Overview
AX3L is a new generation Socket 370 based system board that utilizes Intel
82440LX AGPset on ATX PCI/ISA platform. This AGPset is designed for
Pentium II CPU, and supports new architectures such as high speed AGP
graphic port, SDRAM, Ultra DMA/33, Bus master IDE and USB port. It has
three Dual in-line Memory Module (DIMM) that allow to install SDRAM
memory and expand up to a maximum of 768MB. Since the cache is on the
Pentium II CPU card (connector SLOT1), there is no second level cache
onboard Also, AX3L uses 2M bit Flash ROM BIOS to reserve for future new
functions.
Not only above features, AX3L also implements many special features as
following.
Jumper-less Design Celeron PPGA VID signal and SMbus clock generator
provide CPU voltage auto-detection and allows user to set CPU frequency
through CMOS setup, no jumper or switch is needed. The correct CPU
information is saved into EEPROM, with these technologies, the
disadvantages of Pentium base jumper-less design are eliminated. There will
be no worry of wrong CPU voltage detection and no need to re-open the
housing if CMOS battery loss. The only jumper left is to clear CMOS, which is
a safety hook if you forget the password.
Battery-less AX3L implements EEPROM and special circuit (patent applied)
that allows you to save your current CPU and CMOS Setup configurations
without the need of battery. The RTC (real time clock) can also keep running
as long as power cord is plugged. If you lose your CMOS data by accident, you
can just reload the CMOS configurations from EEPROM and the system will
recover as usual.
APM 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
