    Hello,
    I updated the IOS on my catalyst 3750.
    I had 12.1.11-AX and I upgraded to 12.1.19-EA1a

    but looking at boot message I see this:

    ROM: Bootstrap program is C3750 boot loader
    BOOTLDR: C3750 Boot Loader (C3750-HBOOT-M) Version 12.1(11r)AX, RELEASE SOFTWARE
    (fc1)

    so looks like the boot loader is still the old one even if the os image
    is the new one.
    Anyone knows how to upgrade the boot loader or I Can safely continue
    using it with newer OS images ?

    thanks

    Rick

    Don't worry - the boot-loader is only used for
    certain maintenance-operations [such as helping
    out when you are loading new versions of IOS];
    it plays no real part in the operation of the
    router once it has loaded IOS proper.
