Dear Jack,
Can OpenBIOS be used to initiate tftp booting across the ethernet? The alternatives of making a eprom memory strip, or having an eprom in the NIC, are more expensive and time consumming, so I am keen to use OpenBIOS for this.
I have looked through the news history, and the web site and still cannot find the answer. (but of course that doesn't mean much)
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)
