how to declare the autoexec.bat

[tungnt]

Dear everybody,

Please help me to declare in autoexec.bat.

I plan to make a bootable Win98SE Cd that when it boots, it will automatically run a program. I know how to make a bootable CD but I don't know how to declare in autoexec.bat because this CD when run on this PC, the CD drive may be drive E but when run on other PC, the CD drive may be F.

Therefore, I don't know how guide the CD to define exactly the execute file located.

I don't use the image file because this program is bigger than 5 MB.

Anybody knows, please help me

Thanks a lot

Tung

try FINDCD.EXE (search for it). it basically debug's the system and sets a %CDROM% to whatever it ....well finds

you could do it the old generic way, slow but since your cdrom will be probably D:-H: you could make a file somewhere on the cd and do...

IF EXIST "E:\thiscd.txt" SET %CDROM% = E:
IF EXIST "E:\thiscd.txt" SET %CDROM% = F:
IF EXIST "E:\thiscd.txt" SET %CDROM% = G:
IF EXIST "E:\thiscd.txt" SET ...
get the picture? If not search and read.

errr..

IF EXIST "E:\thiscd.txt" SET CDROM=E:
IF EXIST "E:\thiscd.txt" SET CDROM=F:
IF EXIST "E:\thiscd.txt" SET CDROM=G:
IF EXIST "E:\thiscd.txt" SET ...
get the picture? If not search and read.

errr AGAIN!!!

IF EXIST "E:\thiscd.txt" SET CDROM=E:
IF EXIST "F:\thiscd.txt" SET CDROM=F:
IF EXIST "G:\thiscd.txt" SET CDROM=G:
IF EXIST "H:\thiscd.txt" SET ...
get the picture? If not search and read.

Is the program that you want to run on the CD?
just declare it after loading CD drivers without mentioning any CD drive letter, ie:

@echo off

smartdrv.exe

MSCDEX.EXE  /D:tomato /L:X
ghost.exe

I use this on my recovery CD, to run Ghost, without having to type anything.
