This will look very similar to this question: Is it possible to recover a computer from a failed BIOS update?
Someone posted an answer just as I suspected — that it was indeed possible to connect directly to the BIOS and flash it from another computer.
I currently have a Compaq Presario SR1834NX with an ASUS A8AE-LE motherboard. It was handed to me by my brother's in-law. After all my messing around, I determined a corrupted BIOS. Running on its bare essentials (Memory, CPU, Integrated Video) it still hangs at the Compaq splash screen. It just seems to freeze and the keyboard does nothing. I tested the RAM and used a known good PSU. All that remains is the motherboard.
I looked at this motherboard for a similar sight. This is what I found (where it says COM1). Perhaps this is the connection I need to flash the BIOS?
I assume I use a similar cable as the previous superuser answer. I just need guidance on how to wire/which wires are the correct ones.
Oh and before, I already tried recovery methods (putting the ROM on a floppy did not work, and hot flashing is not an option). Simply put, this is pretty much my last option. It's not a huge deal I save this computer. Now it's more of a personal challenge to fix it. That's my primary driving force.
