<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!).

# $NetBSD: README.files,v 1.2 2002/09/23 08:02:34 lukem Exp $ What's in this directory: CHANGES Changes between the XXX.XXX-1 and XXX.XXX releases. CHANGES.prev Changes in previous NetBSD releases. LAST_MINUTE Last minute changes and notes about the release. README.files This file. patches/ Post-release binary code patches. shared/ Binary sets shared between multiple ports. source/ Source code. source/sets/ Source distribution sets; see below. source/patches/ Post-release source code patches. In addition to the files and directories listed above, there is one directory per architecture, for each of the architectures for which NetBSD XXX.XXX has a binary distribution. The contents of each architecture's directory are described in an "INSTALL" file found in that directory. The most recent list of mirror sites for NetBSD is viewable at the URL: http://www.NetBSD.org/Sites/net.html If you are receiving this distribution on a CD set, some files and subdirectories may be on a separate disc; read all README files for more information. See http://www.NetBSD.org/Misc/crypto-export.html for the formal status of the exportability out of the United States of some pieces of the distribution tree containing cryptographic software. If you export these bits and the above document says you should not do so, it's your fault, not ours.
