Asus has decided to do something about that requirement in rather inventive fashion. The CT-479 is an adapter card that plugs into the processor socket of certain Asus Socket 478 motherboards and converts them to a Socket 479 configuration capable of accepting a Pentium M. This adapter neatly solves both the price and performance issues, the latter by supplying a dual-channel memory configuration unavailable in the Intel 855GME laptop chipset.
