It's true that most BIOSes are proprietary and we're against non-free
firmware. Unfortunately, however, most motherboards around aren't
supported by any free firmware so we have to cope with what we have. We
encourage you to use motherboards with free firmware. I'm aware of 3
categories of such:
1) Coreboot has made a great job in freeing x86-based mobos. You can
consult their list here:
2) Touchbook by always innovating claims to use U-Boot and
supply the complete sources. I haven't checked this claim however
3) Yeeloong by Lemote It
uses PMON, soon GRUB will work as firmware on it too (big parts are done)
On BIOS grub uses its interrupts by default because this interface
usually supports the hardware user has and on coreimg stage it allows to
shave off few bytes. However we move to using our own drivers since
firmware interface is often buggy and/or incomplete.

GRUB doesn't link with BIOS
