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 anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423
