[Qemu-devel] [PATCH v8 2/4] i386: expose floppy drive CMOS type

[Roman Kagan <rkagan@virtuozzo.com>]

Make it possible to query the CMOS type of a floppy drive outside of the
source file where it's defined.

It will allow to properly populate the corresponding ACPI objects and
thus enable Windows on BIOS-less systems to access the floppy drives.
