no, the kernel never loaded itself, we were never x86-savvy enough
to write assembler that would move the image up into extended
memory while in 16-bit mode.

The PXE bootloader seems to be in /sys/src/nix/w/pxeload.

Not yet, if you're willing to be a test subject head over to nix-dev
and we can work through the steps for you and add a document
explaining the process.

No. Compile an npxeload from /sys/src/nix/w/pxeload. That should work.
If it doesn't file an issue.

And are there instructions for bootstrapping such a nix system?
It builds fine here now, but I have no idea how/what to put on disk to
make it boot.

does 9load do enough to boot the nix 64-bit kernel?

[Fco.J.Ballesteros]

Sorry, I was trying to say that looks like the kernel had to setup its
boot page table, etc. before 9load arrived. ---I was not referring
to loading the kernel; again, sorry if the text says that.

In any case, I'd love to see the answer to your question  ☺.

I'm looking at the p9 bootstrap sequence (mostly trying to get
acquainted with the asm) and I see lots of similarities between

/sys/src/boot/pc/l.s
and
/sys/src/pc/9/l.s

francisco balestros indicates in his 'notes on p9' that the kernel may
have done the loading itself in a previous reincarnation of the system
(page 32 of his notes, right on top).. if that indeed is true, how was
the bootstrap sequence organized then?

  I've just downloaded plan 9, made the disk, burnt the 50mb file to an
  iso9660 CD, and each time I boot the floppy, I get a different problem.
  Last time, it was "exception/interrupt 14", this time, it's stalling
  after saying "dev A0 port 170 config 8080 capabilities 0700 mwdma
  0007".  Any ideas?

If you have a network card configured, disable it
by removing the ether0 line in a:\plan9.ini.
I had some problems similar to ones you describe
when using a 3c905 that the driver hadn't seen before:
it was treating it as an earlier card, and spinning waiting
for a bit to clear that never would.

Typing ^t ^t p (ctl-t, ctl-t, p) during the stall may
print the kernel's version of ps (if interrupts aren't
disabled).
