I had the same problem with my alphastations which previously ran Linux
and Tru64. For future reference it's generally more helpful if you
provide more information about a problem, such as a verbose boot output
(assuming you are using a serial console and can cut'n'paste). If
however your problem is that once you start sysinstall you get:

da0: start 0, end 2050859, size 2050860
da0c: start 0, end 4294967295, size 0
da0: raw partition size != slice size
da0: start 0, end 2050859, size 2050860
da0c: start 0, end 4294967295, size 0
da0: invalid primary partition table: no magic

or something similar then:

you need to wipe the partition tables on the disk. I tried doing this
from the fixit prompt using the cd but it didn't work. If you still have
a *nix os on the disk the boot it up and do:

dd if=/dev/zero of=/dev/da0 bs=10240 count=10

(where da0 is the disk to do). If not, you will need to stick it in
another system or find a friend with one. The install went fine after
that for me. The machine has been fairy stable in the 3 months I've had
it, although it has crashed a couple of times whilst running mysql under
heavy load.
