Subject: Any experience with bootrom for PCI boards ?

Has anyone experience in building a netboot ROM for a PCI board ?

Apparently (from Shanley's "PCI sytem architecture", fresh from
the bookstore) ROMs mounted on a PCI board require some special
header to work. The problem is, they appear to work with only a
single PCI board as they must match both the VENDOR and DEVICE ID
(this is a bit boring! a nice thing of the FreeBSD ROM is that it works
with a number of different boards. With the PCI ROM, you can have
multiple images in a single ROM, but it seems that you are not allowed
to have a single image for a number of different boards.)

I think I have figured out a way to do it (a bit boring, though),
but I am wondering if someone else has had a similar experience
and in case can share his knowledge -- unfortunately, there is no
way to tell what is going wrong when the ROM is not recognized!

	Thanks
	Luigi
