default for BINDIR. The default BINDIR of /usr/mdec can't be overridden
yet because libdisk still uses /usr/mdec and installing in /boot might
clobber the new boot blocks.
Don't install links to bootxx or xxboot.
Install boot1 and boot2 in 1 step.
Don't delete the boot.help source file on installing it when ${COPY} is
null.
install all those images at all (nor to install them under /usr/mdec), given
the high degree of customization this Makefile needs in order to get images
that are actually useful for some NIC.

be converted to fixed-sized integers when they are passed across the
binary interface to the kernel.
Didn't fix rotted bits (including not passing dosdev to the kernel and
serious out of dateness when initially committed).
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.
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!

They are atomic, but return in essence what is in the "time" variable.
gettime() is now a macro front for getmicrotime().
Various patches to use the two new functions instead of the various
hacks used in their absence.
Some puntuation and grammer patches from Bruce.
A couple of XXX comments.
- Remove reference to the obsolete options: BOOT_PROBE_KEYBOARD,
BOOT_PROBE_KEYBOARD_LOCK and BOOT_FORCE_COMCONSOLE.
- Add reference to BOOT_COMCONSOLE_SPEED.
- wrong name in .file statement.
- stale comment about CONSPEED.
- style bugs in comments.
- inconsistent defaulting of operand sizes (should never depend on default).
- inconsistent choosing between je and jz (should always use je).
so the filenames can be displayed and selected in full beauty. If RR
is present, the match is now case-sensitive, if RR is missing, the
match is case-insensitive (as it used to be before).
