RE: [Openipmi-developer] Fail to load ipmi_si on HP CX2600

Aaron,

To find the correct address to hand-specify, it seems that you will have
to refer to the HP platform specification, since the common addresses
and discovery methods don't work.

If there is invalid data in the ACPI tables, then it is fairly hard for=20
the driver to do anything right automatically.

You will need to hand-specify the parameters for the interface.  You can

read the IPMI docs in Documentation/IPMI.txt and it details this pretty=20
explicitly.
