Unfortunately OpenBIOS is not ready for prime time yet. I am currently
working on the forth engine and trying to fiddle vocabularies support
into it - one big step towards Package (driver) support.

You might want to have a look at LinuxBIOS though: www.linuxbios.org.
It can be used together with an etherboot payload to boot a kernel
loaded via tftp. (I'm doing the same thing on a Geode system)

Stefan,

Many thanks for your useful answer. I do not quite understand
the difference between openbios and linuxbios, to the
uninitiated like me they sound like the same thing. I actually
want to eventually boot RTEMS, but am using Linux to test
the application first. But from the web site I see that I can
boot RTEMS after the linux in the bios. Great...
