3.12 We are running a 9x9 and trying upgrading to MPE/iX 6.0. The system will not boot to 6.0. It gives some kind of a firmware error. Has anyone else seen this error?

It may be that the firmware revision of the DDS is wrong.

The installation manual has a checklist item in which the operator is told to check the firmware revision level of the DDS drive, and provides instructions for doing so. The item concludes with a statement like "verify that the firmware version is 10.7". Naturally, anyone who's been in this business longer than about two weeks reads that as, "verify that the firmware version is 10.7 or later." It turns out that in this particular case, there is exactly one firmware revision that works, and it's the one given in the manual, not necessarily the latest firmware version.
