Glad you're happy - you've been lightly badgering me to do two stage
bootblocks for long enough :-)

Ahh, so I can just copy what you do. Thanks :-)

Michael Hitch has toyed with the idea of doing a fixed block stage one,
more for proof of concept than anything else. On the pmax, it should be
_extremely_ simple - the first sector contains a "boot map", that lists
61 groups of continuous blocks, a load address and an exec address...
