unset Appendix A Cisco Catalyst Switch 3020 for HP Boot Loader Commands unset Use the unset boot loader command to reset one or more environment variables. unset variable ... Syntax Description variable Use one of these keywords for variable: MANUAL_BOOT-Decides whether the switch automatically or manually boots. BOOT-Resets the list of executable files to try to load and execute when automatically booting. If the BOOT environment variable is not set, the system attempts to load and execute the first executable image it can find by using a recursive, depth-first search through the flash file system. If the BOOT variable is set but the specified images cannot be loaded, the system attempts to boot the first bootable file that it can find in the flash file system. ENABLE_BREAK-Decides whether the automatic boot process can be interrupted by using the Break key on the console after the flash file system has been initialized. HELPER-A semicolon-separated list of loadable files to dynamically load during the boot loader initialization. Helper files extend or patch the functionality of the boot loader. PS1-A string that is used as the command-line prompt in boot loader mode. CONFIG_FILE-Resets the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration. BAUD-Resets the rate in bits per second (bps) used for the console. The Cisco IOS software inherits the baud rate setting from the boot loader and continues to use this value unless the configuration file specifies another setting. BOOTHLPR-Resets the name of the Cisco IOS helper image that is first loaded into memory so that it can then load a second Cisco IOS image into memory and launch it. This variable is used only for internal development and testing. HELPER_CONFIG_FILE-Resets the name of the configuration file to be used by the Cisco IOS helper image. If this is not set, the file specified by the CONFIG_FILE environment variable is used by all versions of Cisco IOS that are loaded, including the helper image. This variable is used only for internal development and testing. Command Modes Boot loader Command History Release 12.2(25)SEF Modification This command was introduced.
