+ make Open_Disk sense the sector size by trying 512, 1024 and 2048
in this order. This makes the kernel note that
dscheck(cd1): bio_bcount 512 is not on a sector boundary (ssize 2048)
dscheck(cd1): bio_bcount 1024 is not on a sector boundary (ssize 2048)
if 2048 is the sector size. If this worries anyone: the message is from
/usr/src/sys/kern/subr_diskslice.c and shutups are to be placed there.
+ Have read_block and write_block use an additional parameter, the
sector size.
+ replace all barfout calls with return NULL, 0, __LINE__, etc.
Note that this does NOT emit diagnostics. More often than not,
you don't want library functions to scribble on stderr -- it may
not even be available. The right thing is to propagate the error
condition to upper management. The app should take care of errors.
+ use d1->sector_size instead of 512 in various places. I've left many
places untouched, especially those writing MBRs. I simply added
another arg hardcoded as 512. This is because I would not know what
I'm doing... I felt this approach would be reasonably backward
compatible and not introduce any new bugs in critical software.
Famous last words. Messing with MBRs might soon put me in the same
screwup meister category as, uh, never mind. :-)
+ bump the max no of disks from 20 to 32 (due to PR 24503).

Also, looking to the future, don't assume all the world is an i386 and all
its disk layout brain damage will be repeated by other platforms. So all
the diking out if we are an Alpha, becomes adding in if we are an i386.
`err()'). libdisk does! and additionally libdisk gets confused on Alpha
disks with foreign disklabels, throws up its hands and exits. This is
the cause of the "going no where without my init" install bug on the Alpha.
So now on the Alpha, rather than call err(), we print the error string and
continue processing.

present, this is limited to turning on the packet option if any of
disk slices begin above cylinder 1023. The effect of this change
should therefore be to automatically enable LBA support, as needed,
when installing FreeBSD.

- Axe all the 1024 cylinder checks as they are no longer relevant with the
fixed bootstrap.

A positive side effect is that non-root users may now use Disk_Names(),
for non-dangerous libh/disk.tcl testing.

Boy, I'm glad we're not using sup anymore. This update would have been

I've added an installation from optical disk drive facility.
This enables FreeBSD to be installed from an optical disk, which
may be formatted in "super floppy" style or sliced into MSDOS-FS
and UFS partitions.
Note: ncr.c should be reviewed by Stefan Esser <se@freebsd.org>
and cd.c by Joerg Wunsch <joerg@freebsd.org> before bringing this
into 2.2.

Add NOPIC=yes to Makefile to prevent any possibility of version mismatch
because of the potential grave consequences. (as suggested by phk)
Note that this is also on RELENG_2_1_0, since the sysinstall stuff is
hopefully going to remain in sync.
Remove bogus targets.
Allocate partition letters as follows:
lowest offset "flags & CHUNK_IS_ROOT" gets 'a',
lowest offset "subtype==FS_SWAP" gets 'b'
the rest is allocated in offset order from this sequence "defghab".
This will generally make sense.
Added rules to complain if more than one CHUNK_IS_ROOT or more than one
FS_SWAP per FreeBSD chunk.
Set CHUNK_IS_ROOT on the 'a' partition in Open_Disk.
Run Fixup_Names in Open_Disk.
Add mbr and bteasy17 to tst01

Still problems with writing labels, discussing with Bruce.
Extended slices doesn't get written yet.
Made an All_FreeBSD() function.
Added a cmd-line interface (lowest rank) to the tst01 program.
The tst01 program is harmless (worst it can do is coredump), but it
is instructive to run, you can see what the slice-code things of your
disk...
