| NBP                           | Description                                                                                                                                                                                                                                                                                                                             | Architecture/BIOS                                      |
| ----------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------ |
| PXEboot.com                   | Requires the end-user to press the F12 key for PXE boot to continue. (This is the default NBP.)                                                                                                                                                                                                                                         | x86-based and x64-based BIOS (same file used for both) |
| PXEboot.n12                   | Immediately begins PXE boot (does not require pressing F12 on the client).                                                                                                                                                                                                                                                              | x86-based and x64-based BIOS (same file used for both) |
| AbortPXE.com                  | Allows the device to immediately begin booting by using the next boot device specified in the BIOS. This allows for devices that should not be booting by using PXE to immediately begin their secondary boot process without waiting for a timeout.                                                                                    | x86-based and x64-based BIOS (same file used for both) |
| Hdlscom1.com and Hdlscom2.com | Systems that do not support firmware console redirection display the prompt "Press space or F12 for network boot" by using console redirection to serial port 1 or 2. Users can proceed with the boot process by pressing either button, or they can exit the boot process by not pressing either button.                               | x86-based and x64-based BIOS (same file used for both) |
| Hdlscom1.n12 and Hdlscom2.n12 | Systems that support firmware console redirection do not display the prompt "Press space or F12 for network boot," and they do not wait for user input.                                                                                                                                                                                 | x86-based and x64-based BIOS (same file used for both) |
| Bootmgfw.efi                  | The EFI version of PXEboot.com or PXEboot.n12 (in EFI, the choice of whether or not to PXE boot is handled within the EFI shell, and not by the NBP). Bootmgfw.efi is equivalent to combining the functionality in PXEboot.com, PXEboot.n12, abortpxe.com, and bootmgr.exe. This currently exists only for Itanium-based architectures. | x64 EFI and IA64 EFI                                   |
| wdsnbp.com                    | A special NBP developed for use by Windows Deployment Services that serves the following general purposes:Architecture detection, Pending devices scenarios, Network boot referral cases (including use of DHCP options 66 and 67)                                                                                                      | x86-based and x64-based BIOS (same file used for both) |
| Wdsmgfw.efi                   | A special NBP developed for use by Windows Deployment Services that serves the following general purposes: Handles prompting the user to press a key to continue PXE boot, Pending devices scenarios, Network boot referral cases (including use of DHCP options 66 and 67)                                                             | x64 EFI and IA64 EFI                                   |
