The 420 series chipsets were the first to introduce the North/South Bridge design.
Fifth-Generation (P5 Pentium Class) Chipsets
With the advent of the Pentium processor in March 1993, Intel introduced its first Pentium chipset: the
430LX chipset (code-named Mercury). This was the first Pentium chipset on the market and set the
stage as Intel captured this lead and ran with it. Other manufacturers took months to a year or more to
get their Pentium chipsets out the door. Since the debut of its Pentium chipsets, Intel has dominated the
chipset market for Intel processors.
Table 4.11
shows the Intel Pentium motherboard chipsets. Note
that none of these chipsets supports AGP; Intel first added support for AGP in its chipsets for the
Pentium II/Celeron processors.
