recommend you configure the adapter at the AIX level on the PCI-based server

system in the defined state before setting the right parameters, as in step number

6.8.1 Configuring an ISA Ethernet Adapter

Before the hardware parameters for the new ISA adapter can be selected and

tested using the 40P or 43P firmware, you will have to

tell

AIX the values of these

parameters.

The configuration for ISA Ethernet adapter requires you to specify the Interrupt

Level, the Bus I/O Address, the Bus Memory and the Connection or Media Type.

These parameters can assume the following values:

 Interrupt Level = 5, 7, 9 or 11

 Bus I/O Address = 0x240, 0x280, 0x300, and so on

 Memory Address = 0xc000, 0xc4000, 0xc8000, and so on

 Connection Type = bnc, dix, tp, and so on

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

Defaults Parameters

If this is the first ISA adapter on the system, you may select the default

values:

 Interrupt Level = 11

 Bus I/O Address = 0x300

 Bus Memory = 0X0c0000

 Connection Type = bnc

and go directly to step number 9.

2. If any ISA adapter is installed, check for available Interrupt Level values by

entering the following command:

lsresource -l bus -a | grep bus_intr

This command generates a list of adapters using different Interrupt Levels that

looks similar to the following:

N fda bus_intr_lvl 6 (A)

N sa bus_intr_lvl 4 (A)

N sa1 bus_intr_lvl 3 (A)

N sioka bus_intr_lvl 1 (A)

N sioma bus_intr_lvl 12 (A)

N ampx bus_intr_lvl 11 (A)

N scsi bus_intr_lvl 13 (A)

N ent bus_intr_lvl 9 (A)

3. Select an Interrupt Level that is not currently in use.

4. If any ISA adapter is installed, check for available Bus I/O Address values by

entering the following command:

lsresource -l bus -a | grep bus_io
