Mark, Well, it (the crashing of floppies) is definitely a bug here on my
system. If it is a hardware bug, where do you suggest I look. Remember, this
same bug was present on my proto (single board) system. At the time I just
figured it was the software... At this point the only things the same are the
3.5" floppy (and the case).

Here are the current drivers I'm using:

  d0       #14   crc - 998410
  d1       #14   crc - BA83F3
  rb37c65  #4    crc - 1768E9
  rbf      #79   crc - F098AF

For hardware, I have 3.5" floppy and a 5" 80 track. I've disconnected the 80
and still get the same results. Just to refresh the debate, here is how to get
the bug:

 1. boot normally (I do it from the 3.5" and the process continues on /h0),
 2. attempt to access /d1 with the drive door open (dir /d1 "works" fine),
 3. after an error is generated, attempt to access /d0 (again, do something
    like dir /d0)--at this point I get an error!

With no disk in d1 the light on d0 flashes after 5 seconds, then the error is
reported after another 5 secs. If I remove the drive completely, the error is
reported right after the flash.

However, if you do an access to /d0 before all this (again, dir /d0 works)
everything appears to work okay.

BTW, I don't have a terminator on /d1. I put one on to test things, but then
the 3.5 became unaccessable, even for the boot process.
