Jeff Hsu (who did the initial port of NetBSD/alpha to AXPpci33-family systems) was running his AXPpci33 with only 16M, with the standard Digital SRM console. SRM is a pig -- it eats 2M right off. MILO apparently does better than that, but that's because of the console software, not the PALcode. In my opinion, you'd have to be ... brave to try and use an Alpha with 16M anyway, but there's no denying that the SRM eats more memory than it "should." cgd
