04 Check the CMOS diagnostic byte to
determine whether battery power is
proper and whether the CMOS
checksum is proper. Verify the CMOS
checksum by reading the storage area. If
the CMOS checksum is wrong, update
CMOS with power-on default values and
clear passwords. Initialize data variables
that are based on CMOS setup
questions.
