Chapter 1
Overview
The AX5TC is a high-performance Pentium¿ø»~! '|¥…'w‚q ¯¡C -based
system board that utilizes the PCI/ISA architecture and ATX form factor. It
integrates the Intel 82430TX PCIset, an Ultra I/O controller, and a PCI mode 4
enhanced IDE controller with bus master and Ultra DMA/33 to enhance system
performance. It has 512KB pipeline-burst second-level cache onboard and
support three Dual in-line memory modules (DIMM) that allow to mix EDO
and SDRAM memory and expansion up to a maximum of 256MB. AX5TC uses
2M bit Flash ROM BIOS to reserve for future new functions.
Not only above features, AX5TC implements most advanced technology such
as High-quality DIP switch, CMOS and RTC battery-less backup, Synchronous
switching regulator, CPU thermal protection, Fan monitoring, System voltage
monitoring, Modem Wake Up and Suspend to Hard Drive.
In addition, AX5TC also implements many special features as following.
Suspend To Hard Drive "Immediately" turns on system and goes back to the
original screen before power down. You can resume your original work directly
from hard disk without go through the Win95 booting process and run your
application again. Suspend to Hard Drive saves your current work (system
status, memory image) into hard disk. Note that you have to use VESA
compatible PCI VGA, Sound Blaster compatible sound card with APM driver,
for Suspend to Hard Drive to work properly.
0V Modem Card 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 AX5TC and MP56
internal modem card implement special circuit (patent applied) to make sure
the modem card work properly without any power.
