Thanks.  OK, I've just rebooted.  8-)  It works, kind of.

The prompt I get from the first-stage (I assume) bootloader is

1: <[A

where the < is actually a graphical left-pointing arrow.  Hitting
space here produces "Error ?" or something similar; enter gets me
to biosboot (again, I think).

I'm willing to try patches to fix this, otherwise I may dig around
myself.  Googling shows similar reports of garbage characters with
recent bootblock updates so I don't think I'm the only one.
