Installing an expansion card
The Macintosh comes with a slot inside called a processor
-direct
slot in which you can install a processor
-direct expansion card for
special purposes. Some expansion cards are designed so that you can install them yourself
. Others can be installed only by an Apple-
authorized representative. T
o install a card, use the
documentation supplied with the card you plan to install, or follow the instr
uctions in this section.
s
Wa
rning:
If you have installed a floating-point unit (FPU) on
the main logic board of your Macintosh, do not install an expansion card that also contains one. If you have two FPUs, your Macintosh may not work properly
.
s
s
Wa
rning:
To
avoid damaging your computer and expansion
card, do not attempt to install any expansion card without first
checking the documentation for that card. If the
documentation specifies that an Apple-certified technician must install the card (usually because the
installation requires
special training or tools), consult the ser
vice and support
infor
mation that came with your computer for instr
uctions on
how to contact an Apple-authorized ser
vice provider or Apple
for assistance. If you attempt to install the card yourself
, any
damage you may cause to the computer or card will not be covered by the limited war
ranty on your computer
. If the card
is not an Apple-labeled product, check with an Apple- authorized dealer or ser
vice provider to see if you can install it
yourself
.
