1.2 AIR BUS -
There is a revolutionary new interface designed on the mainboard - the AIR Bus (
CN25 ). There is the "KEYBIOS" device is designed to connect to the AIR Bus
and it will give you lots of incredible features to your PC system.
Why AIR Bus?
One of the most significant and immediate feature from AIR bus is it will rescue
your system BIOS from virus attack. 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, similar virus will become popular and the protection to the
mainboard will be surely necessary and extremely important.
Everyone can see that the PC system will be failed to boot when the system BIOS
is destroyed. There is no perfect prevention for such virus attack because there is
always the new virus invented. However, AIR Bus can be one of the best solution
to rescue your PC system from virus attack because it is an intelligent interface and
it will restore the system BIOS automatically.
In case that the PC system is infected by virus and the system BIOS is destroyed,
users have to call for help or send the PC system to the dealer for trouble shooting.
However, you do have to wait for such technical support because the AIR Bus will
have the system BIOS get recovered within a single minute. The recovery
procedure is done automatically and you do not have to make any hardware or
software setting. Simply plug in the " KEYBIOS " and click on the power button,
and then leave everything done by the " KEYBIOS ".
Besides, the " KEYBIOS " can be used as a spare copy of the system BIOS. No
matter how serious of damage is made to your system BIOS, whenever there is the
" KEYBIOS " connected to the AIR Bus, the system BIOS will be replaced by
the " KEYBIOS " and that will keep your PC system alive.
More than just a mainboard.
The " KEYBIOS " is a programmable device and many special software tools
can be introduced on it. Since " KEYBIOS " is active before the OS is loaded, so
it will provide lots of amazing feature. For example, the " KEYBIOS " can be
used for security purpose and that will keep the unauthorized person away from
your PC system. The design of the AIR Bus is simple, but the features introduced
to the " KEYBIOS " will come out with many amazing function and you will
discover that what you received is more than just a regular mainboard. Please
contact your dealer for more detail features on the AIR bus.
