My name is Randy,
I will be glad to assist you with this.
Is there a part number on the board?
Hi, are you trying to remove an EFI password?
If so, this video should give you an idea of where the eeprom is.https://www.youtube.com/watch?v=-i2pNQUx33E
Do you have the system apart? Can you take a high res photo of the various sections of the board?
If you no longer wish to continue with your question, you can request a refund at any time by contacting***@******.***
What about the underside of the board?
look on the underside of the logic board for a chip that says "MX25L6473E" on it.
Otherwise look for a Windbond 25064FVIQ.In the following pic, it should be the one outlined in light blue...https://d3nevzfk7ii3be.cloudfront.net/igi/6vjM32B2PHbVd2AJ.huge

And what I mean by "light blue" above I'm talking about the chip that's below the red and the yellow... not the aqua outlined one to the left.
