Actually the Vi (AMD 640) chipset that I mentioned in my reply to Martin
Pool will support on board cache of 2 Mb and the new FIC motherboards
using it (2006 to 2011 series from memory) are claimed to be the fastest
socket 7 boards around. I think one of the Shuffle boards also has the
Via chipset. However, this informaton is not total founded as the boards
have been prototypes and have not been seen by too many testers. (See
Tom's Hardware Page for motherboard tests and also information on the 64
Mb problem with Intel TX chipsets etc)
