tem use.

Extended Memory

, which has no user-selectable
EXTENDED MEMORY
options, indicates the amount of memory available as
extended memory. The value given is in megabytes rather
than kilobytes. To convert megabytes to kilobytes, multi-
ply the megabyte total by 1024.

Reserved Memory

allows you to designate a region of
RESERVED MEMORY
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 option in the
15M - 16M
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 to 16 MB
comes from the memory expansion card.

CPU Speed

CPU SPEED
system boots.
Press the left- or right-arrow key to toggle the
category between the resident microprocessor's

which lets you accommodate speed-sensitive application
programs. A change to this category takes effect immedi-
ately (rebooting the system is not required).

Num Lock

determines whether your system boots with
NUM LOCK
the Num Lock mode activated on 101- or 102-key key-
boards (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 labels on the bottom of
each key.

Keyboard Errors

enables or disables reporting of key-
KEYBOARD ERRORS
board errors during the power-on self-test (POST), which
is a series of tests that the system performs on the hard-
ware 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 have no permanently attached
keyboard. In these situations, selecting
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 one is attached to the computer.

System Password

displays the current status of your
SYSTEM PASSWORD
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
