How to Change Boot Order Based on the PCI Bus, Device, or Function

The biosconfig command can alter the boot order based on the PCI bus, device, or function if the boot order list contains that information.

1. Create an XML file containing the current boot order of your system with the following command:

   biosconfig -get_boot_order filename.xml

2. Edit the devices listed between the <PCI-B-D-F> tags so that they are in the desired order.

   For example:

   <BOOT_DEVICE_PRIORITY>
   <Boot_Device_01>
   <DEVICE_NAME>PXE:IBA GE Slot 00C8 v1324</DEVICE_NAME>
   <PCI-B-D-F>00,19,00</PCI-B-D-F>
   </Boot_Device_01>
   <Boot_Device_02>
   <DEVICE_NAME>IB:Slot2.F0:PXE:MLNX HCA IB 1.9.972 (PCI 07:00.
   </DEVICE_NAME>
   <PCI-B-D-F>07,00,00</PCI-B-D-F>
   </Boot_Device_02>
   <Boot_Device_03>
   <DEVICE_NAME>USB:Port1:Memorex DVD+-RAM 510L v1</DEVICE_NAME>
   </Boot_Device_03>
   <Boot_Device_04>
   <DEVICE_NAME>USB:Port0:SanDisk Cruzer Contour</DEVICE_NAME>
   </Boot_Device_04>
   <Boot_Device_05>
   <DEVICE_NAME>SATA:3M-MRVLRD 200254-01SUN24G 0801</DEVICE_NAME>
   </Boot_Device_05>
   </BOOT_DEVICE_PRIORITY>

3. Set the boot order with the following command:

   biosconfig -set_boot_order filename.xml
