Introduction of BIOS
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In
this case, turn the system off than on again. The CPU will automatically use its
standard parameters to boot. You can then enter BIOS Setup again and set up
the CPU clock.
If you can't enter BIOS setup , you must try turning the system on a few
times (3~4 times) and the system will automatically use its standard parameters
to boot.
You can then enter BIOS SETUP again and set up the new
parameters.
When you change your CPU:
The mainboard have been designed in such a way that you can turn the
system on after having inserted the CPU in the socket without having to
configure any jumpers or DIP switches. But if you change your CPU, normally,
you just have to turn off the power supply, change the CPU and then, set up the
CPU parameters through CPU SOFT MENU™. However, if the CPU brand
and type is the same, and if the new CPU is slower than the old one, we offer you
two methods to successfully complete the CPU change operation.
Method 1: Setup up the CPU for the lowest speed for its brand. Turn the
power supply off and change the CPU. Then turn the system on
again, and set up the CPU parameters through CPU SOFT
MENU.
Method 2: Since you have to open the computer case when you change the
CPU, it could be a good idea to use the CCMOS jumper to erase
the parameters of the original CPU and to enter BIOS Setup to
set up CPU parameters again.
Note :
The increase by 2.5% of the CPU speed is not a standard feature
of this product. It is only for use by our development department
ä Enable: CPU external clock is operating within the limits
of the Turbo mode.
