Thats the one I have (PL-MMX Pro for K6-2 or earlier).
>Have you tried the 3.3v WinChip? Made by Centuar,
I have one I have tried in just the socket (no adapter) as they can
use 3.52V. No boot in either Apple card. However, I really ought to
try them again using the adapter to find out for sure.
In any case, I doubt the Winchip will be faster than the M2 or P233MMX I have.

Speaking of laptops, I have a mobile MMX 266 CPU, and it doesnt allow
the L2 at boot. I wonder why. Is it that different from the regular
PMMX ?

I dont think they can. THe BIOS, as it exists in regular PCs doesnt
exist in a DOS card. The BIOS is loaded at bootup into volatile RAM,
from a file in the resource fork of the PC Setup software (a mac
control panel). This makes getting into the BIOS flat out impossible
unless one could decode whats in the resource fork.
That stinks.
If I could get into the BIOS, I could probably make everything work.
