Removing a Password
If you have forgotten your password and you do not want to set
a new one, there are two ways to remove the current password:
LI
Disable the existing password
Ll
Disable the password function.
To do either of these procedures, you must reset a jumper on the
main system board.
You should disable the existing password if you want to be able
to set a new password later without having to reset a jumper on
the main system board again. See “Disabling an existing
password” below for instructions.
If you disable the password function, you cannot set a new
password unless you perform the steps to disable the existing
password at that time. If you do not want to use a password
anymore, follow the instructions under “Disabling the password
function” below.
Disabling an existing password
If you do not know your power-on password and do not want to
set a new one, follow these steps to disable the existing
password:
1.
Turn off the computer and follow the instructions under
“Changing Jumper Settings” in Chapter 5 to enable the
password skip function by setting jumper J2 to position 1-2.
2.
Insert the Reference diskette into Drive A and turn on the
computer. You do not see the key prompt (
C+rrn
).
