Chapter 3
AT7/AT7E
3-2
In the BIOS Setup main menu of Figure 3-1, you can see several options. We will explain these options
step by step in the following pages of this chapter, but let us first see a short description of the function
keys you may use here:
! Press Esc to quit the BIOS Setup.
! Press ↑↓←→ (up, down, left, right) to choose, in the main menu, the option you want to confirm
or to modify.
! Press F10 when you have completed the setup of BIOS parameters to save these parameters and to
exit the BIOS Setup menu.
! Press Page Up/Page Down or +/- keys when you want to modify the BIOS parameters for the active
option.
Note
Parts of the screenshot may not same as you see on your screen, because the BIOS version may
change periodically. However, most of the functions covered in this manual will work. We suggest
that you go to our WEB site often to see if there are new manual releases. Then you can check the
newly updated BIOS items.
Computer Knowledge: CMOS Data
Maybe you have heard somebody saying that his or her CMOS DATA was lost. What is the CMOS?
Is it important? The CMOS is the memory used to store the BIOS parameters that you have
configured. This memory is passive. You can read its data, and you can also store data in it. But this
memory has to be powered by a battery, in order to avoid any loss of its data when the computer is
turned off. Since you may have to change the CMOS battery when it is out of power and if doing so,
you will loose all CMOS data, therefore, we recommend that you write down all the parameters of
your hardware, or to put a label with these parameters on your hard disk.
