Option Installation 3-5
ISA expansion slots support industry-standard 8-bit or 16-bit expansion boards. The
PCI/ISA slot also supports PCI expansion boards.
PCI expansion boards run at the system’s processor speed. The PCI bus handles 32 bits of
data at a time, being wider as well as faster than the standard ISA bus. PCI boards can send
and receive data much faster which boosts system performance.

Expansion Board Installation
Install expansion boards in the system as follows.
1.
Remove the system unit cover as previously described.
2.
Follow any preinstallation instructions that came with the expansion board (such
as setting switches or jumpers on the board).
3.
If installing a board in the inside expansion slot (next to the power supply), see
“Inside Slot Expansion Board Installation.” Otherwise, continue to the next step.
4.
Remove the screw securing an expansion slot cover and remove the cover (see
Figure Section 3-6).
Save the screw for installing the expansion board. Save the slot cover for future
use.
