6.4.2 Configuring the Adapter
The following procedures apply to every PCI-based RS/6000 system that supports
the 8-Port Asynchronous ISA Adapter
1. Check if there are any ISA adapters that are already installed in your computer
by using the following command:
lsdev -Cc adapter -s isa
Default Parameters
If the 8-Port Asynchronous ISA Adapter is the first ISA adapter of this type
installed into your system, you may use the default bus I/O address of
x324
.
2. If any ISA adapter is installed, enter the command:
lsresource -l bus -a | grep bus_io
This command generates a list of adapters using bus I/O that looks similar to
the following:
O
fda
bus_io_addr
