I'm using xen-unstable, and I've successfully made a passthrough of an
intel storage controller to an HVM domU, binding with pciback.

00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset
Family SATA AHCI Controller (rev 05)

I can access the array from within Windows by installing Intel Rapide
Storage Drivers, and everything works as it should.
I only have a small problem, I would like to boot the guest OS directly
from the controller, but of course since there's no "option rom" loaded in
the qemu bios, it doesn't work, because the boot manager can't access the
array without drivers loaded.

I was wondering, is there any way to let qemu load the option rom of the
controller so I can boot from it?
Is there any other storage controller which the option rom get
"passthroughed" too? I hope I've been clear enough.

Thanks, Ivo
