 PCI Latency Timer
This item controls how long each PCI device can hold the bus before
another takes over. When set to higher values, every PCI device can
conduct transactions for a longer time and thus improve the effective PCI
bandwidth. For better PCI performance, you should set the item to higher
values. Setting options: 32, 64, 96, 128, 160, 192, 224, and 248.
 Legacy USB Support
Selecting Enabled allows users to use USB devices, such as mouse,
keyboard, or portable disk, in DOS system; or allows users to boot the
system by USB device. Setting options: Auto, Enabled and Disabled.
