Does the P5B Deluxe need a CPU connected to POST?

[Drayvn]

From what the tech said at Overclockers said, it needs the CPU to post, which is a first for me as i thought it didnt need the CPU for posting. And he answered me quite quickly so i don't know if he knew what he was talking about.

So can anyone confirm if the ASUS P5B Deluxe needs a CPU to POST?

Just download the manual. If it has a beep code for "No CPU" then it will probably beep.

Wait, you mean to say you have booted PC's without a processor and it took you to a bios screen? I'm no engineer but I don't think thats possible with any PC. Maybe i've seen a PC post without memory in it, but i'm doubting that. Reguardless, it's going to start, display nothing on the screen and start beeping like a mad man.

Anyway my final answer is no, you need a processor to handle instructions and computations. The bios can't run itself, it's just EEPROM.

On every PC I've ever seen, the CPU is needed for POST. Some PCs might be able to at least show the BIOS screen without RAM installed, but that's unlikely for most.

BIOS is nothing but software. Without the CPU there's nothing to even run the POST tests. No motherboard can do anything but maybe light up a power LED without a CPU plugged in.

superunknown is right, POST without a CPU is impossible.
