Fast Boot is a feature in BIOS that can help to reduce the time it takes to boot Intel® Desktop Boards.
The Fast Boot option has three optimization settings which allow General, USB and Video Optimization to be turned on or off separately. By default, all Fast Boot options are disabled.
To enable Fast Boot:
- During boot, enter the BIOS setup by pressing F2.
- Go to the Boot menu.
- Enable the Fast Boot setting.
- Enable any (or all) of the three Fast Boot options:
- General Optimization
- USB Optimization
- Video Optimization
- Press F10 to Save and Exit.
| Setting |
Description |
| General Optimization |
If you enable General Optimization, the system will boot faster because the following features will be disabled:
- Boot to Network
- Boot to Optical Devices
- Boot to Removable Devices
RAID devices will still be bootable, but not configurable. |
| USB Optimization |
If you enable USB Optimization, all USB devices will be unavailable until after the operating system boots but the system will boot faster.
- If you are using a USB keyboard, entering BIOS Setup by pressing F2 will not function. See Recovery Steps below for instructions on how to disable Fast Boot without using a keyboard.
- USB Optimization cannot be enabled if a User Password or Hard Drive Password is installed.
|
| Video Optimization |
If you enable Video Optimization, the BIOS will display text only (a custom logo will not display) but the system will boot faster. If disabled, the BIOS will display the logo but will boot slower. This does not affect video capabilities after the operating system boots. | |
Recovery Steps
Fast boot recovery
The BIOS is able to determine if the previous attempt to boot was unsuccessful. When the computer is booted, if the previous boot failed during POST, Fast Boot will be disabled and the following message is displayed: "The previous boot attempt failed. Would you like to restore Fast Boot on the next boot? (Y/N)". If the boot attempt fails after POST (OS boot failure etc.) no message is displayed and Fast Boot is still active.
Power button recovery
The power button can be used to recover if you encounter Fast Boot problems.
- From a powered off state, press and hold the power button for approximately 2 seconds (release it when you hear 3 short beeps).
- The BIOS will follow a normal boot path as if Fast Boot were disabled.
- If Fast Boot was enabled, the following message will be displayed: "Fast Boot failsafe trigger was detected. Would you like to restore Fast Boot on the next boot? (Y/N)".
Back to BIOS recovery
This method can only be performed on Intel® Desktop Boards that include the Back to BIOS feature. It is triggered by pressing a button on the back panel of the board. When this button is triggered, it will light up and the BIOS will follow a recovery boot process. It forces the BIOS to boot directly into the BIOS Setup, where you can disable Fast Boot if needed.
BIOS recovery with the configuration jumper
This method can be performed on any Intel desktop board.
- Refer to your board’s Product Guide or Technical Product Specification for the location of the BIOS configuration jumper.
- Move the jumper from Pins 1-2 to Pins 2-3.
- Turn on the system and it will boot directly into the BIOS, where you can turn off Fast Boot if needed.
Note on A/C power loss
If Fast Boot is enabled and your system loses A/C power during the POST process, the board will detect the A/C power loss on the next boot and you will receive the message "The previous boot attempt failed. Would you like to restore Fast Boot on the next boot? (Y/N)".
