This main menu option loads the system default values stored in
the BIOS ROM at the factory.
This main menu option loads the settings stored in the CMOS
memory when you turned on your system. If your system behaves
erratically, you can use this feature to check for incorrect settings.
This option lets you perform low-level hard disk drive preparation
before you use the DOS FDISK or FORMAT utilities. All of its
functions are destructive to existing data on the disk drive.
Most IDE hard drives come preformatted from the factory, so you
will probably only need these utilities if your hard disk develops
bad sectors or ages and needs to have the formatting information
refreshed.
After you have made your configuration changes, select Write to
CMOS and Exit. If you decide you want to abandon the changes
you have made, select Do not Write to CMOS and Exit.
The BIOS will then perform a memory test, and attempt to boot
your system.
Be sure that your DOS system files are located on either drive A:
or on your hard disk drive. If they are not, the BIOS will not be
able to boot your system.
