Probably depends on the hardware.  I'm pretty sure that *some* eeproms
are writable.

Remember that the BIOS is stored in one of what may be several eeproms in the
system - graphics cards and other controllers probably have their own eeproms.

You might want to think about why most systems do a restart after updating the BIOS,
and then ask yourself if you really want to write to it while the system is up....

Depends on which eeprom you're talking about.
