It's not a secret that Intel has some problems with delivering enough entry-level chipsets and Tom's Hardware Guide recently wrote Intel will use ATI's Xpress 200 chipsets for its Intel-branded motherboards.
ATI has the Xpress 200 IGP in the market for about 10 months (7 months for Intel platforms). As it appears, Intel now has decided to use the Intel edition of the chipset for entry level boards, most likely upgrading the 845/865 AGP-based boards as well as supporting 915GL PCI Express boards. In either case, Intel will integrate the Xpress 200 in an Intel-branded, entry-level board.
Additionally, Intel may also use chipsets from SiS according to some sources.
