The following statement appears in DriverSampleDxe for a checkbox:
checkbox varid = MyIfrNVData.ChooseToActivateNuclearWeaponry,
prompt = STRING_TOKEN(0x0029),
help = STRING_TOKEN(0x002A),
flags = CHECKBOX_DEFAULT | CHECKBOX_DEFAULT_MFG,
key = 0,
default = 1,
endcheckbox;
Since a checkbox has a type of Boolean, I would have expected the value after
default to be a Boolean also. vfrConstantValueField is the terminal used to
process these values and this supports "TRUE" and "FALSE" There is no explicit
statement in the VFR spec which says that this will be converted to a type
Boolean. I suggest that these be changed in the sample to use the correct
Boolean values and that the VfrCompiler generate a warning in this case
(something like "forced conversion of integer to Boolean"
I would suggest the same for handling of items such as suppressif 1, or at
least clarify that the compiler will automatically promote integers to Booleans
(because the UEFI spec is pretty clear that this is not a Boolean)
