Vimage Vpower PB 1400 G3/233 Cache Control Driver
This is a VERY hard to find driver that enables the cache on this CPU upgrade. The card works without it but is barely faster than the original 166mhz CPU. I couldn't find this anywhere online and had to get the original owner of the upgrade card to rescue it off an old floppy for me. Please mirror this so it doesn't get lost!
