All right, I must admit that I'm a little bit hacked off here.  You made a
fair bit of noise on the FreeBSD bugs list about your Compaq Deskpro XL and
its SCSI controller, which you said:

In 2.1.1 of the current Handbook, "Disk Controllers", last updated
2-Mar-1999, there is a list of devices known to be supported.  This

        NCR5380/NCR53400 (``ProAudio Spectrum'') SCSI controller. 

However, for the current FreeBSD release (3.1) this is incorrect.

But *now* you say you have an AMD chip!  As it turns out, there *is* a
FreeBSD/CAM driver for the AMD 53c974, but it just hasn't been checked in
yet.  (Justin is still reviewing it.)  It was written by a guy at Tekram.
(they should be commended for their support for free software..)

Anyway, before you complain, you should make sure that you're complaining
about the right thing.  If you had said that you were having trouble with
getting an AMD chip working, you would have gotten the driver in short
