SE/30 odd behavior

I have had to postpone further testing of my appletalk/ethertalk
bridge setup because my SE30 has developed some problems.

The symptoms:
The machine thinks that there is a floppy disk in the superdrive
constantly; it is always trying to read the (empty) drive,
then the "This disk cannot be read; Initialize? Eject?" dialog
box shows up, I click on "eject" and it starts trying to
read the nonexistent floppy again.

Thinking that some switch or optical sensor had gone awry, I
replaced the drive with another superdrive. Same behavior.
Both drives work fine when installed in a second machine.
Once, when I was rebooting, I noticed that even before loading
the HD driver the machine looks at the floppy first, then gives
up and proceeds to boot from the HD. So, what that tells me
is that this is no software issue. By the way, this behavior
started suddenly after a few hours of operation on Sunday and
has continued ever since.

So, what kind of failure (in the SE30 mainboard, I guess) could
possibly be causing this? Is there a "media changed" line that could
be picking up noise? I must say that drives have never
been my area of expertise; I just clean some of them ocasionally.

Regards,

carlos.
