I followed the thread about changing the kernel parameter 'nbuf' with 
some interest, and probably incomplete understanding.  I decided to
alter the number of buffers just to see what sort of difference it would
make.  I used the bsd() sdmach nbuf=NNN command, rather than hack the
kernel.  I understood that the command above would have to be re-entered
at every reboot, while the purpose of the hack was to make the change
permanent.  However, I rebooted the machine to undo the change in
nbuf and to my suprise it came back up with the altered number of buffers.

I mention this 1) to find out more about this behavior, and 2) to say that
doing it this way seems a lot easier than hacking the kernel.

Any comments, info?

Thank you very much and have a good day.
