+ * 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.
