thanks, I already figured this out. The actual commands were:

Fixit# dd if=/dev/zero of=/dev/da0 bs=512 count=32
32+0 records in
32+0 records out
16384 bytes transferred in 0.445921 secs (36742 bytes/sec)
Fixit# bsdlabel -w da0

I'm thinking of adding a short paragraph on this under
4.2 Common Installation Problems for Alpha/AXP Architecture Users
in FreeBSD/alpha 6.2-RELEASE Installation Instructions
http://www.freebsd.org/releases/6.2R/installation-alpha.html
(that section is empty at present).

thanks a lot
