Hello All,

I made a mistake when recovering from a broken bios chip. I followed the instructions from page 1 and didn't realize it's a different EMC number. Mine is a 2925 and the one I put on was for a 2632. So I'm assuming that's why I'm getting a black screen. Is the EMC number something I need to change in the hex editor and reflash or is it completely different? I already followed the guide to put in my SN and fix the checksum.

Looks like the bios chip I have is larger? There is extra space compared to what you sent. Will the mac still read it right or do I need a different chip.

no the chip is bigger, the contents of the chip are longer than normal....I think you copied it with errors...write the bios from the post above on the original chip...
