I know this probobly belongs on the Windows board, but it's more or less universal. I have a simple dos program I wrote that asks for a password, returning only if the correct password is entered. I put this program in my autoexec.bat file, guessing it would run during bootup. From what I can tell, it doesn't run, or at least the boot doesn't wait for it to return. I know it must work, though, because when I run autoexec.bat in windows, it runs the program. Yes, the program runs in true dos; not console.
