ad6ddb7767 * Add old UFS compatibility code to alpha/boot1.
* Fix a raft of warnings, printf and otherwise.
* Allocate the correct amount in mod_searchmodule to prevent an overflow.
* Fix the makefiles so they work outside my home directory (oops).

bfe7e4f757 The BIOS can't perform a floppy operation where the destination crosses
a physical 64k boundary.  Allocate a bounce buffer for such a transaction.

7e33170a26 console.c
Allow the MI code to override the preferred console (eg. so that
	an RB_SERIAL flag from the i386 boot2 can override the default
	first active console)

isapnp.c
	Use the standard format for ISA PnP IDs.

pnp.c
	Allow trailing comments on lines, be less picky about line
	contents.

ls.c
	Cosmetic error message fix.

panic.c
	Print the right arguments.

0a0d8ce99a Make libstand movable.
This completes the basic work required to make the loader work with BTX. We
now have a third-stage bootstrap shared by the i386 and Alpha.

0523a3e013 - Improve debugging code.
- Make the "what do we do with a drunken disklabel" if-then-else-regardless
   tangle easier to read.
 - Don't count on the v86 structure being preserved between loop iterations,
   as it may be trampled eg. by the DEBUG call.

f0b5ddae6f Initial integration of the i386 bootloader and BTX.
- Discard large amounts of BIOS-related code in favour of the more compact
   BTX vm86 interface.
 - Build the loader module as ELF, although the resulting object is a.out,
   make gensetdefs 32/64-bit sensitive and use a single copy of it.
 - Throw away installboot, as it's no longer required.
 - Use direct bcopy operations in the i386_copy module, as BTX
   maps the first 16M of memory.  Check operations against the
   detected size of actual memory.

97d5b83076 Resynch with working sources before BTX integration.
- Use format-independant module allocator.
 - Conditionalise ISA PnP support.
 - Simplify PnP enumerator interface.
 - Improve module/object searching.
 - Add missing depend/install targets in BTX makefiles.
 - Pass the kernel environment and module data in extended bootinfo fields.
 - Add a pointer to the end of the kernel + modules in bootinfo.
 - Fix parsing of old-style kernel arguments.

63bfe0d0ad BTX (aka the boot extender) is an i386 kernel that hosts 32-bit
bootstrap programs, and provides page-level protection, hardware
interrupt reflection, a virtual-8086 mode interface to BIOS, etc.

2feae82d78 Bootstrap updates.
- Move some startup code from MD to MI sections
 - Add a 'copyout' and some copyout-related functions.  These will be
   obsoleted when BTX is available for the 386 and the kernel load
   area becomes directly addressable.
 - Add the ability load an arbitrary file as a module, associating
   and arbitrary type string with it.  This can be used eg. for loading
   splash-screen images etc.
 - Add KLD module dependancy infrastructure.  We know how to look for
   dependancies inside KLD modules, how to resolve these dependancies
   and what to do if things go wrong.  Only works for a.out at the
   moment, due to lack of an MI ELF loader.  Attach KLD module information
   to loaded modules as metadata, but don't pass it to the kernel (it
   can find it itself).
 - Load a.out KLD modules on a page boundary.  Only pad the a.out BSS
   for the kernel, as it may want to throw symbols away.  (We might want
   to do this for KLD modules too.)
 - Allow commands to be hidden from the '?' display, to avoid cluttering
   it with things like 'echo'.  Add 'echo'.
 - Bring the 'prompt' command into line with the parser syntax.
 - Fix the verbose 'ls'; it was using an uninitialised stack variable.
 - Add a '-v' flag to 'lsmod' to have it display module metadata as well
   (not terribly useful for the average user)
 - Support a 'module searchpath' for required modules.
 - The bootstrap file on i386 is now called 'loader' to permit the
   /boot directory to use that name.
 - Discard the old i386 pread() function, as it's replaced by
   arch_readin()

815f3686d0 Bootloader update.
- Implement a new copyin/readin interface for loading modules.
   This allows the module loaders to become MI, reducing code duplication.
 - Simplify the search for an image activator for the loaded kernel.
 - Use the common module management code for all module metadata.
 - Add an 'unload' command that throws everything away.
 - Move the a.out module loader to MI code, add support for a.out
   kld modules.

fc79e25bdf This is the new unified bootstrap, sometimes known previously as the
'three-stage' bootstrap.
There are a number of caveats with the code in its current state:
 - The i386 bootstrap only supports booting from a floppy.
 - The kernel and kld do not yet know how to deal with the extended
   information and module summary passed in.
 - PnP-based autodetection and demand loading of modules is not implemented.
 - i386 ELF kernel loading is not ready yet.
 - The i386 bootstrap is loaded via an ugly blockmap.

On the alpha, both net- and disk-booting (SRM console machines only) is
supported.  No blockmaps are used by this code.

Obtained from:	Parts from the NetBSD/i386 standalone bootstrap.
