Switch Bootloader vs bootflash:

    On a system with 2 MSFC2s there is an option to set the image via "set
    system flash bootflash:<image name>"

    there is also a "boot bootloader" option

    I don't know the difference between the two. Some of the switches have
    both the bootflash and the bootloader statements, while others have
    only the bootflash statement.

    When I perform a "show version" on the switch that only has the
    bootflash command, the image name shows up twice.

    When I peform a "show version" on the switch that has both the
    bootflash and bootloader statements, the bootflash image shows up 1st
    and the bootloader image version shows up second.

    Can anyone explain the difference between the two and whether both are
    needed.

    Thanks

    the system flash bootflash:<image name> is the actual software running
    on the switch.

    the boot loader is the software that boots the system software or the
    boot helper.

    Running IOS on msfc2 does not require the boot helper but I think CatOS
    does.
