I have several programs that will not work with the new version of MS-DOS.
I already tried the "setver" command but it doesn't help. Are their any
other tricks that I might try to make these programs run? Two programs that
I'm specifically having trouble with are Norton's Disk Cache and DoubleDos
V5.0 although their are several others... Thanks in advance,
William Moxley

Thanks in advance Are you sure DOS 5.0 is the only reason ? Norton's Disk Cache works perfect with DOS 5.0 here. Did you remember to reboot after issuing the SETVER command?

When Microsoft put in the setver command, they probably intended for it to circumvent two situations: (a) when programs are far more sensitive to DOS versions than they really need to be, DOS external utilities like XCOPY will simply *NOT* run under any other version of DOS, even though the version number should not matter to XCOPY unless it is less than 2.x in which case subdirectories don't exist {grin}. (b) more importantly, programs which need certain DOS services or functionality which are only available after a certain version of DOS; subdirectories with 2.x, for example, but some others as well which are not visible to the end user but only to programmers. If programmers for an application were sloppy and onl*ONLY* checked to see if the current DOS version is 3.x or 4.x and if not, *AUTOMATICALLY* assumed that they were running on 2.x or {heaven forbid} 1.x and quit, this would make a lot of users of such an application unhappy. Hence SETVER to make your DOS look like some other version of DOS. In your case, the programs which you cite are very low-level programs, one being a disk cache and the other being a multitasker. While I don't know if they fall into category B or not, these are exactly the kind of programs which really *DO* need to know what version of DOS they're actually running under, because they often peek under the hood. Microsoft did their best to make DOS 5.0 compatible with widely available programs (including continuing to implement undocumented DOS functions which were commonly used), but even so, in the case of DOS 5.0, peeking under the hood in a non-standard fashion might leave you looking at nothing, since some of DOS now sits in high memory blocks and HMA. If you cannot get such low-level programs to run natively under 5.0, you can try blindly running them with SETVER, but I would recommend a quick call to the manufacturer support line to check compatibility. -- Singing off, UNIX:/etc/ping instantiated (Ping Huang)

If this is really necessary (what I doubt) what shall I do if I have one program that needs version 5 and another one that refuses to work unless it is running on a specific dos version. Do I have to boot every time I want to switch between these two programs?

Great! SETVER works on a program name basis: the fake version number it returns is a function of the name of the program which issued the return-version- number interrupt. Thus, you can have MSCDEX.EXE think it's running on DOS 4.00 while VDISK.SYS believe that we're still running DOS 3.3. Joe Morris

Great! >-- NO! NO! NO!. Read your MSDOS 5 manual please. If you haven't got your upgrade yet then here's how setver works. 1. In CONFIG.SYS you say device=[drive:][path]setver.exe. This will need just one reboot! Setver is now installed and keeps a 'lie table'(NB not one for sleeping/doing-others-things on) which will permit up to about 30 entries. 2. Having rebooted type setver and you will get a listing of the lie table which may well already have some entries after an upgrade install - the install may well have put setver into config.sys. 3. Now if you have a program that needs to think its running under an earlier version of DOS then say 'setver [drive:path]filename n.nn' where n.nn is the DOS version that is the lie. This updates setver's table which is kept across boots until you say 'setver [drive:path]filename [/delete[/quiet]]'. 4. NB****** For the updated table to take effect you need to reboot BUT the info entered is NOT lost - and of course you can have more than one program in the lie table!!!!!!!!!! 2. -- Andrew Turner act@csc.canberra.edu.au Die, v: To stop sinning suddenly. -- Elbert Hubbard

Great! > -- > Nope ! SETVER is program specific. I think the syntax is: SETVER <setver program directory path> <Your program name> <ver number> So, SETVER only report an altered version number to the program you specified. Not to every program.
