Abstract
Example embodiments disclosed herein relate to altered option read-only memory. A copy of an option read-only memory is stored. The copy is used during a boot process based on a determination that the option read-only memory has been altered.
Claims14
A method comprising:
- saving, for a device, a backup copy of option read only memory of an adapter card to storage;
- booting the device via a subsequent boot process;
- loading the backup copy during the subsequent boot process based on a determination that the option read only memory has been altered;
- prompting a user of the device to indicate whether the alteration to the option read only memory is intentional;
- and
- receiving an indication as to whether the alteration was intentional.
3 more elements
A computing device comprising:
- a non-volatile memory;
- a backup module to cause storage of backup data of an option read only memory of an adapter card at a storage location of the nonvolatile memory;
- a boot module to:
- determine that other data subsequently stored at the option read only memory does not match the backup data stored at the storage location;
- and
- initialize the adapter card using the backup data based, at least in part, on the determination;
- a presentation module to present a notification that the subsequently stored data does not match the backup data;
- and
- a management module to receive an indication as to whether the change in the subsequently stored data was intentional.
6 more elements
A non-transitory machine-readable, storage medium storing instructions that, if executed by a processor of a device, cause the processor to:
- save a copy of data of an option read only memory of an adapter card;
- boot the device via a boot process;
- during the boot process, read the option read only memory to retrieve subsequent data;
- determine that the subsequent data is different from the copied data;
- use the copied data to initialize the adapter card based on the determination;
- cause presentation indicating that the option read only memory has been modified during the boot process;
- prompt a user to indicate whether the modification was intentional;
- and
- receive a response as to whether the alteration was intentional.
