Assign IRQ for USB Enable or disable IRQ allocation for the USB (Universal Serial Bus). PCI Latency Timer (CLK) This item controls how long a PCI device can hold the PCI bus before another device takes over. Setting the latency to longer periods enables a PCI device to retain control of the bus longer before handing it over to another device. Maximum Payload Size This BIOS feature determines the maximum TLP (Transaction Layer Packet) payload size that can be supported by the motherboard chipset's PCI Express controller. The TLP payload size determines the amount of data transmitted within each data packet. When set to 4096, the motherboard chipset's PCI Express controller supports the maximum data payload of 4096 bytes within each TLP. This is the maximum payload size currently supported by the PCI Express protocol. 44 Chapter 2
