Note:
The on and off DIP-switch selections are set by switching them down and
up , respectively. The mapping is:
off = up
on = down

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 x3f - x3f5
O fda bus_io_addr2 x3f7
O ppa bus_io_addr x3bc - x3be
O sa bus_io_addr x3f8 - x3ff
O sa1 bus_io_addr x2f8 - x2ff

O sa2 bus_io_addr x14 - x17
O scsi bus_io_addr xf - xfff
O scsi1 bus_io_addr x1 - x1ff
3. Select a Bus I/O Address that is not currently in use.
