Wouldn't an easier solution be a program that could read from, and write to, the bios, that could be accessed from an already booted computer regardless of the OS? In my convoluted way of thinking, it wouldn't then matter which means of accessibility you are using, you could make changes to the bios and have them take effect on reboot. Take effect on reboot! HHHMMM!!! What a concept, isn't that when changes to the bios currently take effect? This approach then would not need manufacturers having to worry about making something to work for all. OH Yeah, maybe we are barking up the wrong tree completely on this one. Earlier this year, I read an article that was talking about the bios as we currently know love is going to be replaced by some new system that will be accessible from tools within the OS. This is because of the 16-bit restriction that currently exists in the bios, or so the article was saying. If I have some time latter on today, I'll try to find the article and post it here as another follow-up to this thread.
