CMD eventually faxed me the relevant pages for the CMD640B.
None of the 'information' available on the internet (yes, I read it before
I asked here) is of any use in actually fiddling the bits.
Yes, I looked at the Linux code for the CMD640B, and yes, I still needed the datasheet.
I don't have a motherboard with the RZ1000, does anyone?

how about looking at some linux code (I have a buggy CMD640 and linux
just recongnizes that and deals with it properly) or looking at
www.intel.com when I last visited there I saw they had some info on
the RZ1000 topic.

Unfortunately I dont have either...
I know intel has a web page on the rz1000 chips..
and the current linux source code detects CMD640b and rz1000
and handles it... you might want to check it out.
Wish i could be of more help... I'd gladly try and write a aha driver based
off of the linux one, but unfortunately... I dont have the cash to afford a
plan 9 Cd. :)
Now if we could only figure out how to get the aic-7850's working with the
linux aic7xxx driver. :)

Try Roedy Green, roedy@BIX.COM. He's done a lot of work on the problems
with these controllers, and will probably know of sources.

I saw an article in the local free computer paper that said both of
these chips have a number of bugs. A set of test programs and places for
discussion are listed as follows:

I've been unable to get the datasheets for these chips from the respective
manufacturers so I can turn off prefetch and, in the case of the CMD at least,
enable the second controller. If someone has either the datasheets and could
FAX them to me (+1 908 582 4417) or can supply the missing parts of the
following pseudo-code I'd be most grateful. Thanks.
if controller is one of the above
read some PCI config register
alter some bits
write the config register back
