 Hi all. I'm Orange, 21 years old, and a student of Computing and IT. I end up collecting a lot of 'borked', but otherwise working tech, and it's normally caused by software. So far, I've managed to get stuff working properly again by doing surface level software or hardware repairs (think of stuff along the lines of reinstalling Windows or replacing RAM), but I'm out of my league when it comes to BIOSes and UEFI, hence I signed up for this forum which seems to have a relatively active community for it. Hope to learn a lot from this forum's posts, and resolve some issues I've been having.Comment

 Hi, I'm ZeeroMX, I'm 52 years old, I was here before when I successfully flashed the BIOS of a Lenovo E41 in 2018 (what a coincidence), I just caught another Lenovo which doesn't post, I work in IT but really with servers, storage and switches, working with electronics is more like a hobby to me, will try to stay around this time and be more helpful to others.Comment

 Hey y'all, I'm just occasionally poking around in stuff to fix or figure out, ideally without releasing the magic smoke, and this looks like a fun place to find info old and new alike. Cheers!Comment
