140
141You will need to provide some information about your disk's geometry.
142Geometry info for SCSI disks was printed at boot time.  If that information
143is not available, use the information provided in your disk's manual.
144Please note that the geometry printed at boot time is preferred.
145
146IMPORTANT NOTE: due to a limitation in the disklabel(8) program, the
147number of cylinders on the disk will be increased by 1 so that the initial
148label can be placed on disk for editing.  When the disklabel editor appears,
149make absolutely certain you subtract 1 from the total number of cylinders,
150and adjust the size of partition 'c' such that:
151
152	size = (sectors per track) * (tracks per cyl) * (total cylinders)
153
154Note that the disklabel editor will be run twice; once to set the size of
155partition 'c' and correct the geometry, and again so that you may correctly
156edit the partition map.  This is to work around the afore mentioned
157limitation in disklabel(8).  Apologies offered in advance.

482This program is designed to help you install NetBSD on your system in a
483simple and rational way.  You'll be asked several questions, and it would
484probably be useful to have your disk's hardware manual, the installation
485notes, and a calculator handy.
486
487In particular, you will need to know some reasonably detailed
488information about your disk's geometry.  This program can determine
489some limited information about certain specific types of HP-IB disks.
490If you have SCSI disks, however, prior knowledge of disk geometry
491is absolutely essential.  The kernel will attempt to display geometry
492information for SCSI disks during boot, if possible.  If you did not
493make it note of it before, you may wish to reboot and jot down your
494disk's geometry before proceeding.
495
496As with anything which modifies your hard disk's contents, this
497program can cause SIGNIFICANT data loss, and you are advised
498to make sure your hard drive is backed up before beginning the
499installation process.
500
501Default answers are displyed in brackets after the questions.
502You can hit Control-C at any time to quit, but if you do so at a
503prompt, you may have to hit return.  Also, quitting in the middle of
504installation may leave your system in an inconsistent state.
