That is not my experience.

E.G. generic ide CDROM do not boot on U5s or AX boards.

IPX,Classic,SS10,SS20,U2,AXi require 512 byte block support.

May be all the machines I've put my hand on are peculiar ...

As for Symbios controllers, again without firmware I can't see how they 
can boot. My 53c815 certainly doesn't. But if someone explains me how to 
get it working I'll be happy to learn.
