Introduction of BIOS 3-5

Turbo Frequency:
This item will only be displayed if your CPU external clock supports
Turbo mode.
The Turbo mode allows you to speed up the external clock by
approximately 2.5%. This feature is used to verify the design
flexibility. It is a very important tool for test units to verify CPU
stability. Do not use this feature.
➤ Disable: CPU external clock is operating within the
normal limits.
➤
Enable: CPU external clock is operating within the
limits of the Turbo mode.
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) or press “ INSERT “ key when turn on 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 motherboard 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
™
II 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
