christos 5de69f0012 fix compilation on LP64 machines. 2005-12-28 06:03:15 +00:00
jmmv fbb8b4076f Add an option (-s) to specify which sector to read to parse the partition
table.  Useful if the disk has remapping drivers installed into it (such as
Ontrack Disk Manager).

Added as an option instead of automatic behavior to let the user scan any
of the two partition tables at will.

jmmv b635f565e7 Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

lukem 1c33b4e6a4 Overhaul MBR handling (part 1):
<sys/bootblock.h>:
    *	Added definitions for the Master Boot Record (MBR) used by
	a variety of systems (primarily i386), including the format
	of the BIOS Parameter Block (BPB).
	This information was cribbed from a variety of sources
	including <sys/disklabel_mbr.h> which this is a superset of.

	As part of this, some data structure elements and #defines
	were renamed to be more "namespace friendly" and consistent
	with other bootblocks and MBR documentation.
	Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
    *	Deprecated in favor of <sys/bootblock.h> (the latter is more
	"host tool" friendly).

amd64 & i386:
    *	Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
	be consistent with the naming convention of the msdosfs tools.

    *	Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
	and it's confusing to have two functionally equivalent bootblocks,
	especially given that "ufs" has multiple meanings (it could be
	a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

    *	Rework pbr.S (the first sector of bootxx_*):
	    +	Ensure that BPB (bytes 11..89) and the partition table
		(bytes 446..509) do not contain code.
	    +	Add support for booting from FAT partitions if BOOT_FROM_FAT
		is defined.  (Only set for bootxx_msdos).
	    +	Remove "dummy" partition 3; if people want to installboot(8)
		these to the start of the disk they can use fdisk(8) to
		create a real MBR partition table...
	    +	Compile with TERSE_ERROR so it fits because of the above.
		Whilst this is less user friendly, I feel it's important
		to have a valid partition table and BPB in the MBR/PBR.

    *	Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
	with other platforms.

    *	Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
    	we can boot off FAT partitions.

    *	Crank version of /usr/mdec/boot to 3.1, and fix some of the other
	entries in the version file.

installboot(8) (i386):
    *	Read the existing MBR of the filesystem and retain the BIOS
    	Parameter Block (BPB) in bytes 11..89 and the MBR partition
	table in bytes 446..509.  (Previously installboot(8) would
	trash those two sections of the MBR.)

mbrlabel(8):
    *	Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
	to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

lukem fbace08ced change behaviour of flags slightly:
-w	write in-core label if changed
-r	update on-disk as well as in-core label (with -w)
-f	force update (-w), even if there's been no change

-r behaviour suggested by matt green. what used to be `-f' is now `-wrf'

lukem a9dd32dbb7 more rewording
- mbrlabel updates the disklabel; it doesn't generate it
- it doesn't just affect the incore label, so remove the `incore' qualifier
2000-12-24 14:01:12 +00:00
lukem 747375caa2 i got sick of the brain damage that mbrlabel used to do, and had
gotten bitten by mbrlabel trashing my incore disklabel to a point where
the machine wasn't usable, so I reworked it:

* only update the incore (and on-disk) label if `-f' is given. by default,
  the proposed disklabel will be printed but no changes will occur
* add -q, to make the default operation a bit more quiet.
* leave existing `used' in-core partition slots alone, and only add entries
  to the incore label if:
	- there's not an existing partition of the same size and offset
	  (even of a different type)
	- there's a free partition slot (`unused', with size == 0)
* use DIOCWDINFO instead of DIOCSDINFO, to update the incore as well as
  the on-disk label
* use showpartitions() from ../disklabel/printlabel.c

this should make mbrlabel a *lot* more useful.
