Your average close-to-release distrib/notes/FOO update.

This time:
- update hardware list, reorganize it more logically
- gets most of the bsd.rd description and instructions on par with other
  arches
- document hov to create a boot tape, and how to boot via s-records
- tries to be more verbose about board setup

This is still way too concise. If you write english better than me (trivial)
and know mvme68k a bit, you're welcome to help fill the blanks.

At least this is better than the existing instructions, and deraadt@ agrees.

-MVME162:
+Before installing OpenBSD on your machine, you will want to check your
+machine's NVRAM settings.
+
+The defaults settings are usually suitable for OpenBSD; make sure the
+environment is configured in BUG mode. You can check and change this with
+the ENV command.
+
+You wil need to check that the ethernet address is correct as well, with
+the LSAD command.
 
+Some models also require specific preparation:
+MVME147:
+	Make sure the word at memory FFFE0764 is correct. Its value should
+	be zero if you don't have any VMEBus memory cards. You can change
+	its value with the MM command.
+
+MVME162:
 	Be sure to use the SET command to set the date before trying
 	to use the ethernet support in the 162-Bug.

+If you plan to boot from the network, make sure your ENV settings match
+the following setup:
