Configuration Utilities for Add-In Cards
The method for interacting with configuration utilities for add-in cards and (system resident) I/
O adapters differs depending on whether Legacy BIOS Boot Mode or UEFI BIOS Boot Mode
is used.
In Legacy BIOS Boot Mode, I/O adapter utilities are invoked during BIOS POST progression
using hot keys identified by the adapter Option ROM during POST. When the hot key is
pressed, the adapter specific configuration utility interface is presented. Often the interface will
have a vendor-specific design.
In UEFI BIOS Boot Mode, the configuration screens for the add-in cards will appear as menu
items in the BIOS Advanced Menu as part of the standard BIOS Setup Utility screens. For
example, if the Oracle Storage 12 Gb/s SAS PCIe RAID host bus adapter is installed in the
server, the configuration utility for the HBA appears as a menu selection under the iSCSI menu
option on the BIOS Advanced Menu.
