Deleting a Power-on Password
To delete your power-on password, follow these steps:
1. If you do not have a hard disk, insert your Startup diskette
in drive A.
2. Turn on or reset the computer. At the key prompt, enter
your current password followed by a forward slash. For
example, if your password is 123, type:
1 2 3 /
3. Press Enter. A happy face character appears and then the
computer loads MS-DOS.
The next time you turn on or reset the computer, it does not
request a password and loads MS-DOS immediately.
Note
You need to know the password in order to delete it using this
method. If you do not know the password, see “Password
Problems” in Appendix D.
