BootROM Menu

BootROM Menu

The Boot Read-Only Memory (BootROM) is a set of programs fixed in the read-only memory (ROM) chip on a device's main card. The BootROM contains the basic input/output program, system settings, power on self-test (POST) program, and system self-startup program.

The BootROM is classified into the basic BootROM and extended BootROM. The basic BootROM provides simple functions for loading and upgrading the extended BootROM. The extended BootROM is also called BootLoad and provides a variety of functions such as system software loading, file management, and device installation and commissioning. The extended BootROM program provides a series of BootROM menus (also called BootLoad menus). You can press Ctrl+B to enter a BootROM menu when the device starts. The BootROM menus support various operations, such as transferring files, setting the startup file, and modifying the BootROM and console port passwords.

If the device properly starts, accessing the BootROM menu is not necessary. If either of the following situations occurs, you can use the BootROM menu to:
  • Restore or upgrade the system when the system stops responding and the command line interface (CLI) cannot be displayed.
  • Delete the password for logging in to the device using the console port when you forget the password.

The BootROM menu also allows you to back up the configuration file and change the BootROM password.

  • To view the device startup process, log in to the device using the console port. Press shortcut keys as prompted to access a BootROM menu. For the method of login using the console port, see Configuring Login Through a Console Port.

  • Do not power off the device while managing the device using the BootROM; otherwise, the settings in the BootROM menu are lost.
  • The screen display information varies depending on devices.
