The current DriverSampleDxe has the following item for the orderedlist:
option text = STRING_TOKEN(0x006F), value = 2, flags =
RESET_REQUIRED;
option text = STRING_TOKEN(0x006E), value = 1, flags =
RESET_REQUIRED;
option text = STRING_TOKEN(0x0070), value = 3, flags =
RESET_REQUIRED;
The VFR specification lists both RESET_REQUIRED and INTERACTIVE for the
"option" flags field.
But the UEFI specification says:
FlagsSpecifies the flags associated with the current option. See
EFI_IFR_OPTION_x.
#define EFI_IFR_OPTION_DEFAULT 0x10
#define EFI_IFR_OPTION_DEFAULT_MFG 0x20
The VFR specification then goes on to say:
Therefore, the options' flags are treated as question flags and can accept all
values of question flags.
What is not clear is: do these flags enable some extension to the UEFI
specification? (since theses flags are not in the specification) or are these
flags, in effect, promoted so that the question's Flags field bit will be set
IF any option has the field bit set?
