i have a asus b85m-g mb from new and a intel core i5 s1150 also from new so neither have been up and working as of yet. however i think i need to update the bios to be compatible with this cpu plus as i don't have a compatible cpu with this board i can't access the bios as of yet can i still update the bios when i am unable to get a signal to monitor and have visuals. i don't have to buy a copatible lesser cpu just to update bios to then make it compatible with the higher spec cpu do i ?
