I can't remember if 0.82pl3 even supports that. Like I said, I never use 0.82pl3, only newer 0.84-pre2, but some people still prefer it. > Suppose I have a SETUP.BAT at D:\ , thus D:\SETUP.BAT > > It shouldn't matter if I do: > 1) D:\SETUP > 2) D:\SETUP.BAT > 3) D: ; SETUP > 4) D: ; SETUP.BAT > 5) D:SETUP (though I'd better be in correct dir on D: before) > 6) D:SETUP.BAT > 7) SET PATH=%PATH%;D:\ ; SETUP > 8) SET PATH=%PATH%;D:\ ; SETUP.BAT > 9) D: ; \SETUP > > In all cases I want SETUP.BAT to be able to switch current directory to > whereever this file SETUP.BAT itself is contained, thus D:\ Is the problem that we don't know what drive the CD will be assigned? 'Cause I (dumbly) was thinking, "Well, he knows it's D:\, so he should just 'set SETUP=D:\' in the .BAT". I guess a silly "for %%a in (c d e f g) do if exist %%a:\setup.bat set SETUP=%%a" is probably out too, hmmm? ;-) Bah, confusing. A standalone tiny util for this purpose would probably work better. I also had written a silly WHATDRIV.COM util used on one of my floppies, but I can't remember why. Maybe I was expecting someone to convert to .ISO (mkbiso) or whatever.

For sure 4DOS is more useful, but it might be overkill here. I don't know if Jim would prefer FreeCOM exclusively instead or not (though I probably would). > My FreeCOM part looks like this now: > set /E thisfile=truename %0 > if exist %thisfile%.bat set thisfile=%thisfile%.bat > if exist %thisfile% goto switchdir > for %%x in ( %path% ) do if exist %%x\%0 set /U thisfile=%%x\%0 > for %%x in ( %path% ) do if exist %%x\%0.bat set /U thisfile=%%x\%0.bat > if exist %thisfile% goto switchdir > echo Fail! Looks good, mostly like I would do. Be aware that "for %%x in ( %path% )" won't work in 4DOS (last I tried), nor Win32's CMD (worse, probably due to LFNs and/or spaces). > The difficult part is Microsoft's command.com as it lacks a lot of > variables and concurrent directory/drive switching. Variables such as what? I'm not sure why you'd try using their shell here, perhaps installing from within Windows?? I think Win32's CMD.EXE supports "%CD%" instead of "%_CWD%" and "cd /d" instead of "cdd", if that's what you meant. > Just as the 1.44MB bootdisk I uploaded should work with FreeDOS 1.1 CD > (but doesn't yet, in my uploads), so should any other bootdisk. Good luck! (Sadly I'm not much use testing right now, though I did manually install FreeDOS the other day and auto-installed PuppyLinux. Yeah, even my other P4 computer now has PSU problems [randomly turning on and off], so I'm back to this new one, where Windows hosed itself. Sometimes I hate computers.) ------------------------------------------------------------------------------ 5 Ways to Improve & Secure Unified Communications Unified Communications promises greater efficiencies for business.
