If that information 143 is not available, use the information provided in your disk's manual. 144 Please note that the geometry printed at boot time is preferred. 145 146 IMPORTANT NOTE: due to a limitation in the disklabel(8) program, the 147 number of cylinders on the disk will be increased by 1 so that the initial 148 label can be placed on disk for editing. When the disklabel editor appears, 149 make absolutely certain you subtract 1 from the total number of cylinders, 150 and adjust the size of partition 'c' such that: 151 152 size = (sectors per track) * (tracks per cyl) * (total cylinders) 153 154 Note that the disklabel editor will be run twice; once to set the size of 155 partition 'c' and correct the geometry, and again so that you may correctly 156 edit the partition map. This is to work around the afore mentioned 157 limitation in disklabel(8).

So, we've given ourselves 224 # an `a' partition, which is the minimum needed to open the disk 225 # so that we can perform the DIOCWDLABEL ioctl. So, once the 226 # initial label is installed, we open the `a' partition so that 227 # we can fix up the number of cylinders and make the size of 228 # `c' come out to (ncyl * ntracks_per_cyl * nsec_per_track). 229 # After that's done, we re-open `c' and let the user actually 230 # edit the partition table.
