Preparing the EVM Board for Installation
The EVM board has two switches that identify your system’s I/O address
space. Before you install the EVM board, you must be sure that the board’s
switches are set to correctly identify the I/O space that the board can use. You
can change these switch settings to identify the I/O address space that the
EVM uses in your system.
Figure 1 shows where these switches are on the EVM board and identifies the
switch numbers.

The switches are shipped in the default settings shown here and described in
Table 1. If you use an I/O space that differs from the default, change the switch
settings. Table 1 shows you how to do this.
In most cases, you can leave the switch settings in the default position.
However, you must ensure that the EVM I/O address space does not conflict
with other bus settings. For example, if you have installed a sound card in your
system, you may not be able to use the default switch settings for the I/O
address space—the sound card might use this space.
See your PC technical reference manual and your other hardware-board
manuals to determine if there are any I/O space conflicts. If you find a conflict,
use one of the settings in Table 1
.
