the START UNIT command before testing whether the device is ready.
Maybe it should be done even earlier, i'm not 100 % sure.
Again, CD changers will most likely benefit from it.
While i was at it, also made the debugging case a little more verbose
about why the cdopen() yielded an ENXIO. (Only in effect when
SCSIDEBUG is specified.)
Should eventually also go into 2.2.
error code with ASC/ASCQ 4/1 (``Logical unit is in the process of
becoming ready'') non-fatal. Retry the operation until it will
eventually either yield a real error condition, or finally succeed.
Devices like CD changers or tape drives with a freshly inserted
cartridge should benefit from this.
Should go into 2.2 after some testing in -current. I'd like to see
this in the release if possible.
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.

the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

with another one of the same size.
