Yes, ACPI 6.2, section 9.20.7.2, defines that:
Upon receiving the notification, the OSPM may decide to issue
a Start ARS with Flags Bit [1] set to prepare for the retrieval
of existing records and issue the Query ARS Status function to
retrieve the records.
So, I believe it is safe to assume that BIOS supporting 0x81 also
supports flags Big [1]. Sorry, this is what I should have said in my
previous email...
