I'm new on this forum and I'm so newbie in bios modding (Sorry, my english is poor ). I have a samsung laptop (Samsung NP-RV419-CD1BR) and I want to change my CPU. This laptop have a celeron b800 (sandy bridge, rPGA989) and I need to upgrade this CPU to i5 3210m (ivy bridge). I searched here on the forum and tried to follow some guides, but I wasn't successful when trying to do microcode update.
