Thanks for your feedback, Erik! I do have a question below...

The kernel I am using is the kernel from the DVD ISO as it is downloaded from freebsd.org. How do I determine what modules have been enabled and disabled in that kernel? I am under the assumption that NFS is compiled into that kernel. We can install 8.2-RELEASE with this kernel in VMs, but not bare metal. Is there an explanation as to why an NFS enabled kernel would work inside a VM, but fail on bare metal? --=20 Take care Rick Miller
