Does the 430TX support AGP?
Chipsets that do support AGP, such as the 440BX, has a secondary internal arbiter within the chipset, exclusive to AGP. This second arbiter works directly between the graphics device and memory, improving performance. Without the arbiter, AGP cannot be used, since it cannot operate fast enough. Chipsets such as the 430TX do not have the additional pins required to connect a separate AGP controller for the chipset. There are AGP connectors for the PCI bus, which provide AGP support. These connectors are available through Third Party Vendors, not from Intel.
