5.2.4 Enabling Option ROM scan
In order to configure an expansion card that has been installed or replaced, the
card’s Option ROM has to be enabled in the system board BIOS. The card’s
firmware is called by the system BIOS upon reboot and can be entered and
configured.
Option ROM can be enabled permanently (e.g. in case of a boot controller that
may require frequent setup) or temporarily for one-time configuration. When
permanently enabling a controllers’s Option ROM, keep in mind that only two
Option ROMs can be activated in the system board BIOS at a time.
Ê Enter the BIOS.
Ê From the Advanced menu select Option ROM Configuration.
Ê Identify the desired PCI slot and set its Launch Slot # OpROM setting to
Enabled.
Ê Save your changes and exit the BIOS.
I Up to two Option ROMs can be activated in the system board BIOS
at a time.
For detailed information on how to access the BIOS and modify
settings, refer to corresponding BIOS Setup Utility reference manual.
When the enabled expansion card is initialized during the POST phase of the
boot sequence, a key combination is displayed temporarily to enter the
expansion card’s firmware.
Ê Press the displayed key combination.
Ê Modify the expansion card firmware options as desired.
Ê Save your changes and exit the firmware.
I The expansion card’s option ROM can now be disabled in the system
board BIOS.
Exception: If the expansion card controls a permanent boot device, the
card’s Option ROM has to remain enabled.
