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

BIOSconfig also alters the boot order based on the PCI bus/device/function if the boot order list contains that information. (For example, USB devices do not have this information, but PCI devices do). For example, using biosconfig -set_boot_order with this XML input moves the specified Ethernet NIC to the top of the boot list:

• Input similar XML code:

  <BIOSCONFIG>
     <BOOT_DEVICE_PRIORITY>
     <Boot_Device_01>
        <PCI-B-D-F>00,19,00</PCI-B-D-F>
     </Boot_Device_01>
     </BOOT_DEVICE_PRIORITY>
  </BIOSCONFIG>

  • As a result, the boot list now becomes:

    <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>
