More User-Hostile software from Zen Works, the source of Odd Tools
for Odd Jobs.
WARNING!!!
~~~~~~~~~~
USE OF THIS PROGRAM IS ENTIRELY AT YOUR OWN RISK!!
SINCE NEITHER ZEN WORKS NOR THE PROGRAMMER HAS ANY
CONTROL OVER YOUR ACTIONS OR LEVEL OF INCOMPETENCE,
WE REFUSE TO ACCEPT RESPONSIBILITY FOR ANY AND ALL
DAMAGE THAT MAY RESULT FROM YOUR USE OR MISUSE OF
THIS SOFTWARE.
Brect is short for Boot Rectify (hard to find good names that some
one else hasn't used) and is intended for use as a brute force
method of removing Stoned.16, or similar boot sector viruses, from
floppy diskettes when the usual assortment of anti-virus software has
failed to do the job.
Software around here always starts out as a quick-and-dirty utility
designed to deal with a specific situation, then grows into something
much more complex.
Brect was originally written (in Assembler, of course) to clean a
batch of floppy diskettes infected with the Stoned.16 virus when it
was apparent that nothing else could clean them.
Some of the diskettes could be read, so the files could have been
copied to clean diskettes, but that entailed an excessive amount of
work, and other diskettes were totally unreadable by DOS. Since some
of the infected diskettes were original commercial software (the owner
quickly learned the hazards of NOT using write protect tabs and NOT
making backup copies), a simple utility was written to write a DOS
5.0 boot sector to a 1.44Mb diskette. Worked fine, until some 720k
diskettes were found in the batch. At that point, Brect was born.
Brect recognizes only floppy drives A and B and gives you a choice of
which drive will be your working drive. After that, if the infected
diskette can be read by DOS, Brect will automatically recognize the
diskette size and write the appropriate clean boot sector to it.
Unless you have done something stupid with CHKDSK, Norton's Disk
Doctor, or a similar utility, the diskette should be fully functional
and virus free once more. Brect, of course, has no effect on any
infected files that may have been on the diskettes. If that concept
is beyond your comprehension, you have no business trying to remove
any virus from anything.
If DOS cannot read the target diskette, Brect will report the problem.
Pressing <F10> will allow you to force a diskette write, but it's up
to you to select the correct diskette size in that case. Writing a
2.88Mb boot sector to a 720k diskette will definitely not give you a
usable diskette! However, if you do err in your size selection, just
fire up Brect and try again. Sooner or later you should get it
right. If not, I understand needlepoint can be a very satisfying
pasttime.
Brect can recognize and write proper boot sectors to 160k, 180k,
320k, 360k, 720k, 1.2Mb, 1.44Mb and 2.88Mb diskettes. Might have
included the capability to deal with 8-inch floppies, but don't have
an 8-inch drive connected to a DOS machine. Sorry.
Brect writes a NON-system boot sector, meaning that you cannot boot a
computer from a diskette once Brect has written to the boot sector.
If a diskette was originally a bootable DOS diskette, and if you had
to use Brect on it to remove a boot sector virus, you can always put
the diskette in a clean computer and use the SYS command in DOS to
put things back to the original state. If you don't understand what
I'm saying here, you shouldn't be using this program, or any other
software from Zen Works, for that matter.
For the record, Brect writes a very generic boot sector that conforms
to DOS standards as far as the vital data is concerned, but otherwise
makes a determined effort to not infringe on IBM, Digital Research,
Microsoft, or any other DOS vendor's code.
Brect will not react well to being compressed with any file
compression utility, nor will it accept being renamed. Brect does
employ some rudimentary self-checking and will likely refuse to run
if it becomes infected with a virus, or if some other software adds
any "verification bytes" to Brect's code.
Brect is protected by copyright. Brect can be freely distributed and
is free for use by individuals, schools, and hospitals. Use of Brect
in any other commercial or government environment does require a site
licence. Failure to observe that minor stipulation entitles you to
an introduction to our lawyers.
