Problems Caused by the BIOS Option "PnP OS"
Support knowledgebase (intnull)
Applies to
SuSE Linux: All versions
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:
- some "onboard" components
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. Among other sources, more information about the
BIOS can be found at www.sysopt.com.
