I'm a software engineering (college) student, and my school laptop (Z50-70) is out of commission. I really need my laptop back up and running soon for school, so I appreciate any help you can provide. Thanks in advance!
Background
Due to a known bug in Ubuntu 17.10, my BIOS was corrupted, and changes are not saved. My HDD was formatted, and since BIOS changes cannot be saved, I cannot change the boot order to boot using another device. I have ordered a CH341A based programmer and a test clip similar to those mentioned on a thread here on bios-mods. (Source 1 below)
I've been searching for clear instructions on how to proceed, but I'm having troubles with that. I can extract the .exe BIOS update from Lenovo to get a .fd file, but I believe I need a .bin file to flash the chip. I was able to find someone in the same situation as me on the Ubuntu bug report page. (Source 2 below)
Questions
1) Where do I get a .bin file to flash the chip with?
2) Do I need to read my chip and modify the current BIOS, or can I simply use a .bin found online?
3) What did the individual from the bug report comment (Source 2 below) mean about the different regions or the ROM?
4) What software should I use? E.g. software to read, write, and edit the ROM data.
