BIOS Setup Advanced ▶ PCI Subsystem Settings Press to enter the sub-menu. ▶ 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. ▶ ACPI Settings Press to enter the sub-menu. ▶ ACPI Standby State This item specifies the power saving modes for ACPI function. ▶ Power LED This item configures how the system uses power LED on the case to indicate the sleep/suspend state. 3-6
