[REQUEST] HP DV7-2250SF: Help for remove Whitelist please

[kurtspirit]

Hello,
i try to remove the whitelist in the DV7-2250SF bios. I follow the guide and find the values : 31 00 30 00 34 00 2d 00 55 (offset @00009256ab0)  without problem, MZ too (offset @000092570c0) but i never find this part :

"8. You will notice that there is a lot of blank space around and below the 'MZ', this is header information and is of no interest. Scroll down till the ASCII pane no longer is mostly blanks, about a page, you should see «55 8b ec», this is the start of the program and is setting up the stack"

Can someone help me to find it please? 
Here is the link for the firmware : DV7-2250SF

Thank you very much
Jonathan
