Actually, I'm using the same keyboard, mouse and monitor with four 
computers, running through a KVM switch.  Two of the computers have 
never displayed that message, one displays it quite often, and one very 
seldom.  The computers that never display that error are an old Digital 
and an OptiPlex.  The two that do are both OptiPlex's.  (To simplify the 
initial question I just compared the two OptiPlex's on the opposite end 
of the spectrum.)

Typing all that out - I suppose it could be the KVM switch?  But then 
how about the memory boards?

One other detail.  At the time I bought the OptiPlex, the used shop I 
got it at had several OptiPlex models in stock, and some of them were 
labeled as sometimes not recognizing their floppy drives.  The one I 
bought carried no such warning, but it was from the same batch.  A 
glitch in the OptiPlex GX-110 model perhaps?  (But what about the lost 
memory boards?.....)
