Chapter 2. Starting DOS > Project: Controlling the Boot Process

Project: Controlling the Boot Process

Users who practice safe computing should make sure that they have a floppy-based boot disk before messing with either CONFIG.SYS or AUTOEXEC.BAT. Fortunately, the DOS development team has made this practice less necessary. A new feature introduced in DOS 6.0 enables you to use function keys to exercise control over the boot.

Imagine, for example, that you have just edited AUTOEXEC.BAT to load a program during bootup. For whatever reason, this program is incompatible with your system, and the computer simply freezes each time the command is run. You can never get to a DOS prompt to edit the file because the machine hangs every time. You can boot off your floppy boot disk, of course, but now you have an easier way.
