Introduction of BIOS 3-5
Default setting is “ 2/3”. In this state, AGP bus speed will be CPU
bus speed divided by 3 and times 2. If you choose the setting to
“ 1/1 ”, AGP bus speed will equal to CPU bus speed.
<Note 5> L2 Cache Latency:
Sixteen setting are available, Default, and 1 to 15. This item can let
you adjust the processor L2 cache speed, the larger the value, the
faster the L2 cache will run. You have to be aware that if you set the
L2 cache speed too fast, it will cause the L2 cache to fail. If the L2
cache fails it will cease to run until you reset the value, but the
processor and L1 cache will still function, just not as well. To make
sure your L2 cache functions properly please choose an appropriate
setting. The default setting is Default.
<Note 6> Speed Error Hold:
Default setting is “Disable”. If you choose the setting to “Enable”,
when CPU speed setting is wrong, then system will hold.
Normally, we do not recommend that you use the “User Define” option to setup
CPU speed and multiplier factor. This option is for setup of future CPUs whose
specifications are still unknown. The specifications of all present CPUs are
included in the default settings. Unless you are very familiar with all CPU
parameters, it is very easy to make mistakes when you define by yourself the
external clock and the multiplier factor.
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.
