you need to tell the kernel where your root is. From milo:

boot sda1:/boot/new-kernel-image root=/dev/sdXX

If you're really stuck, try 

boot sda1:

which will look for a /etc/milo.ctl file. (sort of equivalent to
lilo.conf on i386)

use the 2.0 based ones from genie.ucd.ie. And once you have a working
milo you shouldn't ever really need to change it.

the milo build does a lot of magic after compilation to try reduce the
size of the image and massage it into the appropriate format. Seems to
be a fragile process though - it always broke at one particular place
for me.

(does a clean compile work for you? ie make clean ; make)

Also: you have a DEC machine, so you don't need milo. You could use SRM,
which is much cleaner. (see the SRM and aboot HOWTO's).

Finally, for linux-alpha help you're probably much better off asking on
axp-list at redhat.com or linux-alpha at vger.rutgers.edu - those 2 lists are
dedicated to Alpha.
