cf49270ac3 Enter complier upgrade mode again. We need to cut 169 bytes from this: 
Remove some printf() calls, reduce size of buffers, and abbreviate
	some strings.

Hopefully the boot people will fix this spamage after the cut over to
Gcc 2.95.2 as the system compiler.

73de3d0ff7 Turn on the -fforce-addr and -fschedule-insns optimizations. Adding 
either one gives us an additional 32 bytes of additional space available
when using EGCS 1.1.2.  With GCC 2.95.2 -fforce-addr gives us 12 more bytes,
and adding -fschedule-insns gives us an additional 4 bytes.

df5ee53868 Remove the string ">>> FreeBSD/i386 BOOT". I need to reduce the size of 
boot2 by 16 bytes.  I expect this to be temperary until the boot2 authors
can do the proper fix.

9859e703f6 Make <DEL> an alternative rubout character for command input; many

5d3d992565 Fill in the bi_bios_dev field in the bootinfo struct; the loader doesn't 
guess this value well in anything other than the simplest of situations.

c03b24b2d8 Damn, I thought I had committed this already, but it seems not. 
Move the relocated boot1 and arg transfer space from 0x600/0x800 to
0x700/0x900.  In theory this should make no difference, apart from the fact
that Buslogic controllers happen to use a few bytes at 0x600 for some sort
of scratch space for it's int 0x13 hook (!!!), causing the machine to crash
badly when the boot2 code makes it's callbacks into boot1 for disk IO.

7ac90f7d65 Drop the familiar 'text=xxxx data=xxxx bss=xxxx ...' display while 
loading.  This eliminates noise when loading boot/loader; and when
loading a kernel, they generally flash by too fast to be
intelligible anyway.

9888bdcd29 boot1: Eliminate EDD detection and optional use of disk packet 
interface.  Do some general consistency fixes and space optimizations.
Use of some freed-up space to defend against possible BIOS misfeatures.

boot2: Revise disk read interface to provide for boot1 changes.  Free
up space for this.

93d51dcaf9 Treat all options as toggles (ie. -c -c is the same no -c). Since 
the boot.config settings are persistent, this seems to provide a
useful override capability, and should break only on broken
boot.config's.

Output a cosmetic newline if booting with no input.

7fa25d805a biosboot compatibility fix: 
Read boot.help before parsing boot.config.  We were parsing
boot.config first, which could result in boot.help being read
from a different location (or not found), which would probably
just cause surprise, without being useful.
