CMOS Setup
Here you can setup the basic BIOS features such as date, time, type
of floppy etc. Use the arrow keys to move around and press enter to
select the required option. You can specify what IDE devices you have
such as Hard drive, CD-ROM, ZIP drive etc. The easiest way to setup the
IDE devices is by leaving it set to auto. This allows the BIOS to detect
the devices automatically so you don’t have to do it manually. At the
bottom, it also displays the total memory in your system. See figure 1.
As you can see from figure 3, there are numerous advance settings
which you can select if required. For most cases leaving the default
setting should be adequate. As you can see the first boot device is set
to floppy. This ensures that the floppy disk is read first when the
system boots, and therefore can boot from windows boot disk. The second
boot device is the Hard disk and third is set to LS120. If you want to
boot from a bootable CD then you can set the third boot device to
CD/DVD-ROM. See Figure 2.
Here you can setup the contents of the chipset buffers. It is closely
related to the hardware and is therefore recommended that you leave the
default setting unless you know what you are doing. Having an incorrect
setting can make your system unstable. If you know that your SDRAM can
handle CAS 2, then making changes can speed up the memory timing. If you
have 128MB SDRAM then the maximum amount of memory the AGP card can use
is 128MB. See Figure 3
This menu allows you to change the various I/O devices such as IDE
controllers, serial ports, parallel port, keyboard etc. You can make
changes as necessary. See figure 4.
The power management allows you to setup various power saving features, when the PC is in standby or suspend mode. See figure 5.
This menu allows you to configure your PCI slots. You can assign
IRQ’s for various PCI slots. It is recommended that you leave the
default settings as it can get a bit complicated messing around with
IRQ’s. See figure 6.
This menu displays the current CPU temperature, the fan speeds,
voltages etc. You can set the warning temperature which will trigger an
alarm if the CPU exceeds the specified temperature. See figure 7.
If you made changes to the BIOS and your system becomes
unstable as a result, you can change it back to default. However if you
made many changes and don’t know which one is causing the problem, your
best bet is to choose the option “Load Fail Safe Mode Defaults” from the
BIOS menu. This uses a minimal performance setting, but the system
would run in a stable way. From the dialog box Choose “Y” followed by
enter to load Fail-Safe Defaults.
Like the Fail-Safe mode above, this option loads the
BIOS default settings, but runs the system at optimal performance. From
the dialog box Choose “Y” followed by enter to load Optimized Defaults.
To password protect your BIOS you can specify a
password. Make sure you don’t forget the password or you can not access
the BIOS. The only way you can access the BIOS is by resetting it using
the reset jumper on the motherboard.
To save any changes you made to the BIOS you must choose this option. From the dialog box choose “Y”.
If you don’t want to save changes made to the BIOS, choose “N” from the dialog box.
