Overview
AX59 Pro is a high-performance Pentium ® -based system board that utilizes
VIA MVP3 AGPset on ATX PCI/ISA platform. This motherboard supports new
architectures such as high speed AGP, SDRAM, Ultra DMA/33, Bus master
IDE and USB port. It has 512KB or 1MB (optional) pipelined-burst second-
level cache onboard and support two single in-line memory module (SIMM)
plus three Dual in-line memory module (DIMM) that allows to mix EDO and
SDRAM memory and expansion up to a maximum of 1GB.
Not only above features, AX59 Pro implements most advanced technology as
following.
Zero Voltage Modem Wake Up In conjunction with ATX soft power On/Off, it
is possible to have system totally power off and wakeup to automatically
answer a phone call such as answering machine or to send/receive fax. The
most important break through is not only external box modem but also internal
modem card can be used to support Modem Wake Up. The AX59 Pro and
MP56 internal modem card implement special circuit (patent applied) to make
sure the modem card work properly without any power.
LAN Wake Up This feature is very similar as Modem Wake Up, but it is through
local area network. To use LAN Wake Up function, you must have a network
card that supports this feature and also need to install a network management
software.
RTC Wake Up Timer The Wake Up Timer is more like an alarm, which wakes
up and power on your system at a pre-defined time for specific application. It
can be set to wake up everyday or on specific date within a month. The
date/time accurate is second.
High Efficient Synchronous Switching Regulator Most of the current
switching designs are Asynchronous mode, which from the technical point of
view, still consumes very high power as well as heat. AX59 Pro implements
high efficient synchronous switching design that the temperature of MOS FET
is far less than Schottky diode of Asynchronous design.
