Instruction Manual

Having the previously installed adapter parameters documented allows better
planning for the installation of additional ISA adapters and enables you to start with
a set of conflict-free definitions. To obtain a list of ISA adapters already configured
in your system, enter the following command:
lsdev -Cc adapter -s isa

The following procedures show you how to obtain the parameter settings of already
installed ISA adapters. If AIX is up and running, you may first want to record the
settings at AIX level for all your ISA adapters before shutting down and
powering-off the system. If the system is powered off, you may first inspect the
settings at hardware level by looking at the switches, or inspect them at firmware
level by using System Management Services.
You can display the relevant parameters of configured adapters either by using the
odmget, the lsattr or the lsresource command.
The lsresource command lets you display the currently assigned values for the bus
resource attributes for the device specified by the given device logical name (-l
Name). Use the -a flag to display the currently assigned values for all bus resource
attributes for all devices under the same parent bus as the specified device.
For example, to display the attribute values set for the device ampx, you can enter
the following command
lsresource -l ampx -s isa
