AMIBIOS Setup 15-21
15.04.5 PCI/PnP SETUP
This part of the setup sets PCI and the Plug and Play related options.
Whenever you are not sure about a certain setting, you may refer to the list of default
values. The list of defaults is provided in the event that a value has been changed and
you wish to set this option to its original value. Loading the Optimal or Fail-Safe
defaults will affect all the options and will reset options previously altered.
The Fail-Safe default settings consist of the safest set of parameters. Use them if the
system is behaving erratically. They should always work but do not provide optimal
system performance.
The Optimal default values provide optimum performance settings for all devices and
system features.
The scroll list displays these options:
