Changing settings
To choose an item, first move the cursor onto a desired field with the arrow keys. Next, select a
value in the field with + (
PageUp ) or – ( PageDown ). Finally, select the
Save & Exit Setup
command in the main menu, which saves the currently displayed values of all the menus.
BIOS Setup Main Menu
The BIOS setup main menu contains the following items:
Table A-1 BIOS setup main menu
Item Contents
Standard CMOS Features Sets the date, time, IDE device items, floppy drive items, video adapter items and
startup system stop conditions. As the time and date change, these changes are
reflected on the CMOS. When executing the Load Fail-Safe Defaults or the Load
Optimized Defaults a prescribed value is preset for items other than the date or
time. When the “CMOS checksum error - Defaults Loaded” message is displayed,
execute the “Load Optimized Defaults” and at least confirm or change the date
and time.
Advanced BIOS Features These features set fundamental BIOS items, such as the cache, POST conditions,
bootup sequence and memory shadowing.
Advanced Chipset Features These features set items related to memory timing, BIOS code cashing, video
memory timing and the chipset control timing. Since these settings are executed
via the Load Optimized Defaults, they are the optimum settings for the system and
generally
do not need to be changed . Be aware that because these settings
pertain to the control timing, the apparatus may fail to start up if an incompatible
setting is executed.
Integrated Peripherals Sets items for controlling the input and output for the IDE controller, the USB
controller, the parallel port, and the serial port.
Power Management Setup Sets items related to BIOS based power regulation of the power management
timer, wake-up event and timer reset event.
PnP/PCI Configurations Sets items related to system resource allocation of IRQ numbers and DMA channel
numbers.
Frequency/Voltage Control This menu is used to set items related to clock control; however, it only displays
items and no selection can be made. The optimum value is set for each item by
the BIOS at startup.
Load Fail-Safe Defaults The load fail/Safe defaults are executed when the minimum preset prescribed
values required for the startup are set for each item. This function is only provided
for troubleshooting and is normally not used.
Load Optimized Defaults The load optimized defaults are executed when preset prescribed values are set
for each item so that the system operates under optimum conditions. It is also
executed when the “CMOS checksum error - Defaults Loaded” message is
displayed and each item is restored to its prescribed value.
Set Supervisor Password This function sets the system protection password. The password can be set for up
to 8 characters (case-sensitive). The input demand timing for the password setting
differs according to the setting for Advanced BIOS Features: Security Option.
Set User Password This function sets the system protection password. The password can be set for up
to 8 characters (case-sensitive). The input demand timing for the password setting
differs according to the setting for Advanced BIOS Features: Security Option.
Save & Exit Setup This is executed at restart after saving CMOS content changes.
Exit Without Saving This is executed at restart without saving CMOS changes (cleared).
