I think it is NO_GEOM, but I am not sure, grep'ing for NO_GEOM does not come up with anything though, but give it a try.

GEOM gets whole disk geometry for slice (instead of slice geometry)
I have disk shared between FreeBSD and M$ Win, two slices, and got incorrect disklabel with GEOM kernel. Namely cylinders and sectors/unit fields are from _whole_ disk, not from just requested slice. It invalidates previously correct 'c' BSD partition too, 'disklabel' outputs several warnings about it. I am not familiar with GEOM. In which place it senses cylinders and secs/unit? Does anyone saw the same problem too? Specific info attached below. Look at the wrong fields in disklabel. They even can't be corrected using 'disklabel -e'. -- fdisk: can't get disk parameters on /dev/ad0; supplying dummy ones *** Working on device /dev/ad0 *** parameters extracted from in-core disklabel are: cylinders=89355 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=89355 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 12514572 (6110 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 778/ head 254/ sector 63 The data for partition 2 is: sysid 7 (0x07),(OS/2 HPFS, NTFS, QNX-2 (16 bit) or Advanced UNIX) start 12514698, size 77545692 (37864 Meg), flag 0 beg: cyl 779/ head 1/ sector 1; end: cyl 1023/ head 254/ sector 63 The data for partition 3 is: UNUSED The data for partition 4 is: UNUSED -- # /dev/ad0s1c: type: ESDI disk: ad0s1 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 5606 ^^^ must be 778 (or 779?) sectors/unit: 90069840 ^^^ must be 12514572 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: #size offsetfstype [fsize bsize bps/cpg] a: 11900172 6144004.2BSD 2048 1638464 # (Cyl. 38*- 778*) b: 6144000 swap# (Cyl.0 - 38*) c: 125145720unused0 0 # (Cyl.0 - 778*) -- Andrey A.
