   README.TXT -- This file

   The C sources are written for Borland Turbo C 2.0 and could require even
a lot of work to be compiled with different versions of C. They are plain C
and maybe could be easily translated in assembler, because  they  don't use
tipical C functions.

CHKPTBL.C - CHKPTBL.COM
 This program compares the root sector  (that is partition  table for
 hard disks and boot sector for floppy disks)  and, optionally (in the
 case of an hard disk), the boot sector with data stored in a supplied
 file.
  The data files could be generated always with this same program.
  A lot of options allow a full control of program,  but has to be re-
 membered that such a program works at an intimate level with the com-
 computers hardware and so its use must be very careful. No warranties
 are given and the author could not be claimed responsible for damages
 produced by the use of the program.
  One possible use of this program is to save root and boot sector  of
 the hard disk and check them every boot  (inserting a command in  the
 autoexec.bat file) to reveal undesired changes (maybe a virus) and e-
 ventually, with maximum care, restore the original data.

  syntax:
  CHKPTBL [switches] <file-name>
    <file-name> is the data file to compare root sector with.
          If no extension is present extension .TBL is added, if a di-
         rectory name is supplied (ending with '\')  the default  name
         PARTTBL.TBL is used. If no name is supplied no check is made.

    switches:

    /H[1..Number of physical hard drive - default 1] selects the  phy-
         sical hard drive subsequent commands refer to.
          For default hard drive 1 is taken.
    /F[1..Number of physical floppy drive - default 1]selects the phy-
         sical floppy drive subsequent commands refer to.
          If /F with no number is specified physical floppy 1 is taken
    /S    Stop if differences are found between data stored in the fi-
         le and actual root (boot) sector.
    /C    If differences are found between data stored in the file and
         actual root (boot) sector, correct them restoring the data in
         file.
    /B[+|-] Set the "Check boot sector too" option true(/B+) or  false
         (/B-).  If this switch is not specified the option is  false,
         if only /B is specified the option is set to true.
    /W[+]<file-name> Store drive-data to <file-name> (ext. and name as
         for reference file).   If the file already exists, if  /W+ is
         specified the file is overwritten, otherwise nothing is done.
          If the "Check boot sector too" option  is actually true  and
         the actually selected drive is an hard whose partition number
         one is a dos bootable partition even the boot sector is saved
         (for a total of 1024 bytes),otherwise only the root sector is
         written to the file.

  example:
  CHKPTBL /Wfile1 /B /H2 /Wfile2/F/Wfile3 /H/Wfile4 C:\DOS\
    Actions:
    The root sector of hard drive 1 is written to file1, the root sec-
   tor of hard drive 2 (which is generally a not dos-bootable disk) is
   written to file2, the root sector (which is the boot sector) of the
   floppy drive 1 (usually a:) is written to file3 and the root sector
   and the first partition's boot sector (if it's a DOS-bootable  par-
   tition) of the hard drive 1 are written to file4 and both are  com-
   pared with the file C:\DOS\PARTTBL.TBL.

  Note: If the program has to be recompiled, the tiny model has  to be
 used and the resulting .exe has to be converted in .com (with the DOS
 utility EXE2BIN for example) or the program doesn't work.
