4238458ba2 Fix the local macro: isvisible().
- The space char (0x20) IS a visible char :-)

b827a63aa6 Fix the function CD(): "Clear to the end of the screen".
- When the video BIOS is called to clear the region (x, y)-(79, 24)
  (by scrolling), the slashed region in Fig.1 is cleared.  CD() is
  supposed to clear the region shown in Fig.2.

6c8e596705 This is white-space only change. No functional difference.
- Be consistent about placing spaces around keywords and
  operators; don't mix statements like "if(A==B)" and "if (X == Y)",
  "return(0)" and "return (-1)", "P=10" and "Q = 0", etc.

- Consitently indent lines. It's not good to indent by 8 columns
  in one part of the file, and by 4 columns in the other part.

4ae4202e70 Cleanup warnings. Most of these are signed/unsigned warnings, as well as
some added const's.

e423230b0d Fix a potential sign extension bug on 8-bit chars.
Outputting a backspace isn't supposed to be destructive..  It isn't on
most terminals, nor on the standard bios output (vs. TERM_EMU mode)

cf9443f92b Add simple terminal emulator, compatible with cons25. Currently supported
capabilities are: AF, AB, cm, ho, me, cd. The code is hidden behind
-DTERM_EMU - should it cause any problems, you can remove this define
to get back the old behaviour.

You'll find some examples how to use it in src/share/examples/bootforth.

dc8be6a8f5 - Add a new command 'lsdev' to list devices which might be likely to host
filesystems.
 - New 'help' command and data in the help.* files (not yet installed),
   provides topic and subtopic help, indexes, etc.
 - Don't crash if the user tries to set an invalid console.  Be helpful
   instead.
 - Expand tabs (badly) on the i386 video console.
 - Some minor cosmetic changes.

8879e57b3e Simplify the "is a character ready" test, so that we don't return a false
negative for keypresses with zero ascii values.  This is in line with the
comconsole test, rather than being more ambitious.

7d9cbdec8f Only call vidc_init() once (unless forced).
Cosmetic change to the init-time character eater (like, make it increment
the index counter - if there's a problem, it would sit there in an infinite
loop instead of only running 10 times).

6b15efd961 aout_freebsd.c
Use bd_getdev() to work out a dev_t for the root device.
	Allow $rootdev to override $currdev as the root device.

biosdisk.c
	Save the slice table and disklabel when opening a disk.
	Add bd_getdev(), which attempts to return a dev_t corresponding
	to a given device.  Cases which it still doesn't get right:
	 - The inevitable da-when-wd-also-exists
	 - Disks with no slice table (the slice number is not set correctly)
	The first is difficult to get right, the second will be
	fixed in an upcoming commit.

comconsole.c
vidconsole.c
	getchar() should return an 8-bit value; some BIOSsen pack extra
	information in %eax.

libi386.h
	Remove some stale prototypes, add new ones.

948486abe3 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.

c2f9d95de5 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.
