Yeah, I'm starting to realize that (remember back to when I first looked
that Intel codebooks). The paging is definitely a major plus, along
other things.
I think I conceded it in this post:
http://www.redhat.com/archives/fedora-devel-list/2004-June/msg00039.html
"The rule of thumb is, everything that can be built for 386 ISA,
should be built for it. Optimize for 686 architectures (PPro/II+,
Athlon, etc...), but make it 386 ISA compatible. If that is not
possible (e.g., NPTL), then 486 ISA."
But otherwise we agree on the "target 486, optimize PPro"?

240MHz sounds more like a WinChip2 with the pipelined FPU?
But if you say it's an original WinChip, I'll believe you.
