I want to disable the post check beep at the boot up of the computer. I know that the simple way is to unplug the pc speaker but i want to do so. I want to know whether there is an option in bios (i know that there is) that disables it without having to unplug the speaker. What is that option called like give me a general term or menu that i can find in the bios of my computer. Moreover, i don't think it is available in my bios so do i need to upgrade bios? which arises a second question that what is the simplest way to upgrade a bios and make sure that it is properly done or pc won't boot up. Please avoid giving me links to info as i can do it myself but i want to know in simple sentences or even complicated sentences as long as it is here. Please give me the links only when you think that download a certain software might be a good idea.
