Hi Klem,
I have read some random pages on this thread and I'm very impressed how long you've been helping people here to mod their BIOS. It's incredible! Congratulations for the work, seriously!
I took a time to look at the site you suggested to work on the BIOS change and it's very low level as far as I could understand.
So as I could not have a good understanding on that and try to do the mod by myself, I would like to ask you that favour. My Y50-70 BIOS is very old and seems very limited, so I wanted to unlock all the capabiities possible on the BIOS for it. It would include hidden menus, white list WLAN, etc.
If you can do that, I will be extremely glad. Thanks is advance. I have just sent the backup results via PM.
