Bus Types

The chipset dictates what sort of buses the system can support; in fact, Intel calls its chipsets "PCIsets" and "AGPsets". Most modern PCs support the ISA and PCI buses, but older chipsets (on 486 class machines) support the VESA Local Bus (VLB) instead of PCI. There are even some 486 PCs that support all three buses on the same motherboard. The newest PCs also add AGP for video.
