The boot block is the same for all different disk types. Which is nice :-)
Yes, indeed - but Jonny claims the conversion to this sheme broke
preparation of completely zeroed/new disks for 11/750 and others (but
not for micro vaxen, which is the only hardware I have).
Right. Since, if you look in sys/arch/vax/boot/xxboot/start.S, you'll
see that there is actually some code in block 0, and a few different
entry points, which are used by the 11/750, as well as the generic
VMB.EXE. All this code is not written into the disk block 0 by
installboot. But the code in start.S is there for a reason...
installboot ignores that, and instead does a scheme which only works on
the MicroVAXen. :-(
