If, during
bootup,
the BIOS program detects a problem in the integrity of
the CMOS, it will display a message asking you to either press the
<DEL> key to run Setup or the
<
Fl
> key to resume booting. This prob­ably means that the CMOS values have been corrupted or modified incor­rectly, perhaps by an application program that changes data stored in CMOS.
Press the
<
Fl
>
key to resume the boot or <DEL> to run Setup
with
the ROM default values already loaded in the menus. You can make other changes before saving the values to CMOS.
