well, that's ok. I've been doing OS for years. If you look inside the
kernels long enough, you'll find that the bios did not help you as much as
you think. It tends to get things wrong. Also, there are things you'd like
to be able to do that you can't because companies like Intel hide them in
proprietary BIOS code.

I have to say, having done OS porting and development in both BIOS and
non-BIOS environments, I've found the non-BIOS actually much easier. The
assembly code hackers who write BIOSes are not all that good, and they are
certainly not concerned about making life better for us open source OS

Your comment about loadables really has no relation to BIOS or
non-BIOS. those are very different issues.
