Hi to all. I own a Acer Aspire 1551. In bios (Phoenix) of my laptop has a hidden menu (Advanced). By WinHex I found the transition to the processing function "Advanced " menu. I tried to unhide it, but I have a problem with assembler. please help me find the value in nvram

This is the code that I found in TEMPLAT00.ROM. What should I do next? Sorry for my english, I'm from Russia. :)

Code: Select all
