Cache sets the state of the processor cache to On (default) or Off.
Num Lock determines whether your system boots with the Num Lock mode acti-
vated 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 pro-
vides 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.
Speaker determines whether the built-in speaker is On (the default) or Off. Rebooting
the system is required for the changes to take effect.
OS Install Mode determines the maximum amount of system memory available to
the operating system. When it is set to On, the maximum amount available is
256 MB; when it is set to Off (the default), all system memory is available to the oper-
ating system.
Processors 1, 2, 3, and 4 display the version or stepping number of each processor
slot in the system. These options have no user-selectable settings.
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 option is useful when applied to self-starting servers or host systems that have
no permanently attached keyboard. In these situations, selecting Do Not Report sup-
presses 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.
Boot Sequence can be set to Diskette First (the default) or to Hard Disk Only.
The term boot refers to the system's start-up procedure. When turned on, the
system "bootstraps" itself into an operational state by loading into memory a
small program, which in turn loads the necessary operating system. Boot
Sequence tells the system where to look for the files that it needs to load.
