The 333i+, based on the 440LX chipset, is limited to CPUs which run at 66MHz
front-side bus. The fastest ever 66MHz FSB CPU is the 766MHz Celeron, a Socket
370 beast. But if the 333i+ BIOS gets in the way, well, then the 333s are it.

I ran into similar difficulties with Intel's (!) 333MHz Pentium Pro OverDrive
installed in a Celebris 6200. It just did not work right.

I can only suspect that the late Phoenix BIOSes used in the ivory white products
suffered from various limitations and defects which were never overcome so late
in the life of an autonomous DEC. This is more than a suspicion. It's fact.
The Celebris 6200 was unable to use the full capacity of an 8.4GB IDE drive, and
required manual settings for cylinders, heads (max of 15) and sectors/track to
use 8GB. And Compaq only hastened the demise of anything with a DEC label on
it.

If you really want to push the Multia, running the risk of burning out some
motherboard component or other, I'm fairly sure that a genuine AMD K6-2 rated at
400MHz can be coaxed to run at full rated speed with the right jumper settings.
I've managed to achieve this on some other Socket 7 motherboards... Ben Myers
