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

with

the
ROM default values already loaded in the menus. You can make other
changes before saving the values to CMOS.
