no it is not a garbage.. It's just zero filled disk. Geometry
detection process uses info from preexisting partition table?
And the zero fill included the MBR making it garbage.
so we must prepare MBR with 3rd party tools before OpenBSD installation?
No, fdisk -i will put the right values in. This will be done by the
install script if you choose to use the whole disk for OpenBSD. If you
do not want to use the whole disk, you can use any fdisk tool
(including the OpenBSD one) to setup your disk.
result of fdisk -i is the same:
Disk: sd0 geometry: 78753/2/911 [143638992 Sectors]
(which is, I suspect, just physical scsi disk real geometry)
I can accept any geometry, but anyway, why fdisk reports _diffent_
values on install and after install on working system ? because of some
differences in /bsd.rd and /bsd ?
