the Intel 82371SB. The Intel 82437VX functions
as the host/PCI bridge, DRAM and second-level cache controller. The Intel
82438DX serves as the memory controller data path. The Intel 82371SB acts
as the ISA/PCI bus bridge that translates the PCI bus cycles into ISA bus
cycles or vice-versa. It also functions as the universal serial bus controller and
supports Fast IDE and PCI/ISA master/slave interfaces.
1.3.3 BIOS
The board supports the AMI basic input-output system (BIOS). The BIOS is a
program that performs the power-on self test (POST) upon booting. During
POST, this program activates the peripheral devices, tests onboard memory
and prepares the system for operation. For more information on AMI BIOS,
see Chapter 3.
