The beginning of the boot messages would be nice.

This happens then the initrd is empty, either because of a problem
with silo loading it, or a problem with the kernel overwriting it.  If
the kernel is overwriting the initrd, it will say at the beginning of
the boot messages.  If silo is having problems it should say before
the kernel boots (before screen goes black, if you are using a
graphical console.)


Possible problems:

 * You didn't use the latest patches that I sent you, which moves
   "install" from slink1/ to boot1/ before creating the first CD image.
   (This will give an Read Error from the PROM, before the kernel
   starts booting.)

 * The ram disk is getting overwritten.  (This would have to be
   because of a bug/oversight in silo's second stage loader - IIRC,
   you will see a message about this at the very beginning of the
   kernel messages.)
