hello, first sorry for my english cause i come from germany. After 4 days of reading topics in forums i have made my stick so how i dream it (Multiboot with extras). But now i have some little problems to start a program that i init in menu.lst I trying the second day, but it will not work cause i am not a linux freak...... I put some isos and the lines for menu.lst that works great, but i have a dos program that i need permanently and i downt know how i can start it. I tried it with making a iso, but after it boots to dos come an error cause the autoexec search a cd in x:. The Dos-prog isnt large (1MB) but I cant pack it to a floppy image, cause out of space by 1,44MB when i make a bootable dos image. I have tried with virtual floppy to make a 1,72MB or 2,88MB floppy image, but i cant format it in xp, it hangs and do nothing. So my questions are..... Can anybody tell me what entry i need in menu.lst to start a Dos-prog that i have in the folder "images" in the root of USB? Or can anybody tell me what i must write in the AUTOEXEC.BAT to start the dos-prog from the "image"-folder after the Floppy-image boots to Dos? Or what entry i need in the AUTOEXEC.BAT for X: that the iso can boot the Prog? The orig AUTOEXEC.BAT from the Prog that is on a cd has this entries.... ---------------------------------------------- @echo off echo. Dos-Prog 8.05 PATH A:\ SET DIRCMD=/O:GN /L LH A:\MSCDEX.EXE /D:OEMCD001 /L:X a:\my\mouse.com x:\my\Dos-prog.exe ------------------------------------------------ I hope for some answers.....
