'make zImage'
on an noname box. (Please specify clock freq).
I'm well aware this is a benchmark on the quality level of bogoMIPS,
dependent on very many factors and not comparable to an Intel box, but
it would give a nice feeling for what some of power to expect.
(For an easy bottom line to beat, my 386sx/16 4Mb notebook takes more
than 2 hours for a minimal kernel.)
Thanks in advance,
Tommy
