Sorry to be such a noob but I have done a lot of searching and can't find the answer to this. This was my first mod attempt and it went pretty good. Took me 2 times to get it working alright before I got to the bios. I am able to press the power button fine to boot up with the chip enabled and I am able to boot with the chip off in MS. But I can't boot with the backup flash by holding down the power and eject buttons. I just want to make sure I am not missing something before I proceed.
