Overview
MX3ZA is a new generation Socket 370 based system board that utilizes Intel
82440ZX AGPset on Micro ATX PCI/ISA platform. This AGPset is designed
for Celeron PPGA CPU, and supports new architectures such as a high speed
AGP graphic port, SDRAM, Ultra DMA/33, Bus Master IDE and USB port. It
has two Dual in-line Memory Module (DIMM) slots that allow to install
SDRAMs and expand up to a maximum of 256MB. Also, MX3ZA uses a 2M bit
Flash ROM BIOS to reserve for future new functions.
In addition to the above features, MX3ZA also implements many special
features as follows.
Jumper-less Design Celeron VID signal and SMbus clock generator provide
CPU voltage auto-detection and allows the user to set the CPU frequency
through the CMOS setup, therefore no jumpers or switches are used. The
correct CPU information is saved into the EEPROM. With these technologies,
the disadvantages of the Pentium based jumper-less designs are eliminated.
There will be no worry of wrong CPU voltage detection and no need to re-open
the housing in case of CMOS battery loss. The only jumper left is to clear the
CMOS, which is a safety hook if you forget the password.
Battery-less Motherboard This motherboard implements EEPROM and a
special circuit (patent applied) that allows you to save your current CPU and
CMOS Setup configurations without the need of a battery. The RTC (real time
clock) can also keep running as long as the 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
VESA compatible PCI VGA, Sound Blaster compatible sound card with APM
driver, for Suspend to Hard Drive to work properly.
