below the 15-MB address comes from the dual in-line
memory modules [DIMMs] on the system board).
The Reserved Memory category has the following
options:
•
None (the default option)
•
512K - 640K
•
15M - 16M

CPU Speed

CPU Speed indicates the processor speed at which your
system boots.
Press the left- or right-arrow key to toggle the CPU
Speed category between the resident microprocessor's
rated speed (the default) and a lower compatibility speed,
which lets you accommodate speed-sensitive application
programs. A change to this category takes effect
immediately (rebooting the system is not required).
You can also toggle between the rated processor speed
and the compatibility speed while the system is running
in real mode by pressing <Ctrl><Alt><\>. (For
keyboards that do not use American English, press
<Ctrl><Alt><#>.)

Num Lock

Num Lock determines whether your system boots with
the Num Lock mode activated on 101- or 102-key
keyboards (it does not apply to 84-key keyboards).
When Num Lock mode is activated, the rightmost bank
of keys on your keyboard provides the mathematical and
numeric functions shown at the tops of the keys. When
Num Lock mode is turned off, these keys provide cursor-
control functions according to the label on the bottom of
each key.

Keyboard Errors

Keyboard Errors enables or disables reporting of
keyboard errors during the power-on self-test (POST),
which is a series of tests that the system performs on the
hardware each time you turn on the system or press the
reset button.

This category is useful when applied to self-starting
servers or host systems that have no permanently
attached keyboard. In these situations, selecting Do Not
Report suppresses all error messages relating to the
keyboard or to the keyboard controller during POST.
This option does not affect the operation of the
keyboard itself if a keyboard is attached to the
computer.

System Password

System Password displays the current status of your
system's password security feature and allows you to
assign and verify a new password. No one can assign a
new password unless the current status is Not Enabled,
which is displayed in bright characters.
The options for the System Password category are:
•
Not Enabled (the default option)
•
Enabled
•
Disabled by Jumper
NOTE: Read "Using the System Password Feature"
found later in this chapter for instructions on assigning a
system password and using or changing an existing
system password. See "Disabling a Forgotten Password"
found later in this chapter for instructions on disabling a
forgotten system password.

Password Status

When Setup Password is set to Enabled, Password Status
allows you to prevent the system password from being
changed or disabled at system start-up.
To lock the system password, you must first assign a
setup password in the Setup Password category and then
change the Password Status category to Locked. In this
state, the system password cannot be changed through the
System Password category and cannot be disabled at sys-
tem start-up by pressing <Ctrl><Enter>.
To unlock the system password, you must enter the setup
password in the Setup Password category and then
change the Password Status category to Unlocked. In this
state, the system password can be disabled at system
start-up by pressing <Ctrl><Enter> and then changed
through the System Password category.
