  So this is an actual *card* that provides a PS/2 mouse connector,
and not just a connector from the motherboard's "PS/2" socket/pins?
  [The mystery, then, is why you're getting a "keyboard error"
message.  Does it go away if you put the mouse back on serial 1?]

  PS/2 mice and keyboards use similar voltage levels, so *in general*
no permanent harm should be done if they're plugged into one
another's sockets.  The machine just won't operate correctly hooked
up that way.
  But I'm a bit concerned by your reference to moving the mouse from
"serial 1" to PS/2.  I know that you can get adapters that will allow
a serial mouse to be physically connected to a PS/2 port, but my
understanding is that these should only be used with mice designed to
handle that.  [My hunch is that the PS/2 port will supply less power
than a serial port, and that may not be enough for some mice to
function.]

  I'm cc'ing this back to the list in case someone else has an idea.
