* stage2/bios.c (get_diskinfo): Clear out the structure DRP
	before calling get_diskinfo_int13_extensions, because the Ralf
	Brown's Interrupt List says that Dell machines using PhoenixBIOS
	4.0 Release 6.0 fail, if DRP.FLAGS is not zero. Setting the
	entire structure to zero may be overkill, but it should be safe.

	* stage2/char_io.c [STAGE1_5] (grub_memset): Defined.
