2.3 Quick Start
Once the AIC26EVM has been unpacked and you have verified that the board
is configured as shown in Table 2−1, install the software.
Place the CD-ROM into your PC’s CD-ROM drive. Locate the Setup program
on the disk and run it. The Setup program installs the AIC26EVM software on
your PC. Note that if you are running Windows

2000 or XP, you need admin-
istrator privileges to install the software. Follow the instructions that the install-
er gives you.
When the installation is complete, connect a USB cable from your PC to the
AIC26EVM. You may see a message that a Human Interface /Audio Device
has been connected. Once this connection has been made, launch the
AIC26EVM software on your PC.
The software should automatically find the AIC26EVM. If the board is found,
the screen shown in Figure 2−1 appears.
