want to keep or delete the dist files.
Stop the "type enter to continue" if the rmdir fails - may not be empty.
Report an error if the chroot() (for RUN_CHROOT) fails.
fflush log and script files before writing to them from a child.
Move info about cylinders to the 'ask for units' menu.
(translations need checking, done by cutting sentences)
Stop i386 always asking for units.
Use BIOS cylinders for MBR and disk cylinders for the disklabel.
(code intended to do this, but got it wrong...)
Mark some menus as 'sub menu' or MC_SUBMENU so that the screen underneath
is saved.
Add GENERIC.MPACPI to i386 menu.
and bcylsize (bios cylinder size) can be calculated in the one place
it is needed.
The ask_sizemult() call will go once I decide what to to with the
(slightly useful) explanatory text about cylinder alignment.
written into the correct place - even if the user decides not to update
the mbr code and has the old (pre layout change) code installed.
Tell the user that the mbr code needs updating if the new install uses
'all the disk' and teh old version had the bootselect code (otherwise you
get an empty menu).
Probably fixes PR install/25146
that has holes.
This needs the 'bios sectors per track' before it has been setup - so we
default it to the 'hardware' value. Since both numbers are 63, and this only
affects the size of the headers on extended partitions it should be safe.
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.
Don't write out dummy extended partitions for unused ares in the extended
partition.
Add some more comments - I write this and I couldn't remember how it worked.
down to a cylinder boundary before adding in the requested size.
Stops the partition being one cylinder larger than requested when the
partition doesn't start at the beginning of a cylinder (eg for partitions
starting in sector 63).
Fixes part of PR install/23548
- rework run_prog() so that the program name (etc) is usually displayed if
the program generates any output, or terminates with an error.
Allow arguments to included in single quotes.
Try to collect console output so it doesn't interfere with curses.
- Add a '*' to the cylinder count if non-integral number of cylinders
(on disklabel editor)
- Only show partition type for unused partitions.
- Show size including unused space on '+' partition, remove a..z since
the don't relate to partition IDs (netbsd partition sizes)
- Fix deleting of 'user' partitions - killed size of next ptn.
- Don't default a swap partition is the disk already has one.
- Fix deleting of extended MBR partitions - changed size of ptn 2.
- Show error message if user tries something illegal in mbr editor.
- Default to old diskname (actually disk type - dunno why!)
- Use MI enable_rc_conf() to set RC_CONFIGURED=YES, use a single sed
command instead of a raft of code playing with files etc.
- Float some menus to just below header text, saves counting and lets
language variants have different height headers (use y=-1)
- Track whether anything is mounted on /mnt2 better.
- Put more texts into message file.
- Change english prose texts to be more correct.
- Stop french and polish versions core dumping if ptn start/size changed.
- Fix processing logic for saving /etc (action is still borked)
- Do tail-end setup if any sets (eg X) can't be found (but not if you give
in (yet)).
<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!).
Add menu for all disklabel partition types.
Default 'partition type' and 'sizechoice' menus to current value.
Change 'standard/use existing' to 'set sizes/use existing'.
When asking for bios geometry, ask for sectors per track and heads
then calculate cylinders from volume size.
Write MBR_MAGIC into correct place when writing extened partitions.
Make disk_desc[], disk and numdisks local to get_disks (instead of globals).
Fix a little fallout from the above.
A bit of mbr.c was missing #ifdef BOOTSEL...
This should stop the i386 code splatting all over the start of the disk
during upgrade.
Upgrade will still use partition 'a' (unless you loop through the install
far enough first!)
Remove pointless 'len' parameter from read_mbr and write_mbr.
Make read_mbr initialise mbr if it can't be read (delete MD code).
Make i386 always ask at least once about the bootcode.
Move LIB_MOVE and LIB_COUNT from md.h to aout2elf.c
Make same function return useful defaults if it can't find an answer.
Make all ports default to the useful defaults if bios geometry is unknown.
Move some messages to mbr set from mi set.
Fix i386 code that selects which bios disk, simplify interface to menus.
Remove now unnecessary global data from many ports.
This does change the default size of /, but I'm going to rewrite
make_bsd_partitions next to make it less user-hostile.
(I'm not sure adding in 2 * ram is actually useful! Especially size it left
/usr with a -ve size on all my test installs with 256MB ram and 1GB disk)
Make bootsel code delete menu names if the partition is unused.
Use raw device for cdrom access (I've a kernel that doesn't report an invalid
label so /dev/cd0a dosn't work).
left consistently.
Make the i386 install let you partition a disk beyond the CHS limit if the
system bios doesn't support LBA reads (the checks aren't ideal yet).
Make the bsddislabel.c code usable onan i386 system - but don't use it yet.
(I hope the edits for the ports I can't build are right!)
i386/amd64 pick up a minor change to the md_read_bootcode which
might preseve the bootselect config.
that can be specified with CHS, truncate it to the maximum values that
the BIOS provided, not 1023*255*63. Some BIOSs get awfully cranky when
you do that.
