verifying an e3 NOR dump

hi im new to the forums and new to modifying the ps3. i have a e3 flasher installed on a ps3 slim and i have been following the scene since geohots 3.55 jailbreak.

Ok now down to my question.

would anybody be able to link me to or create an in depth tutorial for checking e3 flasher nor dumps. Or would anybody be willing to check my dump for me as i dont fully trust myself as i want to make sure this dump/backup is not a duff.

any help would me much appreciated

Thanks in advance
