Wrong assumption. The long term plan is to call the linux driver
to boot off of cards. The linux kernel will be used in our bootloader.
I am in the process of working out the size constraint issues.
The perception of a significant chunk of our customer base is that if
you can't do it from linux you can't do it. So classic PC-BIOS
firmware compatibility is simply a nice to have, and I don't see it
extending beyond an optional feature.
Video cards have a special place in nuisance list. But what
a video card requires from firmware is different from what a RAID card
with a menu to configure things requires. And even the video card
BIOS support will be optional.
