The boot process for Level3 dies with a can't find module error. The coco3 bootfiles makefile does not match the info in Alan DeKok's doc nor some others I've seen. Changing the order in the makefile does not help and it is not clear what module is missing.

In addition to none of the Level3 floppies booting, the Drivewire bootfile_dw does not contain the rbdw.dr nor any of the x# descritors and ddx0.dd.
I will try to attach an image of a floppy boot failure.
AFAICS the module order seems to match what Alan wrote, except the descriptors should be moved out of the RBF block.
