Sorry to get your hopes up and then dash them :-). It should work, the
IPMI driver will work with an IPMI 0.9 system. I looked in the technical
specifications for the board, but I didn't see any useful information
about port numbers or such.
A couple of things to try:
* Try loading without any parameters. That will use the defaults,
which are generally correct.
* Try loading with ports=0xca2. I suspect that's the actual port,
not 0xca0, since that's the default KCS address.
* Try upgrading your firmware (BIOS and on the BMC) if it's not
already current.
* This is a little more desperate, but you can try playing around
with the register spacing, shift, and size parameters. I doubt the
defaults are wrong on a system this old, but you never know. The
KCS interface uses two 8-bit ports, and the pnp range is ca0-ca7,
so that should give you a range to work in.
Beyond that, I really don't know. I do have reports of the driver
working with older Intel systems, so I think it should work ok. And
unless you need IMB emulation, there is no need to load that part of the
driver.
