 1.6  04-Dec-2003  keihan netbsd.org -> NetBSD.org

All "netbsd.org" is now gone from src/sys/arch.
 1.5  08-Oct-2003  lukem 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!).
 1.4  06-Oct-2003  he Include <string.h> for memset and memcmp prototypes.
 1.3  17-Mar-2002  nonaka branches: 1.3.12;
Already MBR_PTYPE_PREP is defined in sys/disklabel_mbr.h.
 1.2  19-Feb-2001  cgd branches: 1.2.4; 1.2.8;
convert to use getprogname()
 1.1  18-Sep-2000  nonaka branches: 1.1.2; 1.1.4;
Added installboot program.
 1.1.4.3  12-Mar-2001  bouyer Sync with HEAD.
 1.1.4.2  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
 1.1.4.1  18-Sep-2000  bouyer file installboot.c was added on branch thorpej_scsipi on 2000-11-20 20:23:11 +0000
 1.1.2.2  20-Sep-2000  nonaka Pull up (approved by thorpej)

- Added installboot program.
 1.1.2.1  18-Sep-2000  nonaka file installboot.c was added on branch netbsd-1-5 on 2000-09-20 13:58:05 +0000
 1.2.8.1  01-Apr-2002  nathanw Catch up to -current.
(CVS: It's not just a program. It's an adventure!)
 1.2.4.1  23-Jun-2002  jdolecek catch up with -current on kqueue branch
 1.3.12.3  21-Sep-2004  skrll Fix the sync with head I botched.
 1.3.12.2  18-Sep-2004  skrll Sync with HEAD.
 1.3.12.1  03-Aug-2004  skrll Sync with HEAD
 1.7.92.1  13-May-2009  jym Sync with HEAD.

Commit is split, to avoid a "too many arguments" protocol error.
 1.7.86.1  28-Apr-2009  skrll Sync with HEAD.
 1.7.78.1  04-May-2009  yamt sync with head.
