Notes . . .
1. If you want to boot from a device other than the 9270CV-8i, 9240-8i, or 9220-8i MegaRAID PCIe cards, you can
leave the cards installed. Just disable the OPROM for their slots, and the system will boot even with the cards
installed.

must go into the BIOS and enable the OPROM for the desired slot and disable the OPROM for the default PCIe
slot (see Figure 8 on page 56).
