I do wonder about that. How many BIOS settings are ignored post-boot?
And how many things are left at default by users who never customise
their system?
Some old 7x24 systems continue to work fine running linux and getting time from
the network long after the battery has failed. I assume there are differences in the
way a BIOS deals with a bad battery. A well engineered system should detect
a battery problem and use defaults. I have seen warning messages about a bad
CMOS checksum.
