Removing an Expansion Card

Follow this general procedure to remove an expansion
card:
1. If you are removing a non-Plug and Play ISA
expansion card, enter the ICU and remove the
expansion card from your configuration.
See Chapter 3, "Using the ISA Configuration Util-
ity," for instructions.
2.
Remove the computer cover as instructed in
"Removing the Computer Cover" in Chapter 5.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.
3. If necessary, disconnect any cables connected to
the card.
4. Remove the expansion-card cage as instructed in
"Removing the Expansion-Card Cage" in Chap-
ter 5.
5. Position the expansion-card cage so that the riser
board lies horizontally on your work surface, and
unscrew the mounting bracket of the card you
want to remove.
6. Grasp the card by its outside corners, and ease it
out of its connector.
7. If you are removing the card permanently, install
a metal filler bracket over the empty card-slot
opening.
NOTE: Installing filler brackets over empty card-
slot openings is necessary to maintain Federal
Communications Commission (FCC) certification of
the system. The brackets also keep dust and dirt out
of your computer.

instructed in "Replacing the Expansion-Card
Cage" in Chapter 5.
9. Replace the computer cover, and then reconnect
your computer and peripherals to their power
sources and turn them on.
A
dding Memory
Memory can be increased to a maximum of 256 mega-
bytes (MB) by installing combinations of 16-, 32-, 64-, or
128-MB dual in-line memory modules (DIMMs) in the
two DIMM sockets on the system board. Figure 6-6
shows the DIMMs and DIMM sockets.
Your system can support nonparity extended-data out
(EDO) DIMMs.
