uwe 3eac78fb64 s/Nm/Nx/, as it's NetBSD that has ports, not fdisk. 2004-07-13 19:24:03 +00:00

sort list of ports where fdisk is available.

darcy e3937fb4c5 Add note top man page explaining that fdisk is not used on all platforms
and list the ones that is is.

Partial fix to PR#25943

lukem a5a429b354 Only examine mbr_bootsel* #ifdef BOOTSEL.
Noted on current-users@ by Markus Hennecke.

lukem 455da8e60b Move mbr_bootsel from offset 404 to offset 400 in struct mbr_sector to
leave 4 bytes for the Windows NT Drive Serial Number (DSN) at 440-443
(as mbr_sector.mbr_dsn).

Ensure that all the MBR & PBR code reserves space for mbr_sector.mbr_dsn.

Leave the bootsel magic number at 444-445 as mbr_sector.mbr_bootsel_magic
(instead of mbr_sector.mbr_bootsel.mbrbs_magic), but use 0xb5e1 (MBR_BS_MAGIC)
instead of 0xaa55 (MBR_MAGIC) to indicate that this change has occurred.

Rework MBR_BS_NEWMBR to mean "mbr_bootsel has moved to 400".

Modify fdisk(8) to automatically relocate the mbr_bootsel from 404 to 400
if mbr_bootsel_magic is the old value (0xaa55), and unset MBR_BS_NEWMBR
to flag that new mbr_bootsel code must be used if updating the MBR.


These changes fixes a problem where Windows 2000 or Windows XP would corrupt
the last 3 bytes + NUL of MBR partition 3's bootsel name if the bootsel name
was 5 characters long, replacing bytes 6-9 with the DSN.
Also, by explicitly reserving the space for the DSN we prevent problems in the
future if non bootsel MBR or PBR code had other information at bytes 440-443.

dyoung 6c02382b7e Add flag -F, options -t disktab and -T disktype to fdisk. Flag -F
indicates that the target of the fdisk operation is a file, not a
disk. With -t and -T, the user tells fdisk the geometry for the
file If the default geometry that fdisk will "fake up" for a file
are not satisfactory, the user may tell the geometry to fdisk using
-t disktab -T disktype.

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!).

386BSD or old NetBSD, and other possibly-familiar (131 for Linux native,
015 for Ext. Partition - LBA) values in with their correct numbers.
