IBM RS/6000 - Manual (Page 155)

Shared Bus Memory Address = 0xc0000, 0xc4000, 0xc8000, and so on
Length in shared bus memory = 8 KB, 16 KB, 32 KB, 64 KB
Address of bus memory for BIOS = 0xc8000, 0xca000, 0xcc000, and so on
Ring Speed = 16 MB, 4 MB
1. Check if there are any ISA adapters that are already installed in your computer,
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 = 9
Bus I/O Address = 0xa20
Shared Bus Memory = 0X0d0000
Length in shared bus memory = 0x8000
Address of bus memory for BIOS = 0xcc000
Ring Speed = 16 MB
and go directly to step number 11.
2. If any ISA adapter is installed, check for available Interrupt Level values by
entering the following command:
lsresource -l bus -a | grep 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 tok intr_level 7 (A )
N ampx bus_intr_lvl 11 (A )
N scsi bus_intr_lvl 13 (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
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 sa bus_io_addr x 3f8 - x 3ff
O sa1 bus_io_addr x 2f8 - x 2ff
O sioka bus_io_addr 1 x 6
O sioma bus_io_addr 1 x 6
O ppa bus_io_addr x 3bc - x 3be
O tok bus_io_addr x a2 - x a23
O ampx bus_io_addr x 2a - x 2a6
O scsi bus_io_addr x 1 - x 1 ff
