Bummer! Yes. Generally, it's on a per controller ROM revision basis, and is not specific to internal machine BIOS. It gets the general name of "BIOS" because the POST routines on the card point the INT 13 interface to their own ROMs, replacing/chaining the default BIOS. And there's no way to ask... there's a way to figure it out that mostly works, but which can run into LCF problems.
