Overview
Thank you for purchasing Iwill XA100 Ultra DMA 33 Motherboard. This operation manual will
instruct you how to configure and install properly. It contains an overview about the engineering
design and features of this board. Also, this manual provides useful information for later on
upgrade or configuration change. Keep this for your future need.
0.1 Features
This XA100 Ultra DMA 33 motherboard is your best choice for optimizing media rich
performance desktop on the socket 7 processor with the new MMX technology. It incorportes with
ALI Aladdin V PCI set with I/O subsystem that supports for processor external working frequency
up to 100MHz.
To run faster bus speed is a great plus in this XA100 motherboard. It not only can run the 66MHz
bus that Intel claims on all her highest system bus but also built in 75MHz, 83MHz and 100MHz
bus speed as an option for users to take advantage of.
In order to support all the legacy ISA devices well available today, there are 3 ISA slots for great
expansion ability.
The concurrent PCI (PCI 2.1) reduces CPU latencies for smoother video and more realistic audio,
and Universal Serial Bus (USB) technology makes Plug and Play peripheral connections a reality.
Besides, run with faster system memory is another feature on this Pentium EIDE Motherboard to
outperform the whole system performance. It equips with three of the 168-pin DIMM memory
sockets that support the new 3.3V, unbuffered Synchonous DRAM.
The onboard two IDE channels support UltraDMA/33 that enhances the data transfer rate to 33
Mbytes, which is new technology and is compatible with the existing ATA-2 IDE specification.
It fully supports plug and play I/O that contains two high speed serial ports, one ECP/EPP printer
port, up to 2.88 floppy disk port, and keyboard. And the real time clock is used for users to enjoy
the plug and play function. This Pentium EIDE, Ultra DMA 33 motherboard is designed to be
compliant with ATX specification to improve the easy access memory module, long add-on card
support and some of the new features that traditional AT form factor can not achieved.
It is a powerful combination of performance, quality and innovative design to address the need of
today’s market. Current Intel, Cyrix, AMD processors with MMX technology supported, 512K
