cd37fe517b Return this file to its pre-spammed version. Thanks to some new compiler 
optimizations, we can go from 3 bytes free with the spammed version, to
279 bytes free with the full version.

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.

228ace6ebf aThis patch updates the BTX to emulate the BIOS function "Copy Extended 
Memory" called as function 0x87 of interrupt 0x15.  Since the Mylex RAID
adapter's BIOS used this function to access memory (actually PCI bus
space) beyond 16 MB, this patch also allows BTX to address all 4 Gig of
possible address space on i386+.  Since the loader does not have room for
4 MB of page tables, this was done by turning off paging.

Paging was turned off via a compile time setting which defaults to off.
To enable paging, simply define the make variable PAGING.

rnordier might want to clean this up later.

73332890ea Walk around the end of all the silly guessing of device types and unit 
numbers that we have been doing in the past, and read /etc/fstab off the
proposed root filesystem to determine the actual device name and vfs
type for the root filesystem.  These are then exported to the kernel
via the environment variable vfs.root.mountfrom.

This should resolve the problem raised in PR 12315, and incidentally
makes it easier to determine what geometry the BIOS is actually using
(by way of boot -v and dmesg).

3d8993c197 Modify the boot loader to recognize the -C flag and pass the RB_CDROM 
flag to the kernel to mount a CDROM as the root filesystem.  Alternatively,
the boot_cdrom env var can be set.

As Mike Smith noted, "-C is the "wrong" way to do this", but this is
an acceptable stopgap in lieu of a better way.
