Hi Ron,
I'm able to build and run LinuxBIOS on EPIA with some treaking on Config.lb. However, it fails to jump to payload(etherboot). I suspect LinuxBIOS is jumping to a wrong location. Is it possible to set ZKERNEL_START in v2? BTW, ROM_SIZE for default setup should be 262144 instead of 512k, since most EPIA doesn't come with 512k flash.

OK, I've committed code that turns on shadow dram in F segment, so PIRQ will work; also committed what should be working SMBUS code in vt8231_early_smbus.c; now the fun begins. I could use advice on:
- what SMBUS bytes we need to care about
- what we should program the north with using those bytes.
- how to do it.
Which is to say, I think I know, but let's get this done in a speedy fashion. Momentum is on our side here.
The EPIA will be a good demo platform.
Why this sudden burst of EPIA work from me? Two reasons:
- I want to encourage people to look at V2, so we need a demo system less complex than the K8 systems.
- We are teaching a tutorial on linuxbios, bproc, etc. and will be doing it hands-on with a roomful of EPIAs, 2 or 3 per tutorial attendee. See: http://lacsi.lanl.gov/symposium/agenda.shtml Come if you want. You can see how we build clusters that boot in seconds. The software we're showing is the same stuff that is running on our 1024-node Pink cluster, and will run on our 1408-node K8 cluster.
