Subject: datasheets for the CMD640b and RZ1000 PCI IDE chips

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
