Well, I'd sort of prefer netbooting as I can then switch between 4.x and
5.x to test things fairly easily. I can also switch to {Net,Open}BSD just
as easily. All of which are appealing :). Especially given the machine
has a single 4G disk.

Thats what I thought, thanks for confirming it :).

Fair enough. The previous experience was indeed trying to move from
AlphaBIOS to SRM.
Thanks for the response. I think I'm going to download and burn the
rescue disk then boot from that and try to build a netbootable kernel
on the Alpha rather than cross-compiling. If that doesn't work I'll
probably obtain another disk and install on that.
