Specifying the Startup System Image

You can enter multiple boot commands in the startup configuration file or in the BOOT environment
variable to provide backup methods for loading a system image.
The BOOT environment variable is also described in the "Specify the Startup System Image in the
Configuration File" section in the "Loading and Maintaining System Images and Microcode" chapter of
the Cisco IOS Configuration Fundamentals Configuration Guide.
Use the following sections to configure your switch to boot from flash memory. Flash memory can be
either single in-line memory modules (SIMMs) or flash disks. Check the appropriate hardware
installation and maintenance guide for information about types of flash memory.
