Overview

The AP57 is a high-performance Pentium -based system board that utilizes

the PCI/ISA architecture. It integrates the SiS 5571 PCIset, a super I/O

controller, and a PCI mode 4 enhanced IDE controller with bus master

support to enhance system performance. It has four single in-line memory

module (SIMM) sockets that allow system memory expansion up to a

maximum of 256MB. It also supports 256KB and 512KB pipelined-burst

second-level cache.

One main feature of AP57 is the green power-management function that

extends energy conservation from system components to display monitor. It

complies with the power-saving standards of the U.S. Environmental

Protection Agency (EPA) Energy Star program.

The AP57 board measures 220 mm x 250 mm.
