Notes . . .
1. Never disable OPROM for the mezzanine slot if the mezzanine card is present, or the system will not boot. If
you remove the mezzanine card and disable its OPROM, you can boot from another bootable device (RAID card,
embedded RAID, or from SAN via an HBA or CNA card). When you boot from a device, make sure its OPROM is
enabled, it is in the proper boot sequence, and its BIOS is configured for a bootable device.

2. If you want to boot from a device other than the 9271-8i, or 9271CV-8i MegaRAID PCIe card, you can leave the
card installed. Just disable the OPROM for its slot, and the system will boot even with the card installed.

4. External RAID card is the 9285CV-8e or 9286CV-8e. Any of these can be installed simultaneously with one
mezzanine RAID controller card. They cannot be used simultaneously with an internal RAID controller card
(9271-8i, or 9271CV-8i) because of mounting space limitations for the supercap (there is space to mount only
one supercap).
