Hi,
BIOSes is an area where accessibility is approximately non-existent. Asking vendors to support hardware speech syntheses and braille devices is quite dreamwork. I tried to convince accessibility people to release basic drivers with BSD licenses so that vendors might integrate them, but they just refused that, arguing that vendors will not make any effort to integrate them, and there will always be bugs (which are hard to debug/fix/integrate/... with vendor BIOSes).
LinuxBios, however, can be a great opportunity to have an accessible BIOS.
So what can be done? If I understood well, LinuxBios is a linux kernel -based bios. Does that mean that it has the notion of process, or does it run only in kernel mode? (which is sufficient for taking advantage of linux drivers).
