Hello, I'm from Mexico, I'm 46 years old, I started using computers since I was 8 years old (mostly for games on a C64) which was uncommon back in those days specially in Mexico, I started earning some money in High school by building and fixing desktop computers, unsurprisingly I work in tech support. I just recently purchased a broken Acer Nitro 5 for 100$ to rebuild it and I have it kind of working now, but I'm experiencing some issues with the KBC/BIOS image, searching for a solution I found this forum, so here I am and I hope I can get some help and contribute back to others.Comment

Hey guys, I'm Frosticcraft.
Just popped on this forum to learn about BIOS flashing and whatnot. I'm a complete noob, but would love to learn. Lenovo sucks and doesn't supply BIN BIOS files and I found this place looking for one. Anyways, wish me luck! hahaComment
