5ffa52e68e Add workaround to allow the FreeBSD boot block to work on
Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
on having a short jump and nop as the first instructions in the
boot sector code. The prevailing theory is that the BIOS is doing
some sort of boot sector virus detection and refusing to run any
boot block that doesn't start with the same instruction sequence as
MS-DOG boot sector code. If this is the case, it would be nice if it
actually printed an error message to this effect instead of just
saying 'FAILED.'

This workaround has no effect on the boot sector code other than to
increase its size by three bytes.

406115eeb3 These are a selection of small problems and annoyances with the netboot
code. Apart from the first one, none really affect typical configurations
but are nevertheless unnecessary limitations. We use netbooted PCs as
student X-terminals and all of the below fixes have been useful. Apologies
for including them all in one PR, but some are just too silly or trivial
to send on their own!

a)     Newer SMC cards have hardware addresses starting with 00:E0.
      Netboot compares the MAC address with 00:00:C0 to determine
      if it is a WD/SMC card, so it fails to detect these.

b)     Netboot is unable to boot kzipped kernels, as it assumes that
      the kernel load address is 0x100000.

c)     Users can abort the booting process and enter arbitrary network
      addresses, or boot from a floppy disk. This can be a problem when
      netbooted machines are used in a student environment.

d)     It is not possible to set all options via bootp. For example there
      is no way to remotely force a client to boot from disk. With both
      SECURE_BOOT(patch below) and NO_TFTP defined, short of unplugging
      the eprom there is no way at all to get the client to boot locally.
      A generic solution is to allow complete netboot commands to be sent
      using bootp lines such as:
	      :T132="diskboot":
e)     The last character of netboot command names is not checked. You
      can type 'iz 10.0.0.1' and it will be interpreted as 'ip'. This
      is only important if you try to add a new command which is the
      same as an existing one except for the last character.

f)     We have a configuration where multiple servers are willing to serve
      a diskless client. The tftp config file, or the bootptab entry on
      each server must specify the root and swap filesystems as 'ip:/fs'
      even though 'ip' will usually be the responding server's IP address.
      It would be nice if netboot could automatically prepend the server's
      IP address to an entry specified as just '/fs', so that multiple
      servers can use the same tftp or bootp configuration files. Admittedly
      this is hardly a major problem!

c81672091f (Part #2, after the Internet link broke totally yesterday.)
This is the long-threatened ISO 9660 CD-ROM bootstrap code.

This work has been sponsored by Plutotech International, Inc (who paid
the initial work), and interface business GmbH (where i did most of
the work).  A big thanks also goes to Bruce Evans, for his continuing
help and answering my stupid questions.

The code is basically functioning, with the following caveats:

. Rock Ridge attributes are not yet supported.
. Only SCSI CD-ROMs are supported, since i fail to see any possibility
  to determine the drive type using BIOS functions.  (Even for hard disks,
  this determination is done by a big hack only.)
. El Torito specifies a lot of crap and useless misfeatures, but crucial
  things like the ability to figure out the CD TOC have been ``forgotten''.
  Thus, if you wanna boot a multisession CD, you need to know at which CD
  block your session starts, and need to speciffy it using the @ clause.

. None of the CD-ROM controllers i've seen so far implements the full
  El Torito specification at all.  Adaptec is probably the closest, but
  they miss on non-emulation booting (which would be the most logical
  choice for us).  Thus, the current code bloats the 7.5 KB boot code
  up to 1.44 MB, in order to fake a `floppy' image.

  If you wanna use it, specify this file as the boot image on the
  command-line of the mksiosfs command (option -b).

  Caveat emptor: some versions of the Adaptec BIOS might even fail to
  access the CD-ROM at all, using the BIOS functions.  I think i've
  notice this for ver 1.26, the code has been tested with ver 1.23.

The boot string is as follows:

        [@sess-start] [filename] [-flags]

sess-start      Extend # where the last session starts, measured in
                CD-ROM blocks.

filename        As usual, but the input is case-insensitive by now
                (since we  don't grok RR anyway).

flags           As usual, but -C (use CDROM root f/s) is default, so
                specifying -C will decactivate this option (which is
                probably not what you want :).

A lot of cleanup work is probably required, and some of the files
could/should be merged back to biosboot, perhaps made conditional on
some #ifdef.  The malloc implementation that comes with cdboot might
also be useful for kzipboot.  (I needed a malloc() since the root dir
ain't fixed in size on a CD.)

I've been testing all this with a 2.2-STABLE as the base for biosboot.
I don't expect too many surprises, although i know the biosboot stuff
has been changed a lot in -current lately.  I'm sure Bruce will
comment on all this here anyway. :-)

Reduced the command line buffer size yet again from 4096 to 1024.  It is
oversized to defend against overrun in gets(), but data space is starting
to run out so the buffer size can't be as grossly oversized as before.

89c2812e94 This should have been committed with the changes to boot.c yesterday.
- Added support for "dual" internal/serial consoles (-D flag).  If -D is set,
  then all i/o from the boot blocks is to and from both the internal console
  and the serial console.  -D has no effect on the kernel (-h decides the
  kernel serial console as usual).  -D should normally be set in /boot.config.
- Get help messages from /boot.help.  You should copy boot.help from the
  biosboot directory to the root directory on the boot drive when you
  install new boot blocks.
- New, less invasive keyboard probe.  Enable keyboard probe dynamically (-P
  flag).  Should probably never be used (use -h instead).
- Fixed/improved initialization from boot.config.  It didn't interact correctly
  with the NAMEBLOCK option, and the initialization of the drive/unit/partition
  didn't stick when a non-default kernel name was entered.
- Don't reset or forget the default drive/unit/... or kernel name so often.
- Set the default kernel name to something unbootable after `?'.
- Display the defaults better.
- Removed PROBE_KEYBOARD_LOCK option (use -h instead).,
- Removed BOOT_FORCE_COMCONSOLE option (use device flag 0x20 instead).
- Removed -a (RB_HALT) flag.  This flag is only used for reboots.
