    Hello there.
    I bought new 8MB flash memory for Cisco 2501 router.
    I had old one 8MB flash already.

    I have use a IOS image 12.1(26).
    I did remove old one and replace with new one.
    Whenever I copy IOS image to new one this below error occured.

    %Error: System flash location 0x3100000 - wrote 0xF9 , read 0xFF
    COPY: Text checksum verification failure
    TFTP from failed/aborted
    Verifying checksum... invalid (expected 0xE4, computed 0x4307)
    %Error: System flash location 0x3100000 - wrote 0x1E , read 0x18

    So, I did replace with old one again do same thing.
    This is success. IOS image copied to old flash as nomal.
    Is this new memory has somethinn wrong?
