I was thinking of the chain of emails at:
My (new) thinking is that we could:
* Continue to have seabios be a coreboot payload
* Have seabios find, copy, and run options roms on pci cards. Have it
scan the lar for pci devices with option roms embedded in flash.
* Teach seabios to be able to launch a payload from flash in addition
to floppy, hd, cdrom, etc..
The main gain to the above is is that we can keep all the legacy x86
real mode crud (including option roms) in one place (seabios), and we
can avoid having to return from seabios to coreboot and thus not have
to worry abou them "stomping" on each other.
