The current ncr driver supports most every NCR 53c8xx variant. Gerard's driver only supports newer NCR chips, because of some difference in the programming interface. (I think he doesn't want to support the older boards, although you can ask him what his reasons are.) Here's a comment from the README file: * Copyright (C) 1999 Gerard Roudier <groudier@club-internet.fr> * * This driver also supports the following Symbios/LSI PCI-SCSI chips: * 53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895. * * but does not support earlier chips as the following ones: * 53C810, 53C815, 53C825. In any case, my guess is that when Gerard's driver goes into the tree, we will not be getting rid of the current ncr driver. We'll either make it optional, and make the current NCR driver the default, or adjust the probe routines so that when the sym driver is present, the ncr driver will only attach to the 810, 815 and 825.
