This bit will be set after the TCO timer times out a second time (Both
TIMEOUT and SECOND_TO_STS bits set).

The bit will reflect the state of the GPI11/SMBALERT# signal, and will depend
on the GP_INV11 bit. It does not matter if the pin is configured as GPI11 or
SMBALERT#.
Unprogrammed flash BIOS bit. This bit will be 1 to indicate that the first BIOS
