Power Button Menu
As an alternative to Back-to-BIOS Mode or normal POST Hotkeys, the user can use the power button to access a menu. The Power Button Menu is accessible via the following sequence:
- System is in S4/S5 (not G3)
- User pushes the power button and holds it down for 3 seconds
- The system will emit three short beeps from the front panel (FP) audio port, then stop to signal the user to release the power button. The FP power button LED will also change from Solid White to Flashing White when the user can release the power button.
- User releases the power button before the 4-second shutdown override
If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where possible.
At the point where Setup Entry/Boot would be in the normal boot path, the BIOS will display the following prompt and wait for a keystroke:
[ESC] Normal Boot
[F2] Intel Visual BIOS
[F3] Disable Fast Boot
[F4] BIOS Recovery
[F7] Update BIOS
[F10] Enter Boot Menu
[F12] Network Boot
[F2] Enter Setup is displayed instead if Visual BIOS is not supported.
[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.
If an unrecognized key is hit, then the BIOS will beep and wait for another keystroke. If one of the listed hotkeys is hit, the BIOS will follow the indicated boot path. Password requirements must still be honored.
If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the system.
