Table 3-4 Computer Setup-Security (continued) Master Boot Record Protects the master boot record from viruses or other corruption. Saves of copy of the current master Security boot record. Setup Security Level Provides a method to allow end-users limited access to change specified setup options, without having to know the Setup Password. This feature allows the administrator the flexibility to protect changes to essential setup options, while allowing the user to view system settings and configure nonessential options. The administrator specifies access rights to individual setup options on a case-by-case basis via the Setup Security Level menu. By default, all setup options are assigned Setup Password, indicating the user must enter the correct Setup Password during POST to make changes to any of the options. The administrator may set individual items to None, indicating the user can make changes to the specified options when setup has been accessed with invalid passwords. The choice, None, is replaced by Power-On Password if a Power-On Password is enabled. NOTE: Setup Browse Mode must be set to Enable in order for the user to enter Setup without knowing the setup password. Computer Setup-Power NOTE: Support for specific Computer Setup options may vary depending on the hardware configuration. Table 3-5 Computer Setup-Power Option OS Power Management Description ● Runtime Power Management- Enable/Disable. Allows certain operating systems to reduce processor voltage and frequency when the current software load does not require the full capabilities of the processor. ● Idle Power Savings-Extended/Normal. Allows certain operating systems to decrease the processors power consumption when the processor is idle. ● ACPI S3 Hard Disk Reset-Enabling this causes the BIOS to ensure hard disks are ready to accept commands after resuming from S3 before returning control to the operating system. ● ACPI S3 PS2 Mouse Wakeup-Enables or disables waking from S3 due to any PS2 mouse activity or a button click only. ● USB Wake on Device Insertion (some models)-Allows system to wake from Standby on USB device insertion. ● Unique Sleep State Blink Rates-Enable/Disable. This feature is designed to provide a visual indication of what sleep state the system is in. Each sleep state has a unique blink pattern. ◦ S0 = Solid green LED. ◦ S3 = 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED) - repeated cycles of 3 blinks and a pause. ◦ S4 = 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED) - repeated cycles of 4 blinks and a pause. ◦ S5 = LED is off. NOTE: If this feature is disabled, S4 and S5 both have the LED off. S1 (no longer supported) and S3 use 1 blink per second. Computer Setup (F10) Utilities 19
