User's Manual
This could mean
that the mainboard's
current settings
are not the
same as
the defaults
shown
in this manual. Your system manual may
have
additional information
on how the mainboard
should
be
set
up.
If
you want to change
the
existing configuration, consult all of
your system documentation.
Be
certain
that
opening
up

expansion
cards or additional peripheral equipment.

manual provides
all
the information
you
need to upgrade
or change
the
setup of

confident of
your
ability
to work
on
the
computer yourself, ask your
dealer
or a
quali-
fied teclmician
to
do
it
for you.
