It's something to check, yes. It would be somewhat surprising if that

wouldn't be shocking :-)

I believe that this is only the case if the motherboard BIOS sets bit 6 
in the Control register to tell the device to respond to parity errors.  
Most of the "server" motherboards I've seen do.  None of the non-server 
motherboards that I've just looked at do....

The Status flag "should" still work whether the "parity error response" 
flag is set, or not...
