Available Software Release Packages
In Legacy BIOS boot mode, PC architecture constraints are placed on Legacy Option ROM allocation. These constraints are not placed on UEFI Option ROMs, which are commonly referred to as UEFI drivers.
The system BIOS allocates 128 Kbytes of address space for Option ROMs. This address space is shared between on-board devices and PCIe plug-in cards. This fixed address space limitation is imposed by the PC architecture and not by the BIOS itself. You can to exhaust the available address space when installing PCIe plug-in cards. When the address space is exhausted, the BIOS displays an Option ROM Space Exhausted message, which means that one or more devices cannot load Option ROMs.
For example, if you install a SCSI PCIe card, you might encounter the following message in Oracle ILOM event log:
Option ROM Space Exhausted - Device XXX Disabled
By default, all on-board Options ROMs are enabled in the BIOS. However, you can disable most of these Option ROMs, unless they are required to support booting from the associated device or to provide some other boot-time function. For example, it is not necessary to load the Option ROM for the on-board network ports unless you mean to boot from one or more network ports (even then, you can disable the Options ROMs for the remaining ports).
To minimize server boot time and reduce the likelihood of exhausting the available Option ROM address space, disable the Option ROMs for all devices that you do not intend to boot from. Enable Option ROMs only for those devices from which you intend to boot.
If you encounter the Option ROM space exhausted condition even after disabling all devices you do not intend to boot from, then disable additional Option ROMs. Under some circumstances it might be necessary to disable Option ROMs for all devices except for the primary boot device.
