This is more likely a PCI probe problem, than a NCR problem. Could you please be more specific about the failure mode ? Is there any PCI chip found at all ?

The Compaq chip sets have been making trouble (at probe time, they seem to work fine, once the system is running). I had to add quite some special code to support earlier versions, but found it would not work with a more recent one ... There was one report of a problem with a ALI based Pentium. All these problems will be solved by using the PCI probe code from FreeBSD-current (/sys/i386/isa/pcibus.c). If you can recompile your kernel with them, then let me know, whether this sooves your problem. If you have both 2.0.5 and 2.1 on the same system, then you might be able to write a new kernel on the 2.1 root partition frim 2.0.5. In this case, I might be able to send you a kernel with the new boot probe for you to try ...
