this is more or less how the alpha does things (well at least on a PC164LX)
there is a great big flash memory divided up into 8 segments
the first contains the "last resort" hardware monitor
the rest of the segments can contain alphabios or milo

alphabios only knows about dos filesystems and is for NT
this is used to load milo from a dos filesystem
milo is a boot program which is built using linux device drivers
it can know about any device for which there is a linux device drive

milo *can* be loaded into the flash instead of alphabios

seems like this could work here
after all - the DEC guys presumably went through the same thought processes as we
are going through on this list - their solution is quite good

now (being an alpha newbie) this could be all wrong in subtle ways
if (and there definitely is) there is someone more knowledgeable about alpha who
can correct the above description - please do so

comments/flames please
