I rawrited a floppy and tried to boot.
This is what happens

VMS PAL revision ...
OSF PAL rev: ...
Switch to OSF PAL code succeeded

Boot flags:

Loading netbsd...
open netbsd: No such file or directory

Loading netbsd.gz
3849336+882560 [85


and then the screen blanks.  the floppy is no longer being read and the
computer hangs.  is something supposed to happen here or am i supposed
to do something.  nothing i type seems to make a difference.

this is an alphastation 200
