"The KK266-R motherboard is based in the new VIA KT133A chipset. The KT133A chipset is the same as the original KT133 chipset only this new baby supports official 266MHz FSB using PC133 SDRAM modules. This means this chip has a ½ AGP divider and ¼ PCI divider at 266MHz FSB. The design of the KK266-R board layout and functions are almost identical to the KV200 range of motherboards."
