		   The DOS Version-Setting Service - DOSVER
				 version 2.50

	PURPOSE:  The user is surely familiar with the message "Incorrect DOS
 version" displayed on the screen.  DOSVER is a handy way to overcome this
 problem.  As you know, MICROSOFT has a similar utility, SETVER. This utility,
 however, has a number of significant shortcomings:
	1) You have to manually set all programs that you want to "deceive";
	2) If you are setting a lot of programs, SETVER takes-up a large
	   amount of memory;
	3) You can't use programs with identical names that need different
	   DOS versions, at the same time;
	4) You can't load and reconfigure SETVER "on the fly".


	SYSTEM REQUIREMENTS:  DOSVER runs on IBM PCs under the MS-DOS
 operational system.

        DISTRIBUTION:  DOSVER is shareware and may be used free of charge for
 one month and distributed without restriction (but only with all of the
 enclosed files). If you want to continue using the program you have to
 register. Registration fee is $10 for private users and $20 for organizations.
 Please see the file REGISTER.HOW for detailed information. It is forbidden to
 modify the program code or utilize the program in any manner whatsoever for
 commercial purposes without the prior authorisation of the author.


 	INSTALLATION: Although loading DOSVER resident without any of the
 optional command-line parameters is adequate to run the program - the default
 values then being applicable - wider possibilities are available to the user
 if the time is taken to become acquainted with these parameters.

 Syntax: DOSVER [/v...] [/f] [/l]

	/vXX.YY  - set a DOS version, XX.YY is a version decimal number;

	/vhXX.YY - set a DOS version, XX.YY is a version hexadecimal number;
           	   For DR-DOS - 67.10, for NovellDOS - 72.10.

	/va      - set automatic requested version control (default).
	           Detect requested version in most cases, although there is a
                   possibility of unsuccesful detection; for example, SI of
                   PCTOOLS.

 	/vo      - set to original version.
		   Usually used if you can't unload DOSVER, but want to
                   disable it.

      	/f       - don't install Latvian font.
		   I load four Latvian letters into video memory to enable my
		   name and that of my city to be displayed in my native
                   tongue. However, if you feel that this feature spoils your
                   pseudo-graphics or clashes with your national character set,
                   you may disable this option.

	/l -       don't draw lines.

 Scancodes may be detected with SCANCODE.COM


	UNINSTALL:  The memory used by DOSVER may only be released if no other
 resident programs have been installed after DOSVER. Should any other resident
 programs have been loaded subsequently, however, then they must first be
 removed before DOSVER can be uninstalled.

 Syntax: DOSVER /u [/f] [/l]

	/f, /l see above...


	REINSTALLATION: If you can't uninstall DOSVER, but you want to change
 some parameters, you can reinstall it.  For reinstallation you have add the
 /r parameter to the installation string.


	OPERATION: When DOS function 30h or DOS function 33h, sub-function
 06h (both - used by MS-DOS) or DOS function 44h, sub-function 52h (used by
 DR-DOS and NovellDOS) is called, DOSVER changes the returned version number.
 If the number is set directly, then it's returned to all callers, except
 COMMAND.COM (because it checks the version number as every command is
 executed). If DOSVER is configured for automatic version detection, then it
 analyzes the caller's code and tries to detect the version (Mickel's from
 Holland algorithm is used).  DOSVER utilizes the PSP, that allows 200 bytes
 of DOS memory to be saved.


	HELP: If you wish to help me to develop and distribute DOSVER,
 there are some ways to do it:
   1) register DOSVER, see REGISTER.WHY and REGISTER.HOW files for detailed
 information;
   2) recommend and give a shareware version of DOSVER to your friends;
   3) put a link to DOSVER home page on your Web site, see file LINK.TXT
 for detailed information;
   4) upload DOSVER to all DOS and Windows shareware FTP and WWW collections
 you know, see file UPLOAD.TXT for detailed information;
   5) write about DOSVER to newsgroups, mailing lists and forums, where
 people can have an interest about it;
   6) let me know about bugs, problems and suggestions.
