Overview
The AX53 is a high-performance Pentium®-based system board that utilizes the PCI/ISA architecture. It has four single in-line memory module (SIMM) sockets that allow memory expansion up to a maximum of 512 MB. It also comes either with 256-KB or 512-KB pipelined-burst cache.
To further enhance system performance, the board also integrates the Intel 430HX PCIset, a super I/O controller and a PCI mode 4 enhanced IDE controller with bus master support.
One main feature of AX53 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 AX53 board measures 284 mm x 208 mm (11.2 in. x 8.2 in., mini-ATX form).
