TechNote: Asus P5QL slow startup

Small note to anyone with a Asus P5QL based computer (and possibly other Asus boards as well). If your machine is running unusually slowly during BIOS boot, plug your keyboard and mouse to a different USB port. The wankers at ASUS have mapped part of the USB ports to IRQs that overlap the SATA controller, causing IRQ conflicts, which in turn wrecks your machine. In case of the P5QL Pro board, the two ports you must not use are the ones next to the ethernet port. Freakishly bad engineering, I must say.
