Cool. Where do I get the x86 BSP? And isn’t the term “BSP”, a
WindRiver’ism?

QNX has everything you need to replace the BIOS in the h/w specific IPL.
(Or at least, it gives you a starting point).
You will need the x86 BSP though.
Once you can get QNX to boot, DOC support is trivial to add.

Alex,
The CPU that I am using has a PLCC ROM that has the BIOS in it, and a
flash
BIOS that is user programmable with a provided programming utility. With
a
jumper, you can select which one to boot from. Theoretically, I could
test
my updated BIOS replacement in the flash area and if it doesn’t work,
move
the jumper back to ROM to recover if I screw it up.
The problem that I have is that I don’t know where to begin, with
respect to
writing my own BIOS. Further complicating matters is that I’d like to
take
advantage of the Disk-On-Chip capability of the board. Is there a
“writing
QNX boot BIOS for dummies” anywhere?

It’s been really quiet here. I was hoping for some wisdom on
yanking my
BIOS off of a PC/104 x86 derivative. Does any of that exist?
John
Getting rid of the BIOS is a really ambitious project, and something I
wish I had
time or better yet, a paying customer for.
The Jumptec (> www.jumpte.de> ) range of boards offer something called
JRC,
with which
you can overwrite the onboard flash, and therefore potentially the
BIOS.
DSP Design has a similar facility (> www.dspdesign.com> ).
Good luck

Ok what have been peoples experience so far in say puting a
minimal
qnxrtp/neutrino/photon on say a x86pc with a 72MByte Disk on Chip
and
how
did they do it.
I battled with this for some time and succeded in a fashion, so if
we
can
collectively come up with a GOOD solution highlighting the traps
this
may
be
a good start to an embedded news group.
