* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).
first three bytes to determine how much of the BPB to preserve.
Supported values:
eb 3c 90 FAT16 BPB
eb 58 90 FAT32 BPB
(anything else) don't preserve any BPB
This is because the BPB is generally only the FAT16 one except in the
bootxx_msdos case, where it's the larger FAT32 one.
<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!).
arguments, including a clarification that `secondary' is relative to the root
of the filesystem, not a path name to that file if `filesystem' is mounted.
Resolves PR 20977 from Jim Bernard.
all the options have been processed that they are supported my the
specific system.
Add i386 MD options (console, password, speed and timeout)
(Approved by christos and lukem)
o Correct the order of arguments to ffs_read_disk_block; the second one
is blocknumber to read, not the size to be read. This would affect the
UFS2 code, and is thus not much excercised at the moment.
o The offsets in SBLOCKSEARCH are in bytes, but ffs_read_disk_block wants
its location in terms of DEV_BSIZE blocks. Fix this bug in ffs_match().
The latter together with the recent magic number fix to <ufs/ffs/fs.h>
fixes a cross build problem seen when doing a i386->sparc build.
64 bit block pointers, extended attribute storage, and a few
other things.
This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

bbinfo.c module; news* boot blocks occupy all of the first 16 sectors,
with a jump instruction to skip the label at bytes 64..511.
Replace news_clearboot() and news_setboot() callbacks with common
news_copydisklable() callback, and set bbinfo_params->offset to
NEWS_BOOT_BLOCK_OFFSET (which is now 0), and ->headeroffset to 0.
(Thanks to Izumi for picking this up; the perils of working on code at 2am)
- bbinfo_params:
- replace "int littleendian" with "bbinfo_endian endian"
- add comments
- shared_bbinfo_clearboot():
- add callback method to shared_bbinfo_clearboot()
- don't clear from 0..headeroffset; use a callback to do that
- add news68k and newsmips support.
From Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>, with a rework by me to
take advantage of the new shared_bbinfo_clearboot() callback.
(XXX: untested yet)
column gets a trailing "," if there's more entries to come.
- if getmachines() or getfstypes() is called with 3 NULL params, just
print the list of supported items.
- in usage(), call getmachines() and getfstypes() with 3 NULL params.
(i got sick of typing "installboot -m asdf" to get a list of
supported machines during testing :)
