325bde0fb7 Remove metion of the 'magic options.' Apparently PXE doesn't require the
special options on 0.99c (it mumbles something about 'PXE server not found'
but works anyway), and it won't work at all with PXE 2.0.

773065b3b8 Switch to using the .code16 as(1) directive and using 16-bit assembly
code instead of using 32-bit code and having to just "know" that it's
really 16-bit instructions when things run.  This also allows the code
to use fewer macros and more actual assembly statements, which eases
maintenance.  Unfortunately, due to as(1) brokenness, we still use m4
macros for all 16-bit addresses, and all short jumps (i.e., 8-bit
relative addresses in the jump instruction) must be wrapped in .code32
directives to avoid useless bloat by as(1).  This also fixes a few
problems that were preventing boot0 from compiling with the latest
and greatest version of as(1).

d08ae64b1d Bring support in for Intel Wired for Management 1.1 (PXE 0.99 and
below).  This did not work previously because interrupts were
disabled when PXE calls were being made, and they must be enabled.
This should also allow us to be compliant with all newer PXE rom's
from Intel.

For PXE 0.99, this has been tested using the Intel N440BX motherboard
and I am confident it will work on the Intel L440GX motherboard.

Lots of help/information from: jhb, peter

I would like to thank Michael Johnston <michael.johnston@intel.com>,
Mike Henry <mike.henry@intel.com>, and all the other PXE developers
at Intel for their help, and information in helping solve this
problem.

36273c5d79 Don't disable interrupts when calling a vm86 mode interrupt or routine
from user mode.  Don't disable interrupts when returning from vm86 mode
to user mode either.  Now, we only disable interrupts before calling a
hardware interrupt handler, which is the only time we _should_ be
disabling interrupts.

Because of this, err, feature, any routine that one called in vm86 mode
had to re-enable interrupts by setting the interrupt flag or interrupts
would remain disabled even after the routine returned.  For example, I
have a simple debugging routine that uses a vm86 mode function to dump
any arbitrary memory word that I use to read the BIOS timer or any other
memory location.  This function does 1 load instruction from memory and
then returns.  Since it didn't re-enable interrupts, the first time I
called it to read the BIOS timer, it disabled interrupts.   This also
affected the PXE bootstrap as it needs interrupts enabled while it is
processing.  This patch fixes both of those situations so that those
functions do not worry about having to enable interrupts.  Hardware
interrupt handlers worked fine with the old code because they always
enable interrupts as part of their routine.

If you have any problems with the loader after this commit, please
let me know.  I'd like to MFC it in a week or two since PXE support
needs it.

48a0c4ea04 Mega i386 loader commit.
- Don't hard code 0x10000 as the entry point for the loader.  Instead add
  src/sys/boot/i386/Makefile.inc which defines a make variable with the
  entry point for the loader.  Move the loader's entry point up to
  0x20000, which makes PXE happy.
- Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE,
  instead use m4 to achieve this.  Also, add a BTXLDR_VERBOSE knob in the
  btxldr Makefile to turn this option on.
- Redo parts of cdldr's Makefile so that it now builds and installs cdboot
  instead of having i386/loader/Makefile do that.  Also, add in some more
  variables to make the pxeldr Makefile almost identical and thus to ease
  maintainability.
- Teach cdldr about the a.out format.  Cdldr now parsers the a.out header
  of the loader binary and relocates it based on that.  The entry point of
  the loader no longer has to be hardcoded into cdldr.  Also, the boot
  info table from mkisofs is no longer required to get a useful cdboot.
- Update the lsdev function for BIOS disks to parse other file systems
  (such as DOS FAT) that we currently support.  This is still buggy as
  it assumes that a floppy with a DOS boot sector actually has a MBR and
  parses it as such.  I'll be fixing this in the future.
- The biggie:  Add in support for booting off of PXE-enabled network
  adapters.  Currently, we use the TFTP API provided by the PXE BIOS.
  Eventually we will switch to using the low-level NIC driver thus
  allowing both TFTP and NFS to be used, but for now it's just TFTP.
