AFAIK, the 53c876 is a dual channel version of the 53c875, i.e. much like the Adaptec 3940 implements two 2940 cards. According to the information I have on that device, I do expect it to work with an unmodified driver, but it may be necessary to add the PCI device ID. (It is more common to have a multi-function chip, that contains several devices that are also available seperately, use the original PCI IDs for each of its functions.) If the kernel does not accept the card, then I'll send you a patch for the NCR driver, based on VERBOSE boot messages supplied by you :) Regards, STefan
