Patch #7alk ... 4 Dec 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) mbadblocks program to mark bad blocks
|
|
2) uses fat_type field of boot block to find out the number
|
|
of fat bits.
|
|
3) is able to format hard disk partitions (untested)
|
|
4) sets _all_ standard fields in boot sector, even without 2m mode.
|
|
5) adds boot code to the boot sector (which transfers booting to
|
|
the hard drive. In most cases, that's what the user wants.)
|
|

Patch #7alk ... 4 Nov 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) Use even disk buffer size whenever possible to workaround a
|
|
bug in Linux blockdev code [???]
|
|
2) Clearer error message on failed sanity check
|
|
3) Removal of BOGUS Notes file
|

Patch #7alk quinter, 2 Nov 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) O_EXCL flag when opening the device to ensure it is not mounted
|
|
2) Sanity checks to avoid accessing non msdos disks
|
|
Both features were suggested by Karl Eichwalder (ke@pertron.central.de)
|

Patch #7alk quater, 1 Oct 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) disk serial number support.
|
|
2) mcheck works for every drive.
|
|
|
|
-----------------------------------------------------------------------------
|
|
Patch #7alk ter, 10 Sep 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) mformat works again.
|
|
2) mmount allows the user to pass arbitrary arguments to mount.
|
|
Floppy disks are no longer mounted by default on /mount/A /mount/B
|
|
etc.
|
|

Patch #7alk bis, 18 jul 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) Support for variable sector sizes.
|
|
2) Support for "2m" formats.
|
|
3) Support for formatting 16-bit fat disks.
|
|
4) Support for formatting ED disks (Their capacity is too big to
|
|
use a 12 bit FAT and 1 sector clusters. Either use bigger
|
|
clusters or a 16 bit FAT)
|
|
5) Mcopying from one DOS drive to another works now. (It used to
|
|
call mktemp on a non-writable string)
|
|
|
|
-----------------------------------------------------------------------------
|
|
Patch #7alk, 16 feb 94
|
|
|
|
This patch adds the following features:
|
|
|
|
1) Mtools can now set the disk geometry on Linux. (Useful for
|
|
reading 1.72 Mb disks. This was already possible on unixpc and
|
|
SPARC )
|
|
2) New mmount command. Reads the boot sector, sets the geometry
|
|
and finally mounts the disk. Only available for Linux.
|
|
3) Mwrite can now write stdout to a DOS file: mwrite - a:test
|
|
4) Mread now also acts as mtype: mread a:test -
|
|
5) Mtools now tries 3 sources to get its drive geometry.
|
|
configuration: first ~/.mtoolsrc, then /etc/mtools, and finally
|
|
compiled-in. ( The two first are conditional on LOADDEVS being
|
|
defined ). LOADDEVS is now compatibles with the various geometry
|
|
setting routines (init_linux, init_sparc and init_unixpc).
|
|
6) Bug fixes for -t mode of mwrite and mread. ( For certain file sizes
|
|
the trailing DOS end-of-file character wasn't correctly written.)
|
|
7) Bug fixes for "drive probing code." (Now failure to lock onto a disk
|
|
causes always trial of the next configuration. Before, mtools used
|
|
to abort on certain cases). Similar fixes in mformat.
|
|
8) Optimization/bug fix of cluster/fat repartition in mformat.c
|
|
9) Made fat checking code optional. (1.72mb disks mformatted with old
|
|
mtools were almost always rejected) To bypass fat-checking set the
|
|
environment variable MTOOLS_FAT_COMPATIBILITY
|
|
10) Mtools now opens /dev/tty to ask for confirmation messages. This
|
|
way, it doesn't interfere with mreading/mwriting from/to stdin/stdout.
|
|
|
|
|
|
CAUTION: I only tested this with Sparc and Linux. Although I left #ifdefs
|
|
for other OS's in devices.c, that doesn't mean that it works on these OS's.
|

Patch #7+, 19 sep 93
|
|
|
|
This patch merges in the mods against 2.05 under Linux. Two are the main
|
|
changes: that all commands are linked as a single executable, which can
|
|
be linked as different name, and that the device specs are no longer
|
|
hardcompiled but are read dynamically from /etc/mtools (the latter change
|
|
is conditional on LOADDEVS being defined).
|
|
|
|
-----------------------------------------------------------------------------
|
|
Patch #7, 6 Sep 92
|
|
|
|
This patch will change the method of determining if the FAT encoding
|
|
scheme in the devices.c file is correct. The method introduced by patch
|
|
#6 was naive and easily fooled.
|
|
|
|
A pre-processor variable called CHK_FAT has been added to the fat_read.c
|
|
file just in case this new method isn't appropriate for all disks.
|
|
|
|
-----------------------------------------------------------------------------
|
|
Patch #6, 21 Aug 92
|
|
|
|
This patch will add the following features:
|
|
|
|
1) Mtools commands now use advisory locks to preclude two
|
|
processes from writing to the same DOS filesystem. You must
|
|
edit the Makefile to choose one of the 3 lock methods:
|
|
-DLOCKF, -DFLOCK, or -DFCNTL.
|
|
See the Configure file for more details.
|
|
|
|
2) An error detection routine has been added to determine if the
|
|
FAT encoding scheme in the devices.c file is correct.
|
|
|
|
3) Mtools commands now return exit codes with the following
|
|
meaning:
|
|
0 = success
|
|
1 = utter failure
|
|
2 = partial success/failure. (at least one successful
|
|
operation, but at least one failure)
|
|
|
|
It also corrects a bug when Mtools is used on machines that have 16 bit
|
|
integers. However, machines with 16 bit integers are limited to FAT
|
|
tables that are less than 64k in length.
|
|
-------------------------------------------------------------------------------
|
|
Patch #5, 25 Aug 91
|
|
|
|
This patch will add a few new features:
|
|
|
|
1) Mtools will now work properly on MSDOS partitions that are
|
|
greater than 32M.
|
|
|
|
2) If the "current working directory" information (contained in
|
|
the $HOME/.mcwd file) is more than 6 hours old, Mtools will
|
|
issue a warning and ignore the old information.
|
|
|
|
3) The mcopy command will now copy files between 2 MS-DOS file
|
|
systems (such as mcopy "a:*" b:).
|
|
|
|
-------------------------------------------------------------------------------
|
|
Patch #4, 11 Apr 91
|
|
|
|
This patch will fix a bug in the mmd command where directories
|
|
inherited the file name extension of the parent directory. It
|
|
also adds a feature that will allow the copying of zero length
|
|
files.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Patch #3, 28 Nov 90
|
|
|
|
This patch will fix a bug where Mtools sometimes bypasses the
|
|
disk "cache" and reads/writes to the disk directly.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Patch #2, 21 Nov 90
|
|
|
|
This patch will fix a bug in the folding of MS-DOS filenames to
|
|
lower case, and will fix a bug that could prevent the detection
|
|
of a full disk.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Patch #1, 12 Oct 90
|
|
|
|
This patch will fix a few problems on Berkeley flavors of Unix,
|
|
and will fix the floating point exception bug when Mtools is
|
|
used with diskettes that have been formatted under very old DOS
|
|
(or formatted by some other non-DOS system).
|
|
|
|
-------------------------------------------------------------------------------
|
|
New in the v2.0 release....
|
|
|
|
1) Support for multiple devices. Mtools now supports:
|
|
multiple floppy disks (A:, B:, etc)
|
|
DOS partitions on a hard disk
|
|
DOS "images" such as those VP/ix uses.
|
|
|
|
2) Wildcards are supported anywhere in a pathname (not just
|
|
in the "filename" part as before)
|
|
|
|
3) Reads and writes to slow devices are now "cylinder buffered"
|
|
when appropriate.
|
|
|
|
4) Versions of CD, FORMAT, LABEL, and ATTRIB have been added.
|
|
|
|
5) A Mtools.1 manual page has been added for an overview of Mtools.
|
|
|
|
6) The mkmanifest command has been added. Although not an 'mtool'
|
|
command, it makes life easier when fixing up Unix filenames that
|
|
get clobbered by MS-DOS file name restrictions.
|
|
|
|
7) The mkdfs program of the "fast-mtools" release for the Sun
|
|
SparcStation can be replaced with mformat.
|
|
|
|
8) The Configure file has been included to help those who must add
|
|
devices to the devices.c file.
|
|
|
|
Many thanks to Viktor Dukhovni (viktor@math.princeton.edu) for
|
|
many of the ideas in the new release.
