RD54 on an RQDX3?

Hi gang, I will buy an RD54 to replace that ornery RD53 on my MVII (recall we discussed the problem of the RD53 drive heads sticking a while back?) I just want to make sure that the RQDX3 EPROM versions on the controller will handle an RD54 drive. The version numbers are labeled as so: 285-E5 & 286-E5. I'm buying a spare RQDX3 controller board with these version numbers. The RQDX3 in the MVII have an older version # which I cannot recall at the moment. Already searched Sunsite and Tim's Micronotes. Nothing about the 285-E5 & 286-E5 numbers shows up. Back in October there was a ClassicCmp thread regarding handling of RX33 floppies. No comment about RD54's addressed. Thanks for the help.
