jonathan 9fe4d42638 Set otherwise-unused global variable `disksectors' to disklabel.d_secperunit. 
Change   fdisk -S to  emit disksectors as DLSIZE (for benefit of sysinst.)

ws 1cd9ec3c71 Separate master bootcode from fdisk. 1998-10-15 15:23:23 +00:00
ws ba2f852285 Completely zero out a partition table entry, 
if type, start and size are given as zero.
 1998-10-02 17:23:22 +00:00
ws d8881a6f9a Automagically initialize boot code and partition table if not yet valid. 
Don't touch the partition table on -i, if previously valid.

rvb db826b28d9 Dont report more than 1023 cylinders for DOS/BIOS because 
the code below will truncate to a 10 bit field.  This
can cause major problems later for DOS.

drochner c0f9ff25e7 Use the new NetBSD partition ID for first time setup of an MBR. 1998-02-25 14:19:12 +00:00
drochner 43e4e2726a Add new NetBSD partition ID. 
Update information about partition types - add missing types, insert
"reserved" for IDs which are marked as "officially reserved" in other
lists.
Sources of information:
-"How it Works -- Partition Tables" by Hale Landis <hlandis@ibm.net>
-Ralph Brown's interrupt list

ghudson 70698891e2 When estimating the number of cylinders in the BIOS geometry, use the 
total number of sectors as reported by disklabel.d_secperunit rather
than multiplying out the disklabel geometry, which is less accurate.

mikel b545bd186c Don't print "DOS partition initialized" if -S set; from Nathan 
Williams in PR bin/4893.

enami 24ec6663fe Add missing cast. This is a minimum fix to avoid overflow which causes 
core dumps with some disk geometry.

lukem 216ef04613 switch to using opendisk(3) from libutil 1997-09-25 05:08:28 +00:00
lukem 6e61b15d9c * support ``short'' names of disks (e.g, ``sd0'') instead of requiring 
the full name (e.g, ``/dev/rsd0d'') a la disklabel(8) (where the code
  was effectively lifted from ;-)
* prefix hexadecimal numbers in output with '0x'

phil 5388cd2717 Don't print some things if -f flag given. 1997-09-11 22:53:00 +00:00
phil 2d074efe44 -- add -b flag for setting fdisk's idea of BIOS geometry from command line 
-- cleanup so WARNS=1 works
-- man page updated to reality.

phil 1b063875bf Upgrade for non-interactive use. Interactive use is nearly unchanged. 
-i no longer implies -u, -i now does not use the entire first track
because some BIOSes refuse to boot from a partition in the first track.
-s renamed to -S, new -s for non-interactive setting of a partition's
id, offset and size.  Updated documentation to match.
 1997-08-11 23:31:41 +00:00
phil 1145b74178 Add code for a -s flag where the output is a series of VAL=xyz lines 
so /bin/sh can "eval `fdisk -s`" and get variables defined with the
fdisk information.

perry c94b6b4f09 Add a whole lot of MBR partition types, derived from a couple of sources 
including Linux.
Is there a master list of this somewhere?

ghudson 9b746f76a4 Add code to look at the existing partition entries to deduce the 
translated geometry of the disk.  This code will only change the
disk geometry if it can find a geometry which is consistent with
all partition entries, so it's very conservative about choosing
a new disk geometry.  Under some circumstances, it will choose a
number of cylinders which is a little lower than it needs to be,
but this code is enough so that you can create new partitions
with the correct physical addresses.

The right solution to this problem is to have the boot loader
communicate the BIOS geometry of each disk to the kernel, in a
manner similar to the symbol table, and then provide a kernel
interface to get at that information.  I'm unfortunately not
really qualified to make such a change, and I want something
that works better than the status quo.
