Table 2-4. Onboard Devices Options Option Integrated NIC (On default) USB Controller (On default) Front USB Ports (On default) Serial Port #1 (Auto default) Description Enables or disables the integrated Network Interface Controller (NIC). Off disables the controller. On enables the controller. On w/PXE enables the controller with PXE. On w/RPL enables the controller with RPL. NOTE: PXE or RPL is required only if you are booting to an operating system on another system, not if you are booting to an operating system on a hard drive in this system. Enables or disables the internal USB controller. Off disables the controller. On enables the controller. No Boot enables the controller, but disables the ability to boot from a USB device. NOTE: Operating systems with USB support will recognize USB storage devices regardless of the No Boot setting. Enables or disables the front USB ports independently of the rear ports. Off disables the controller. On enables the controller. No Boot enables the controller, but disables the ability to boot from a USB device. NOTE: Operating systems with USB support will recognize USB storage devices regardless of the No Boot setting. Serial Port 1 options are COM1, COM3, Auto, and Off. When serial port 1 is set to Auto, the integrated port automatically maps to the next available port. Serial port 1 attempts to use COM1 first and then COM3. If both addresses are in use for a specific port, the port is disabled. When serial port is set to COM1, the integrated port is configured at 3F8h with IRQ4. When the serial port is set to COM3, the integrated port is configured at 3E8h with IRQ4. If you set the serial port to Auto and add an expansion card with a port configured to the same designation, the system automatically remaps the integrated port to the next available port designation that shares the same IRQ setting. Table 2-5. Performance Options Option Hyper-Threading (On default) Multiple CPU Core (On default) Description Determines whether the physical processor appears as one or two logical processors. The performance of some applications improve with additional logical processors installed. On enables hyperthreading. Off disables hyperthreading. If the processor has multiple cores, specifies whether the processor will have one or two cores enabled. The performance of some applications will improve with the additional core. Off disables Multiple CPU Core Technology. On enables Multiple CPU Core Technology. Using the System Setup Program 31
