Aptiva - Disabling F5, F8; Not allowing AUTOEXEC.BAT & CONFIG.SYS to be bypassed

Applicable to: United States

MS-DOS 6.0 allows you to bypass both AUTOEXEC.BAT and CONFIG.SYS by pressing the F5 key as you are starting your computer. This can disable the effectiveness of some password-protection schemes.

In order to disable this feature, add the following line to CONFIG.SYS: SWITCHES=/N. This line disables both the F5 and F8 keys, which allow you to modify your startup configuration during the boot process.

NOTE
This line can be placed anywhere in CONFIG.SYS.
