top.
• Select the I/O base address for the adapter using the following
settings. Refer to Figure 2-2 on page 2-4, and Table 2-1 below.

The I/O base address can be reset after the adapter has been
installed. However, the new I/O base address must be entered into
your network driver's configuration. Note that only two base
addresses, 0A20 and 1A20, can be used if you are running IBM's
PC LAN Program or other NetBIOS-based applications. Refer to
the Network Software Installation Guide for more information.
If an incompatibility exists in the clock source, and you need to set
the adapter for the synchronous clock source mode, proceed to
Section 2.3.2 which follows. If you are installing the adapter in any
other AT-compatible machine, proceed to Section 2.4 to begin
installation procedures.
