The latest SiS roadmap shows that SiS649FX and SiS656FX chipsets
are able to support 1066FSB and DDR2-667. EM64T, XD, EIST Technologies are ready
on all of SiS P4 chipsets. Dual core technology currently under validation will
be ready on all of SiS P4 chipsets. On the AMD front, SiS761GL chipset is added to support AMD K8 entry level
platform. Also 64bits and dual core technologies is ready on all of SiS K8
chipsets. SiS966 and 966L Southbridge are able to support High definition Audio and
