Shuttle SN25P
The SN25P is Shuttle’s endeavor in to the wonderful world of the nForce4 chipset. Read on to find out just how good a job they did with their latest Athlon64 based XPC.
BIOS
The SN25P uses the ever-popular Phoenix AwardBIOS design as a base template. The BIOS version shown below and used in testing was version s907.
The Advanced BIOS Features menu contains numerous boot related options, including those options for configuring the order of boot devices. If a USB 2.0 hard drive device is attached to the system at boot time and is properly detected by the system, it will show as a selectable device within the Hard Disk Boot Priority submenu. The priority of specific items in this menu can be changed using either the + and – keys or the PageUp and PageDown keys.
The Integrated Peripherals menu contains a series of submenus for configuring the various onboard system devices. The Onboard IDE Device submenu contains options for configuring the IDE and SATA ports, as well as a submenu for configuring the chipset RAID controller. The RAID Config submenu contains all options for enabling the RAID controller itself, as well as enabled individual devices for RAID type operation. Notice that all IDE and SATA ports, including the IDE master and slave channels within a single IDE port, can be individually configured for RAID operation. If a port is configured for RAID operation, it will not be detected on system initialization, but will show as available through the NVIDIA RAID BIOS. The Onboard SuperIO Device submenu contains options for configuring the floppy controller, as well as the serial and parallel ports. The Onboard PCI Device submenu has options for controlling the onboard USB 2.0 ports as well as the LAN port.
The PnP/PCI Configurations menu contains options for configuring the system IRQ and PnP related settings. The BIOS does not offer specific control over the individual IRQ settings, but does offer IRQ pool assignment configuration. With the Resources Controlled By option set to Manual, the IRQ Resources submenu becomes accessible. The individual IRQ pool assignments are configurable through this submenu.
The PC Health Status menu is a centralized location within the BIOS for real-time statistics on all BIOS monitored voltages, system temperatures, and fan speeds for fans connected to the various onboard fan headers. In addition, the speed of the system fans can be controlled through the Advanced CPU Fan Setting option. The Smart Fan setting allows for temperature controlled automatic setting of the fan speed, with the fans running full speed when the CPU temperature exceeds 80 degrees C. The Noise Control options allow for static fan speed setting. The eXtreme PC Mode options set a target CPU temperature that the system attempts to match by dynamically adjusting the fan speed.
