[Xen-devel] [PATCH] Fix EDD pointer in int 13h, fn 48h BIOS call return buffer

["Bruce Rogers" <brogers@xxxxxxxxxx>]

I ran into this when I was reviewing what was outstanding to get NetWare to run 
fully virtualized.

The BIOS emulator code has the segment and offset backward in the returned 
buffer for the int 13h, fn 48h BIOS call.

BTW: This is fixed in current Bochs emulator upstream code.
