* include/grub/i386/linuxbios/memory.h
	(GRUB_MEMORY_MACHINE_LINUXBIOS_TABLE_ADDR): Remove macro.
	* kern/i386/linuxbios/table.c (grub_linuxbios_table_iterate): Do not
	receive `table_header' as argument.  Instead, probe for it in the
	known memory ranges where it can be present.
	(grub_available_iterate): Do not pass a fixed `table_header' address
	to grub_linuxbios_table_iterate().
