The CPU on the test board has sSpec SL5ZF:

The one in my "main desktop", I don't remember the sSpec but it is
definitely a 6B4.
A third one has sSpec SL68G:

That's a 6B1.

So yeah. :)

The CAR thing is promising! While we're talking about cache, Is CAR supposed
to use L1 or L2 cache? Also how did we know the L2 cache isn't enabled on
440BX boards as noted on the wiki? I'm under the impression that once the
caching is configured in the CPU, both levels becomes enabled?

Cheers
