I've recently inherited an old HP M7000, and decided to make a headless server out of it. My only problem is, that the included motherboard (Asus P5LP-LE) does not have an integrated graphics card, and the only one at my disposal is a bit too powerful to be in a server (Radeon HD3870).
Given that I want to make it use the least possible power, I want to get rid of the graphics card, but any time I try, the computer won't boot, and I found no option to disable this behavior. Does anyone know a way to bypass this error some way? I would prefer an answer not beginning, ending with, or containing "buy a cheap graphics card"!
