    Hi everyone,

    Can anyone tell me what is the difference between bootflash image and bootldr image.Any help is highly appreciated.Thanks in advance for your reply.

    I have one more query like just have a look to the flollowing:
    Millennium#sh bootvar
    BOOT variable = slot1:rsp-pv-mz.122-46.bin,1;
    CONFIG_FILE variable does not exist
    BOOTLDR variable = bootflash:rsp-boot-mz.122-46.bin
    INHIBIT_BSI variable does not exist
    Configuration register is 0x2102

    Slave auto-sync config mode is on

    Current slave is in slot 7.
    slave BOOT variable = slot1:rsp-pv-mz.122-46.bin,1;
    slave CONFIG_FILE variable =
    slave BOOTLDR variable = bootflash:rsp-boot-mz.122-46.bin
    slave Configuration register is 0x2102
    Millennium#sh flash
    -#- ED ----type---- --crc--- -seek-- nlen -length- ---------date/time--------- name
    1 .. image 55E6C36C 709504 22 7246980 Aug 5 2006 11:09:57 +05:30 rsp-boot-mz.122-37.bin

    In the above 2 commands it shows the ios image.In this the image which is displayed in the first command is the image which is used to boot to rommon.Is it true.Let me know if it is wrong.In the second command it displays there are 2 images in flash memory,if i want to make the router to boot from second image what command i should use.Plz reply to this at the earliest.Thanks in advance for your reply.

    Re: Boot Image

    And you didn't query google again??
    Is the google blocked on your location??

    oh well, in short:
    the system flash bootflash is the actual software running on the switch.
    the boot loader is the software that boots the system software or the boot helper.

        You can find it out which file he is booting with the show version command.

        he is either booting from one of this:

        BOOT variable = slot1:rsp-pv-mz.122-46.bin,1;
        BOOTLDR variable = bootflash:rsp-boot-mz.122-46.bin


        bootflash: This device is the internal flash memory.
        slot0: This device is the first PCMCIA slot on the route processor card.
        slot1: This device is the second PCMCIA slot on the route processor card.
