If I understand right, the "bootstrap" section (presently called
LinuxBIOS) is essentially a stripped-down Linux kernel with some rather
more in-depth device initialisation capabilities. Such a configuration
does make sense, and would allow very flexible boot device support.
If this is true, then as a kernel it *does* have callbacks, and can
justifiably be termed a BIOS in the strict sense of the word, even if
it doesn't provide the legacy "IBM compatible" calls to run M$-DOS
directly. Thus the name "LinuxBIOS" should probably stick.
Since I'm not heavily involved with the project, I might have got these
details very wrong. Please don't shoot me too much.
The combination of LinuxBIOS with a trivial "chainloader" payload for
booting a sophisticated OS directly, should probably stay as LinuxBIOS.
As for the combination of LinuxBIOS with an OpenFirmware-like payload,
I think it could be called LinuxFirmware.
The latter could be an extremely powerful system configuration tool.
Certainly overclockers would love it, with a (relatively) universal
interface to and support for their favourite tweaks. Sysadmins would
like it too, if it contained sophisticated diagnostic routines
(Memtest86 and 'badblocks' in firmware?) etc.
Eventually, even Intel will have to admit it's time to ditch the old,
frequently buggy and restrictive AMI and Award BIOS structures.
Goodness, BIOSes of both kinds have caused havoc when faced with a HD
slightly larger than was expected at the time of manufacture, multiple
times in recent history. The onus has largely been on the HD
manufacturers to work around the BIOS bugs. That's just wrong.
