Interesting. I'll be sure to post my notes if and when I do get it
working then. I'd still like to keep hacking on this, as it's a far more
elegant solution than going the adapter route. I was under the
impression that it worked by preventing the kernel from probing for ide2
so that it wouldn't overwrite the config done by linuxbios, but I
obviously haven't gotten that far yet. As for my current issue, I just
read something that leads me to believe that I need to disable PCI
support in filo, but I won't be able to try until later tonight.
My environment right now consists of flashrom and my rom image on my CF
card, which I access from a gentoo livecd. I can't get El-Torito boot
working either (same issue as this thread), so my development cycles
are pretty long atm.
Thanks for the heads up.
