 * 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  It is
 * very similar to D1484 Revision 3
 * 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.
