* structures and definitions for the int 13h, ax={41,48}h
* BIOS Enhanced Disk Drive Services
* This is based on the T13 group document D1572 Revision 0 (August 14 2002)
* available at http://www.t13.org/docs2002/d1572r0.pdf. It is
* very similar to D1484 Revision 3 http://www.t13.org/docs2002/d1484r3.pdf
*
* In a nutshell, arch/{i386,x86_64}/boot/setup.S populates a scratch
* table in the boot_params that contains a list of BIOS-enumerated
* boot devices.
* In arch/{i386,x86_64}/kernel/setup.c, this information is
* transferred into the edd structure, and in drivers/firmware/edd.c, that
* information is used to identify BIOS boot disk. The code in setup.S
* is very sensitive to the size of these structures.
