The serial console support seems to be conditionally compiled out
of the biosboot.sym build.

I'm not sure why, but it is possibly due to space constraints.
(I added ~200 bytes of code and got the stack crashing into data.)
A little bit of work recovered about 10k of code/data space,
so with those changes maybe the serial console support could
go back in? (I haven't looked at all the differences though).

I had a thought of making the bootloader read (say) /boot_cmds
when it times out and issue the command from it, and only
issue 'boot' if the file is absent.
