Power-On Password

RT/CMOS RAM

has

8

bytes reserved

for the power-on password

and the check character. The 8 bytes are initialized to

hex 00. The

microprocessor

can access

these

bytes only during POST. After

POST is completed, if a power-on

password

is installed,

the

 

password

bytes

are locked

and

cannot be

accessed by

any program.

During power-on password installation, the password (1 to 7 characters) is stored in the security space.

Installing the password is a function of the built-in system program Easy-Setup. The power-on password does not appear on the screen when it is installed, changed, or removed. After the power-on password has been installed, it can be changed or removed only during POST.

The computer also can have a keyboard password. For more

information, see the keyboard and auxiliary device controller section of theIBM Personal System/2 Hardware Interface Technical

Reference.

Other Passwords

In

addition

to the

power-on

password,

the

computer

provides two

more

passwords:

 

 

 

 

 

The hard-disk

password

(HDP)

protects

the

data on

your

removable hard disk drive from being accessed by unauthorized persons.
