Hi
Need your bios dump ONLY

Hello,

Also have a Legion Y520-15IKBN, and I'd like to disable whitelists for SSD and wifi cards + get access to advanced options (would appreciate to change the fan temperature threshold/speed).

I just received a SPI programmer and SOIC8 clip. Could somebody kindly send me a link to a guide explaining how to get a BIOS dump with it ?

[Chiptune]

P.S. there are no whitelists on your laptop

Good to know ! Anyway I mostly wanted to enable advanced options
Thank you for your quick reply. Will send you the dump in a minute.
