The PODP ???

You mean there are actually people who use them ?
You got one yourself ? Well, that's a difference :)

Honestly, I totally forgot about that chip, and it
makes my idea look even worse ...
I had already come to the conclusion that it wasn't
worth the complexity, and had been thinking about 
backing out that change. 
(I wondered about the Cyrix 6x86 cpu, for example, 
which isn't detected as an I586_CPU, AFAIK, but goes
into the same motherboards as a Pentium. This would 
be a CPU that claimed to be a 486, but needs the P5
chip set names. The opposite of your situation with 
the PODP ...)


You'll get your chip set message back. I promise!
