How to Make a Persistent Change to Boot Order

To make a persistent change to the boot order, modify the order of devices in the BOOT_DEVICE_PRIORITY section of the XML file.

The following example shows an XML file from a Sun Blade X6275 server module (which has a built-in bootable InfiniBand interface) set to optimal defaults with a 1-GByte USB flash, a USB CD, and a dual Gig-Ethernet Express Module plugged in.

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

   biosconfig -get_boot_order filename.xml

   The following is an example of the output of the XML file:

   <?xml version="1.0" encoding="UTF-8"?>
   <BIOSCONFIG>
      <BIOSCONFIG_VERSION>2.1</BIOSCONFIG_VERSION>
      <SPEC_VERSION>2.4</SPEC_VERSION>
      <SP_NETWORK_CONFIG>
         <DISCOVERY></DISCOVERY>
         <IP></IP>
         <NETMASK></NETMASK>
         <GATEWAY></GATEWAY>
      </SP_NETWORK_CONFIG>
      <PASSWORD_CONFIG>
         <PASSWORD></PASSWORD>
      </PASSWORD_CONFIG>
      <BOOT_ORDER_OVERRIDE>
         <HELP_STRING>FIRST=Choose one of: pxe, cdrom, disk,
   floppy, bios, none</HELP_STRING>
         <FIRST></FIRST>
         <HELP_STRING>CLEAR_CMOS=Choose Yes, No or leave it
   empty, .....</HELP_STRING>
         <CLEAR_CMOS></CLEAR_CMOS>
      </BOOT_ORDER_OVERRIDE>
      <BOOT_DEVICE_PRIORITY>
      <Boot_Device_01>
         <DEVICE_NAME>USB:Port1:Memorex DVD+-RAM 510L v1</DEVICE_NAME>
      </Boot_Device_01>
      <Boot_Device_02>
         <DEVICE_NAME>SATA:3M-MRVLRD 200254-01SUN24G 0801</DEVICE_NAME>
      </Boot_Device_02>
      <Boot_Device_03>
         <DEVICE_NAME>USB:Port0:SanDisk Cruzer Contour</DEVICE_NAME>
      </Boot_Device_03>
      <Boot_Device_04>
         <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_04>
      <Boot_Device_05>
         <DEVICE_NAME>PXE:IBA GE Slot 00C8 v1324</DEVICE_NAME>
         <PCI-B-D-F>00,19,00</PCI-B-D-F>
      </Boot_Device_05>
      </BOOT_DEVICE_PRIORITY>
   </BIOSCONFIG>

2. Edit the device names displayed between the <DEVICE_NAME> tags so that the devices are listed in the desired boot order.
3. Set the boot order with the following command:

   biosconfig -set_boot_order filename.xml
