You may of course try the Tekram driver. I'd like to know how well it works for you. (If you can run some benchmarks, I'd love to see the results.) There might be some minor problems with the Tekram driver, which I'd have to check in the sources. > On another note, will I be able to boot using the GENERIC kernel > against the Tekram controller? I am under the impression the base > driver will recognize the controller as an 825. No, the controller will be fully recognized, but many of the new features of the 53c875 will not be taken advantage of. (There is no support for loading the NCR code into the 875's 4KB SRAM, for example, or no negotiation of Ultra-SCSI transfer rates.) I wanted to clean up some of the code before the 20MHz speed is enabled, but was held back by some other (higher priority) tasks ... But I got reports of the "generic" NCR driver giving significantly better throughput anyway, and I guess I know why this is the case :) Regards, STefan
