Table 6-3 Computer Setup Advanced (for advanced users) (continued) Option Heading Lets you enable specific serial ports. Default is enabled. Serial Port Voltage (Retail Point-of-Sale models only; ports vary by model) Lets you configure powered serial port voltage selection on RPOS units that include this feature. Default is 0 Volts. ● 0 Volts ● 5 Volts ● 12 Volts Cash Drawer Port (Retail Point-of-Sale models only) Controls whether the cash drawer port can be activated. Default is enabled. Restrict USB Devices Specify the following categories of USB devices to enable: ● Allow all USB devices (default) ● Allow only keyboard and mouse ● Allow all but storage devices and hubs. When some devices are restricted, the system will disable USB ports that do not meet the allowed criteria. This feature is usually combined with similar policies within the operating system because USB devices can be moved to different ports. The ports disabled by the BIOS remain disabled until the system is restarted. Power Management Options Runtime Power Management Allows certain operating systems to reduce processor voltage and frequency when the current software load does not require the full capabilities of the processor. Default is enabled. Extended Idle Power States Allows certain operating systems to decrease the processors power consumption when the processor is idle. Default is enabled. S5 Maximum Power Savings Enabling this feature reduces the power of the system as much as possible in the S5 state. Power is removed from the wake up circuitry, the expansion slots, and any management features while in S5. Default is disabled. SATA Power Management Enables or disables SATA bus, device power management, or both. Default is enabled. PCI Express Power Management Enabling this option permits the PCI Express links to use Active Power State Management (ASPM) to enter lower power states while not in use. Default is enabled. Power On from Keyboard Ports When enabled, this feature allows a key press to turn on the system when it is off (S5 state). If using a USB keyboard, you must plug it into one of the rear ports labeled with the keyboard icon. Default is disabled. Unique Sleep State Blink Rates 70 Chapter 6 Computer Setup (F10) Utility
