- * 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.
