**Cant find a chip?
Early chip sets have a title and a part no. to refer to the chip set
as a whole. As time went on the chip set became one chip, so later
chip sets are usually referred to by the part no. on the actual chip.
These are usually called "Single Chip" by the manufacture, although
they nearly always follow the 2-chip North/South-bridge paradigm. So
these are referred to by for example, "M1521/M1523" or "M1521/M23" for
short. If there is a part number for the chip set as a whole that has
precedence. Try the search function for a chip part no. and hopefully
it will turn up the chip set it was part of.
