boot-up.  If it detects that the CPU fan is not rotating, the system will show an
error message on the screen and halt the boot-up process.
CPU/System Temperature, CPU/System Fan Speed, Vcore, +5.0V, +12.

MS-6593 ATX Mainboard
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec-
trum function reduces the EMI generated by modulating the pulses. Remem-
ber to disable Spread Spectrum if you are overclocking.
CPU FSB Clock
This item allows you to select the CPU Front Side Bus frequency (in MHz)
and overclock the processor by adjusting the FSB clock to a higher frequency.
CPU Ratio/Vcore (V)
The settings are used to adjust the CPU clock multiplier (ratio) and CPU core
voltage (Vcore) for overclocking purposes. Changing CPU Ratio/Vcore could
result in the instability of the system; therefore, it is NOT recommended to
change the default setting for long-term usage.
DDR Voltage (V)
Adjusting the DDR voltage can increase the DDR speed.  Any changes made
to this setting may cause a stability issue, so changing the DDR voltage for
long-term purpose is NOT recommended.
AGP Voltage (V)
Adjusting the AGP voltage increases the performance of your AGP display
card when overclocking, but the stability may be affected.

BIOS Setup
Set Supervisor/User Password
Type the password, up to six characters in length, and press .
 The password typed now will replace any previously set password from
CMOS memory. You may also press  to abort the setting and not enter
a password.
To clear a set password, just press  when you are prompted to
enter the password. Once the password is disabled, the system will boot and
you can enter Setup without entering any password.
When a password has been set, you will be prompted to enter  it every
time you try to enter Setup. This prevents unauthorized access to your system.
Please especially note that Supervisor can enter and change the set-
tings of the setup menu while User can only enter but do not have the right
to change the settings of the setup menu.
Load High Performance/BIOS Setup Defaults
The High Performance Defaults are the values set by the mainboard
manufacturer for the best system performance but probably will cause a sta-
bility issue.
The BIOS Setup Defaults are the default values also set by the mainboard
manufacturer for stable performance of the mainboard.
