AIR BUS -

There is a new interface designed on this mainboard - the AIR Bus ( CN25 ). The
AIR Bus is designed on the mainboard which will give many amazing features to
the PC system. One of the most significant and immediate feature from the AIR
Bus is the "Portable BIOS" device. The Portable BIOS" is an intelligent
device which can be connect to the AIR Bus and it will rescue the system BIOS
from virus attack and BIOS data lost.
Why AIR Bus?
Most modern mainboards use the flash ROM as the storage device to store the
system BIOS. Since the flash ROM is the programmable device and the data stored
in the flash ROM can be destroyed easily. Before we start to introduce how AIR
bus works in your PC system, please refer to the following for the potential risk
which you may found with the programmable flash ROM:
1. SYSTEM BIOS CAN BE KILLED BY VIRUS
There was a virus called CIH virus and it made users start to aware that the
virus could also make serious damage to the mainboard. Such virus will kill the
system BIOS and make PC system failed to work. Unfortunately, there is no
perfect anti-virus software which will prevent the system BIOS from virus
attack. Once the system BIOS is killed by the virus, you will be unable to start
up the PC system. There is nothing you can do about it, except send the PC
system to the supplier for troubleshooting.
2. THE RISK IS HUGE WHILE UPGRADING THE SYSTEM BIOS
In case there is the power break or system hangs while you are upgrading the
system BIOS, you will have a incomplete system BIOS in your mainboard
because only part of the new system BIOS was written into the flash ROM. Of
course, you won't be able to use the PC system any more. Same as what
mentioned above, you have to send the PC system to the supplier for
troubleshooting.
3. WRONG BIOS CAN CAUSE SERIOUS TROUBLE
When you feel like to have the system BIOS got updated, you may have to visit
the web page of the supplier. There are so many different system BIOS included
there in the web page and you may choose the wrong one. Obviously, you will
be in a deep trouble if you are using wrong BIOS to update the system BIOS.
Whenever you are down loading the system BIOS from the web page, be sure to
double check that you are choosing the correct one. Otherwise, you will find the
PC system fail to work when you have the wrong BIOS written into the flash
ROM on the mainboard.
