Why won't it load automatically in auotexec.bat....
I want the boot disk, when it starts, to let me choose to load a program from the CD (CD boot), so I set it in autoexec.bat,
but it doesn't work. When it switches to %CDROM% it says it can't find the drive,
but after I get in, that is, after the A:\> prompt appears, if I type it manually it works.
I've set up a virtual drive; if I first switch to the virtual drive and then switch to %CDROM% it also works, but it can't automatically switch directly to %CDROM%. Can anyone tell me how to do it? Many thanks

Below is the content of auotexec.bat
@ECHO OFF
PATH=A:\;%cdrom%:\system\

set temp=c:\
set tem=c:\

LH MSCDEX.EXE /D:mscd001
LH MOUSE.COM
LH FINDCD.EXE

cd %cdrom%:
cd system\ghost
ghost.exe

Try removing that "CD" command in front.

It should be:
％cdrom％
cd\
cd system
cd ghost
ghost

The following is quoted from 如是大师 at 2003-6-16 23:51:39:
It should be:
           cd\
           cd system
           cd ghost

Why make it so complicated? One line, "CD\SYSTEM\GHOST", is enough..

Explain it clearly..

％cdrom％ should be ％cdrom％:

I'll try it.......
Also, using LH and not using it seems to make no difference, right?

Sorry, I posted the wrong batch file. It should be:
％cdrom％:
cd\
cd system
cd ghost
ghost.exe
This is correct, right? What I mean is: if I add these in autoexec.bat, it still won't work. When it executes to %cdrom%: it says it can't find the drive, but after entering, that is, after A:\> appears, executing commands like this works; or if I set it in autoexec.bat to switch to the virtual drive first and then to %cdrom%:, that also works. It just can't switch directly. What exactly is the problem?
But I'm using Virtual PC for testing, I haven't tried it on a real machine yet.....

Which FINDCD.exe are you using? If it's the one written by WENGIER himself, then don't put a colon after %cdrom%, write it the way Master Rushi did. Because WENGIER's variable already includes the colon. You can use the SET command to check the value of CDROM.
Also, there's no need for your command to be written so complicated. GHOST seems to be just one file. Just do it directly like this:
%cdrom%\system\ghost\ghost.exe

Many thanks to everyone for the enthusiastic help.......
After many tests, it turned out to be a virtual machine problem; because the program was slow, the CD-ROM hadn't finished loading yet.......^^
By the way, I want to make a menu under DOS (an exe one). Is there any simpler tool for that?
