Hmmm, if the BIOS is gone when the kernel is started, how do I get
that information out of the BIOS?  Don't I need that to find out where
the tags start?  I notice the PICA and Jazz based machines check a
register that the R4400PC doesn't seem to have :-(.

Oh good.  Sure wish that standard wasn't (C) Microsoft.  I'd want a
copy :-(.
