Aptiva - What to do if computer "hangs" after changing boot files

Applicable to: United States

DOS revisions beyond MS-DOS 6.0 (including IBM PC DOS 6.3 and PC DOS 7.0) contain two functions that can help you correct this problem. The first function lets you boot the computer while bypassing the CONFIG.SYS and AUTOEXEC.BAT files. The second function lets you confirm each startup command in your CONFIG.SYS file. You then have the option of running the AUTOEXEC.BAT file or bypassing it. In MS-DOS 6.0, there is no option for stepping through the AUTOEXEC.BAT file as it is processed. However, with MS-DOS 6.2x, you can also step through the AUTOEXEC.BAT file.

Bypassing the CONFIG.SYS and AUTOEXEC.BAT files when you start your computer allows it to boot with a minimal configuration. To do this, use the following steps:

1. Start or reboot your computer.
2. MS-DOS displays the message "Starting MS-DOS...." When this text appears, press and release the <F5> function key or press and hold down the SHIFT key. [In Windows 95 hit the <F8> key for a menu.]

NOTE: A minimal configuration does not load device drivers; as a result, some devices (such as the mouse) may not function. If you use a third party disk-compression program (such as Stacker[R]), you should use the <F8> function key during startup, as discussed below. This is not necessary if you use the Microsoft DoubleSpace or DriveSpace program.

If you receive the error message "Bad or missing command interpreter" when you start the computer, type the full path to the COMMAND.COM file and press <ENTER>.

As an alternative to pressing <F5> and skipping the CONFIG.SYS and AUTOEXEC.BAT files completely, you can press <F8> and confirm the loading of each command in the CONFIG.SYS file. To do this, use the following three steps:

1. Start or reboot your computer.
2. MS-DOS displays the message "Starting MS-DOS...." When this text appears, press and release the [F8] function key. This displays your CONFIG.SYS file one line at a time. To process the displayed command, press Y; to bypass the command, press N.
3. After you have processed all the lines in the CONFIG.SYS file, the following command appears on your screen:
Process AUTOEXEC.BAT [Y/N]?
To bypass the AUTOEXEC.BAT file, press N.
To process the commands in the AUTOEXEC.BAT file, press Y.

** MS-DOS 6.2x: The AUTOEXEC.BAT file will then be displayed one line at a time. To process the displayed command, press Y; to bypass the command, press N.
