Title: "3C505 & 3C605 initialization error n" messages

The following are error messages that could be seen at driver
initialization time for EtherLink Plus (AKA 3C505, IE3) or TokenLink
Plus (AKA 3C605, IR6).

.br;"3C505 initialization error n"         or
.br;"3C605 initialization error n"

where n is a number (1-6) with the following meaning:

1  No response from the adapter after the host PC requested it to
perform Reset/Self Test.  I just discovered there is a bug in
the driver code.  You should get this message if you specify the
board's address incorrectly but, instead, the driver just
hangs.  I am filing a bug report.  You can still see this
message; most likely from a bad adapter.

2  Failed sending an adapter command block (PCB) from the host PC
to the adapter.

3  Failed getting an adapter response block (PCB) from the adapter
to the host PC using programmed I/O.  This is used to get the
self test results.

4  Failed getting an adapter response block (PCB) from the adapter
to the host PC using default I/O.  The default I/O method is
DMA on a PC, so this may imply a problem with DMA.

5  Error configuring adapter.  Error status was returned in
response to configuring the adapter's memory.

6  The adapter's Self Test function detected an error on the
adapter.

Most of these errors simply imply the board is broken or configured
wrong.  Error 6 is a pretty sure bet for a bad board.  Error 1 would be
a good indication of an address mismatch between the jumpers and
CONFIG.SYS line, but it doesn't work right so a wrong address causes a
hang.  If you do see error 1 on the current drivers, it is probably a
bad adapter board or PC.
