Also, if you plan to work with more than one piece of
hardware, you can avoid repeated steps if you follow the
recommended order for hardware changes.
Keeping in mind that you also need to follow the
instructions that came with your new hardware, follow
these steps when you upgrade or replace your
hardware:
1.
If you install hardware that meets one or both of
the following criteria, turn on your computer:
•
Might create a system resource conflict with an
installed Mwave adapter card
•
Might create a system resource conflict with an
installed Plug and Play card
Otherwise, skip to step 4.
2.
If you install hardware that might create a resource
conflict with an installed Mwave adapter card,
follow the instructions in "Resolving Mwave
resource conflicts" on page 73. Complete your
work in the Windows 95 Device Manager.
3.
If you install hardware that might create a resource
conflict with an installed Plug and Play adapter
card, follow the instructions in "Resolving Plug
and Play resource conflicts" on page 76. Complete
your work in the Setup Utility.
4.
Turn off your computer and remove the system
unit cover as instructed in "Opening the system
unit" on page 58.
5.
Complete your hardware changes as instructed in
"Chapter 6: Adding and replacing system board
components" on page 61 and "Chapter 7: Adding
and removing adapter cards and drives" on
page 73.
6.
Reassemble your computer.
7.
Turn on your computer. If you receive any
messages telling you to check the Setup Utility,
follow the instructions in "Updating the Setup
Utility" on page 72 if you worked with system
board components. If you worked with adapter
cards or drives, follow the instructions in
"Updating the Setup Utility" on page 119.
If you plan to make more than one hardware change
while you have the system unit cover off, make changes
in the following order:
1.
Make all changes on the system board.
2.
Add or replace any drives.
3.
Add or replace any adapter cards.
To access some hardware components, you must first
remove other hardware components. For instance, if
you add system memory to a desktop system, you
might have to remove one or more adapter cards to
access the memory sockets on the system board. If you
add system memory to a minitower system, you will
have to remove all adapter cards and the riser card to
access the memory sockets on the system board.
If you follow the recommended order for hardware
changes, you will not need to remove components you
just added to access another component.
