SDB:Problems Caused by the BIOS Option "PnP OS"

Şuraya atla: kullan, ara


Symptom:

The installation progress or the boot sequence of an installed system fails and you receive an error message. Although the symptom can be assigned to a typical error message, experience shows that the cause can often be found in the BIOS option "Plug & Play Operating System ". The description of the option may also be used in the form of "PnP OS" or "PnP Aware O/S".

Cause:

If the option is set to "Yes", the allocation of your machine's resources (IO Ports, IRQs, and DMAs) will be handled by the operating system. If the option is set to "No", the allocation of the resources will be handled by the BIOS. The setting must be set to "No" to run a Linux system, otherwise you might get in trouble with the following components:

  • ISA Devices
  • PCI Devices
  • some "onboard" components
  • USB Devices

Solution:

Set the option to "No" if your BIOS offers an option like "PnP OS". (Attention: Sometimes the option is referred to as "Non PnP OS". In this case, it means the contrary and the option must be set to "yes"!). If additionally the option "Reset Configuration Data" or "Update ESCD" is offered, set it to "yes" or alternatively to "enabled".


Our support team could not offer further help to configure your BIOS, because the descriptions often differ and are located in various menus. Consult the documentation of the motherboard manufacturer.
