The great suggestions I have received from some helpful people haven't made a difference the way I have applied them. I have set up a 30mb dos partition and the rest (82.8mb) for 386bsd. I have used diskedit to change offset 466 from 05 to a5 of the master boot record. Install detects the 386bsd partition and install runs just fine. When rebooted, the system goes into a panic loop saying it can't find the disk label. When I boot the fixit disk and do a disklabel wd0, I get warning messages: warning revolution/minute 0 boot block size 0 super block size 0 warning unused partition b: size 12168 offset 0 Disklabel wd0 > /tmp/dlwd0 generates the following configuration: # /dev/rwd0d: type: ESDI disk: ESDI/IDE label: 20MB - CP3010 flags: bytes/sector: 512 sectors/track: 17 tracks/cylinder: 15 sectors/cylinder: 255 cylinders: 762 rpm: 0 interleave: 0 trackskew: 0 cylinderskey: 0 headswitch: 0 #milliseconds track-to-track seek: 0 #milliseconds drivedata: 0 1 partitions: # size offset fstype [fsize bsize cpg] a: 172380 61455 unused 0 0 # (cyl.241-916) When I do disklabel -R -r wd0 /tmp/dlwd0 /usr/mdec/wdboot /usr/mdec/bootwd with the same config above, I get errors about partition a: extending past end of unit, as well as warnings that rpm=0, and bad interleave. When I slug in some values for these, and reduce the size on the a: partition from 172380 down to an arbitrary 100000, no errors are reported and it writes to the hd. When I get back into the dos disk editor, and look around cylinder 241, in sector 2, the 386bsd label appears with the value "20MB - CP3010", and yet, when booted, the label can't be found. Are there some obvious problems in the above configuration which install sets up? Any help would be appreciated :-) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Mike Whisenhunt |Internet: zmw@selu.edu |How to tell if your VMS System Manager/Postmaster |Phone : (504) 549-3643 |boss has used your Southeastern La.
