To prevent the Intel® Boot Agent from initializing, turn it off using the Intel® Ethernet Flash Firmware Utility (BootUtil.exe). The utility package contains versions of the utility for DOS, Windows, Linux, and UEFI.
Download the Intel® Ethernet Flash Firmware Utility (includes BootUtil.exe).
These instructions for disabling Intel Boot Agent apply to add-on adapters plugged into a PCI, PCI-x, or PCI Express* slot.
If you have a built-in network connection, then you need to refer to the documentation for your computer. Usually the settings to disable or enable the boot agent are in the BIOS.
If you have a laptop computer then this page does not apply to you. Look in your computer BIOS for settings to disable the Intel Boot Agent.
||The Intel® Boot Agent Guide is included in the Intel® Ethernet Flash Firmware Utility download package. Launch index.htm to open the guide. The guide includes detailed instructions for using the boot utility to disable Intel Boot Agent.|
Installing the Boot Utility
For DOS or UEFI you can run the program from the folder for that OS. If you try to run the DOS version of the utility from the Windows command line, the program will fail to run. The DOS version of the utility will only run under DOS.
For Linux* and Windows* you must first run the install program.
The install and the boot utility programs are in the folder for your OS inside the \APPS\BootUtil folder. If the folder for your OS includes an install program, then you must run install before running the boot utility.
Installing this utility in Windows* overwrites some files required for Intel® PROSet for Windows Device Manager. Installation can cause system bug checks or loss of functionality when using Intel® PROSet or other tools using the same driver. Uninstall Intel PROSet before installing this utility. After you use this utility, reinstall Intel PROSet. Reinstalling PROSet can render this tool useless, because the files used by the utility are overwritten.
How Intel® Boot Agent works
The Intel® Boot Agent is software that allows your networked client computer to boot using an image on a remote server. PC vendors can implement the Intel Boot Agent to accommodate various environments and protocols. The BIOS inserts the Boot Agent into the list of boot devices. When the Boot Agent is ahead of any other bootable device in the list, it executes and tries to boot the computer over the network.
To prevent the Boot Agent from executing, enter your systems BIOS configuration and find the boot device order settings. Move the boot agent down the list after the hard drive or the device you prefer to boot from.
Intel® Boot Agent settings
Intel® Boot Agent initializes during the system startup, even if it is not the first boot device. Once the initialization screen displays, press Control-S to configure the Boot Agent settings.
Intel® Boot Agent is enabled by default on desktop adapters and disabled by default on server adapters. For server adapters, use the BOOTUTIL utility with the command-line BOOTUTIL -FE to enable Intel® Boot Agent.
If you are not booting from the network, disable Intel® Boot Agent to speed up booting your computer.
Intel® Ethernet Connections Boot Utility includes the Intel® Boot Agent User Guide and BOOTUTIL.
