Yup, you could do that, but the problem is finding out what the existing id codes are for. /etc/edttbl will print out the default known subdevice id's, but it doesn't look in the existing table. Filledt seems to be happy with type 11, and the entry on the boot menu says "HD135-B" or something similar. I guess disassembling filledt might reveal a table of all id's including the undocumented ones. It seems prtconf is able to see the number after the "HD" in the description field in /dgn/edt_data (which is what the boot programme displays), and prints that out as the size in megabytes. One other thing I should add is that I think I'm running with the new filledt which comes on the Core Upgrage Disk for 3.1 required for newer hardware such as the EPORTS and SCSI cards, though the filledt on the IDTOOLS disk also seems to know about type 11 drives. It's really sad that AT&T didn't see fit to publish all of this data in the service manual. I wonder where the "real" documentation is! I can understand not supporting third party drives (i.e. supporting only the 36Mb and 72Mb CDC Wren drives), but not documenting the system support software leaves even the service reps. out in the cold. The sevice manual I've seen doesn't even have the complete list of supported drive types! -- Greg A.
