Hints:
- Option "UseBIOS" must be set to Yes in xorg.conf
- Do not enable the ACPI module 'processor', else you will hear a continuous noise from the motherboard.
- If you have the original 20GB 4200rpm IBM Travelstar disk and its constant loud noise level bothers you, replace it with a newer model. The above 40GB 5400rpm disk has no sound at all!
