Stepping is Intel teminology for chip revisions - possibly other
manufacturers have used the same terminology. Intel documents the fixes,
or rather the bugs and work-arounds, for each stepping level in the
addendum to the particular processor's reference manual. Probably, I
haven't checked, this info is available in PDF format from the INTEL
website (http://www.intel.com).
IBM terminology for the equivalent of stepping level is EC level
(engineering change level).
To understand the fine detail of the intel stepping levels, in particular
the work-arounds, you'll need to be familiar with the processor
architecture to the extent an assembler programmer would be.

Subject: cpu stepping
hi,
sorry to ask this here but i'm finding difficulty getting this info
elsewhere...
I'm not an assembly programmer and i know little about cpu's. it's a hole
in
my knowledge i guess. i'm looking for some technical introduction doc to
explain what diff. aspects of cpu do, what is stepping and all that.
especially for intel but also for other architectures.
Thanks
Jon
