Hello. I like computers since my first one, one with 4MHz Cpu, 128KB Ram, with Basic and Assambler on it. I like to fix them and I like learning new stuff. Now I am learning to read/write BIOS chips. My laptop has a bad ram soldered on it an and this is a great opportunity for learning new stuff.Comment
