  This would be the 3COM network card.  SRM is only going to know about 
"real" DEC Tulip boards for network booting.

  This should be the DQA0 CDROM device.  I suspect it may have to be a 
CDROM device that could present 512 byte sectors.  I don't remember if I 
ever tried booting with the CDROM (now a DVD drive) on my PC164, so I 
don't know if the SRM is smart enough to deal with the 2048 byte blocks.

  Correct.

  There's some mention about this in the source (but not much more), and 
even the ES40 does that.  I do have problems attempting to use the DVD 
drive on the ES40 under NetBSD (gets ata timeouts), but the DVD drive in 
my PC164 works quite well.

  The SRM shows an optical device, and it should show up on the 'show 
device' command.  It also should show as cd0: during autoconfigure.
