* stage2/char_io.c [!GRUB_UTIL] (memcpy): New function. It is
	defined as an alias of grub_memmove. This is copied from GRUB 2.

	* stage2/disk_io.c (print_completions): Simplified conditionals
	to make it easier to edit the file with Emacs.
	Added support for (cd).
	(set_device): Likewise.

	* stage2/common.c (init_bios_info): Check if BOOT_DRIVE is a
	CDROM drive. If it is true, set CDROM_DRIVE to BOOT_DRIVE.
	(cdrom_drive): New variable.

	From Leonid Lisovskiy <lly@pisem.net>:
	* stage2/start_eltorito.S: New file.

	* stage2/stage2.c (run_menu): Use GRUB_INVALID_DRIVE instead of
	0xFF.

	* stage2/shared.h (STAGE2_ID_ISO9660_STAGE1_5): New macro.
	[FSYS_ISO9660] (STAGE2_ID): Set to STAGE2_ID_ISO9660_STAGE1_5.
	(struct geometry): Added a new member ``sector_size''.
	(BIOSDISK_FLAG_CDROM): New macro.
	(cdrom_drive): Declared.

	* stage2/fsys_iso9660.c: New file.
	* stage2/iso9660.h: Likewise.

	* stage2/filesys.h (FSYS_ISO9660_NUM): New macro.
	[FSYS_ISO9660] (iso9660_mount): Declared.
	[FSYS_ISO9660] (iso9660_read): Likewise.
	[FSYS_ISO9660] (iso9660_dir): Likewise.
	(NUM_FSYS): Added FSYS_ISO9660_NUM.

	* stage2/disk_io.c (fsys_table) [FSYS_ISO9660]: Added iso9660.
	(current_drive): Use GRUB_INVALID_DRIVE.
	(log2): New function.
	(rawread): Use BUF_GEOM.SECTOR_SIZE instead of SECTOR_SIZE.
	Change the type of BUFADDR from int to char *.
	Use a virtual track to make sure that one track fits in the
	buffer.
	(sane_partition): Allow CURRENT_DRIVE to be CDROM_DRIVE, because
	a bios drive for a CD-ROM is often assigned to greater than
	0x88.
	(set_device): Use GRUB_INVALID_DRIVE instead of 0xFF.
	(setup_part): Likewise.

	* stage2/cmdline.c (init_cmdline): Use GRUB_INVALID_DRIVE.

	* stage2/builtins.c (install_func): Use GRUB_INVALID_DRIVE.
	(setup_func): Added iso9660_stage1_5.

	* stage2/bios.c (biosdisk): Don't fall back to the CHS mode
	if the drive is a CDROM.
	(get_cdinfo): New function.
	(get_diskinfo): Call get_cdinfo if the drive is greater than or
	equal to 0x88 or the drive supports LBA.
	Set the sector size to SECTOR_SIZE if it is not a CD-ROM.

	* stage2/asm.S (biosdisk_int13_extensions): Take a word
	argument AX instead of a byte argument AH.
	(get_diskinfo_int13_extensions): Removed.

	* stage2/Makefile.am (noinst_HEADERS): Added iso9660.h.
	(libgrub_a_SOURCES): Added fsys_iso9660.c.
	(libgrub_a_CFLAGS): Added -DFSYS_ISO9660=1.
	(pkgdata_DATA): Added iso9660_stage1_5 and stage2_eltorito.
	(noinst_PROGRAMS): Added iso9660_stage1_5.exec and
	start_eltorito.exec.

	(iso9660_stage1_5_exec_CCASFLAGS): Likewise.
	(iso9660_stage1_5_exec_LDFLAGS): Likewise.

	* stage1/stage1.h (GRUB_INVALID_DRIVE): New macro.

	* stage1/stage1.S (boot_drive): Use the macro GRUB_INVALID_DRIVE.
	(real_start): Likewise.

	* lib/device.c (get_drive_geometry): Set GEOM->SECTOR_SIZE to
	SECTOR_SIZE by default.

	* configure.ac (--disable-iso9660): New option.
