3157adc8af Removed now-unused #includes of <machine/cpu.h>. They were for bootverbose
being declared in the wrong place.

33309c7fc0 More b_flags fixes. 1996-03-02 01:49:51 +00:00

f5d1e6dae6 Fix a bug that b_flags was getting unnecessarily modified by
the slice code.  The effect up to now has been insignficant, but
improved buffer allocation code will break with this problem.

215b0e62d5 Don't clip d_ncylinders to value used by partitions. 1995-08-23 11:43:45 +00:00

b8ef36f62e Properly initialize the d_ncylinders field to the maximum number of
cylinders.

4977228d33 Make the "information" slice printfs if(bootverbose).
Fix the message about Ontrack.

ee1cbe818e When past cyl 1024 it's ok if CHS is (0xff,0xff,0xff).
It's actually recommended it seems...

f4d1e3d1e7 Remove the slice for the first 63 sectors for the OnTrack case, it's useless
and nobody care about it anyway.

0e175c5ef0 Added support for disks which "OnTrack Disk Manager" has munged.
I suggest you do all partitioning using the OnTrack SW, to avoid
confusing it.

a7d783dddb Add more compatibility cruft:
- ignore the partition table if it is identical with the bogus one in
  /usr/src/sys/i386/boot/biosboot/start.S.  Honoring the bogus size
  field was fatal.  The error is detected but other compatibilty
  cruft weakens the error handling too much for this case.
- weaken the partition entry checking to allow the following treatments
  of C/H/S addresses when C should be >= 1024:
    (1) allow C = 1023, H = max, S = max.
    (2) allow C to be correct modulo 1024.
  Other compatibilty cruft weakens the error handling to allow all
  C/H/S addresses, but there too many errors were reported.

Improve error messages:
- print C/H/S addresses if relevant.
- distinguish primary partition table from extended partition tables.
- don't use diskerr() except for i/o errors.

fe7172b1a6 Fix support for extended partitions (forgot to release the buffer). 1995-03-15 16:25:08 +00:00

7262c5ee2c Support extended DOSpartitions.
Accept even suspicious partitions.

Moved most handling of the compatibility slice to dsopen().

Report i/o errors.

30ca037de1 Use dsname() to get consistent names. 1995-02-22 22:46:48 +00:00

22544eb7a0 Don't generate any errors here other than EIO. An invalid partition
table is not an error, it just causes a smaller slice table.

7a867ed547 Add compatibility cruft.
Slice 0 is now for the first BSD slice.  The first BSD slice is
the first DOSpartition with id 0xa5 or the whole disk if their
are no DOSpartitions (except the latter is not yet implemented).
Existing partitions on it work the same as in 2.0 except the
'd' partition is no longer special and partitions are relative
to the skice.

Slice 1 is now for the whole disk and gets a read-only label
describing the disk.  Previously, slice 0 was for the whole disk
and there was no label on it.

Slices 2-31 are for DOSpartitions.  Slice 0 is an alias for one
of these if there is a BSD slice.  Previously, slices 1-31 were
for DOSpartitions.

diskslice_machdep.c:
Expand whole disk slice to include all DOSpartitions.  More work
is required for >1024 cylinders and to rewrite the label iff the
driver is unsure about the geometry.

subr_diskslice.c:
New function dsisopen() to help handle media changes.

0300a965c8 diskslice_machdep.c implements reading and checking of DOS slice tables.
It will eventually replace readMBR.c.
