Please explain why, otherwise we can't help you much.

First, LB has no USB drivers. You could move what is in FILO over
More relevant is the fact that LB can't allocate resources to
hardware that does not exist. Unless you have the controller itself
it's not possible to set any resources. They are set in registers
(RAM) that is mandatory for PCI cards to have (the so called PCI
config space) and no card means nowhere to set things.
Furthermore, option ROMs are not really "compatible" with LB, the
idea is to try to use existing open source drivers with LB instead of
binary blobs with broken interfaces.
So - what do you want to accomplish with your idea? There may be a
better way to do it, or it may be best to forget the whole thing.
We can't say without more info.
This is for my MS project. We want to simulate a PCI card and use one of the CPU cores to do our processing. We would also want to reserve that core.
We want to create the dummy pci device so that OS driver can communicate with the emulated card. What methods would you suggest?

I found your website by accident, I was looking for a way to flash the ROM of
my Samsung I600 so I can install Linux on it (It's a project I want to do)...
I am a programmer but I'm completely new to this...
That's why I was wondering if I can use flashrom to flash the ROM of my

How about AMD ?
Hi LB Gurus,
I want to place an option ROM image on a raw USB flash drive. It will be an option ROM image of a proper controller with correct option ROM and PNP headers.
How can we make linuxBios to look for this drive and allocate dummy pci resources like bus 0 dev-xx, fun yy and irqs?
Thanks a lot for your time.
Don't let your dream ride pass you by. Make it a reality with Yahoo! Autos.
I have a Chaintech Apogee 7NJL1 board, still unboxed. It has an Nvidia
nForce2 chipset, an ITE IT8712F superio chip, Socket-A (AMD K7) cpu slot
and a socketed flash chip.
It has lot of goodies inside, see for example
http://www.motherboard.cz/mb/chaintech/7NJL1.htm for detailed listing.
As K7 motherboards are not supported (according to the wiki), this would
be a good challenge to add code for it, while the chipset has probably
already support in LinuxBIOS v2 making the job easier.
I am willing to donate this to someone doing the job. Also I am seeking
a donation: a board which is already (partly) suppoted by v2 and can
accept an Intel CPU with SSE3 (preferably SSE4) support (as a plus it
could have a socketed flash chip :).
