a multinode configuration
You can use the Configuration Setup utility program to change the sequence and
have the server scan one of the first six PCIe slots before it scans the integrated
devices. Press F1 when prompted during system POST. In the Start Options
panel, set the PCI Device Boot Priority to the slot you want to boot from as
shown in Figure 3-78. The default is Planar SAS.

Note: If you want to change this setting on secondary nodes in a multinode
configuration, you should first boot to stand-alone (non-merged) and then
make the necessary changes. Once you have complete the changes, you can
then reemerge the multinode configuration.
3.5.3 PCI adapter installation order
We recommend that you install the adapters in a specific add-in order to balance

The recommended order for PCIe adapter installation is:
1. Slot 1
2. Slot 5
3. Slot 2
4. Slot 6
5. Slot 3
