I was surprised to not have seen anyone else with this problem. Hopefully
it's not something stupid that I've done. Any idea of how many people have
actually already started booting from flash? There seems to have been many
people talking about how well it has worked for them. Anybody reading this
that have upgraded to a 40GB IBM Travelstar and are not having any problems
booting from flash?

Actually, I get 0x200 when I check in the HW Info debug screen in normal
operation. Should these be the same?
