Award BIOS Setup Utility
If in the “CPU Clock Ratio” field, you selected an option other than
the default setting and is unable to boot up the system, there are 2
methods of booting up the system and going back to its default
setting.
Method 1:
Clear the CMOS data by setting JBAT1 to 2-3 On. All fields in the
BIOS Setup will automatically be set to their default settings.
Method 2:
Press the <Inser t> key and power button simultaneously, then
release the power button first. Keep-on pressing the <Insert> key
until the power-on screen appears. This will allow the system to boot
according to the FSB of the processor. Now press the <Del> key
to enter the main menu of the BIOS. Select “Frequency/Voltage
Control” and set the appropriate field to its default setting or an
appropriate frequency ratio.
Note:
• Use a PS/2 or AT (requires a DIN to mini DIN adapter)
keyboard for method 2.
• When using a 66MHz FSB processor with PC-100 SDRAM
DIMM, the system memor y clock is 3/2 of the CPU’s
external bus clock and the PCI clock is 1/2 of the CPU’s
external bus clock.
• When using a 100MHz FSB processor with PC-100
SDRAM DIMM, the system memory clock is the same as
the CPU’s external bus clock and the PCI clock is 1/3 of
the CPU’s external bus clock.
• When using a 133MHz FSB processor with PC-100
SDRAM DIMM, the system memory clock is 3/4 of the
CPU’s external bus clock and the PCI clock is 1/4 of the
CPU’s external bus clock.
