Reserved Memory
Reserved Memory allows you to designate a region of
system board memory that can be supplied by an expan-
sion card. You should not enable the reserved memory
feature unless you are using an expansion card that
requires special addressing.
For example, you may have a memory expansion card
that needs to be addressed starting at 15 MB. Selecting
the 15M-16M option in the Reserved Memory category
specifies that only part of the base memory comes from
the dual in-line memory modules (DIMMs) on the sys-
tem board, whereas the base memory from 15 MB to
16 MB comes from the memory expansion card.
The Reserved Memory category has the following
options:
•
None (the default option)
•
15M-16M
•
512K-640K
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 processor's rated speed (the
default) and a lower compatibility speed, which lets you
accommodate speed-sensitive application programs.
Num Lock
Num Lock determines whether your system boots with
the Num Lock mode activated on 101- or 102-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, each key provides the
cursor-control function (if any) indicated at the bottom of
the key.
Keyboard Errors
Keyboard Errors enables or disables reporting of key-
board errors during the 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 serv-
ers or host systems that do not have a permanently
attached keyboard. In these situations, selecting Do Not
Report suppresses all error messages relating to the key-
board or to the keyboard controller during POST. This
option does not affect the operation of the keyboard
itself, if one is attached to the computer.
System Password
System Password displays the current status of your sys-
tem'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 detailed 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
Password Status provides an extra measure of system
security by letting you set the system password to Locked
or Unlocked.

Password Enabled
When this category is Unlocked, any user who already
knows the system password can disable the password at
system start-up by using the <Ctrl><Enter> option dis-
played on the screen—thus (inadvertently or not) leaving
the system without password protection.
