Yes, true in this case, but I think I still have issues respecting this
board and its BIOS -- subject for a separate thread perhaps.

I did not know about this command, which by the way is "showmount", so I
read its man page. Running "showmount -e SOL" on BDS returned the
directories exported from BDS, not those exported from SOL -- most
peculiar. I then got the bright idea to run "showmount -e
192.168.0.114", 114 being the IP address of the SOL box. This time the
command returned the directories exported from SOL. So what it going on?
By running ifconfig in both boxes I verified their IP addresses. I
checked the /etc/hosts file in both to verify that the right hostnames
were assigned to the right IP addresses. They were.
I paid particular attention to the BDS:/etc/hosts file, because I
assumed that the problem must reside there. Finally I noticed that the
local loopback alias was SOL, not BDS. The box now called BDS used to
be called SOL. When I changed the name I changed the name assigned to
the IP address of the new BDS (old SOL) but had neglected to change the
loopback alias. So I changed it, and BDS can now access the directories
exported from SOL.
I don't fully understand the loopback, but the fact that I had the
loopback alias wrong obviously explains why other things had not worked,
such as accessing html files from a browser using the alias rather than
