Methods and apparatus to perform an enhanced S3 protocol to update firmware with a boot script update
Methods, apparatus, systems, and articles of manufacture perform an enhanced S3 protocol to update firmware with a Boot Script update are disclosed. An example apparatus includes a management agent to store a firmware update into memory; and request an operating system (OS) to enter into an S3 sleep state; the OS to, in response to the request from the management agent, enter into the S3 sleep state and trigger an interrupt; and a basic input/output system (BIOS) to, in response to the interrupt from the OS update a Boot Script according to the firmware update; and wake up the OS with a wake vector.
1. An apparatus to update firmware during a sleep state, the apparatus comprising:
instructions;
at least one processor circuit to be programmed by the instructions to:
cause storage of a firmware update into memory; and
request an operating system (OS) to enter into an S3 sleep state, the request to cause the OS to trigger an interrupt; and
a basic input/output system (BIOS) to:
enter into an S3 sleep state based on the interrupt;
wake up after a preset amount of time after the OS triggers the interrupt;
while the OS is in the S3 sleep state, update a Boot Script according to the firmware update, the Boot Script to be executed by the BIOS to operate the BIOS; and
wake up the OS with a wake vector.
2. The apparatus of claim 1 , wherein the BIOS is to process the firmware update to determine that the update is at least one of authentic or relevant to the BIOS.
3. The apparatus of claim 1 , wherein the instructions are first instructions, and the firmware update includes second instructions to update a previous Boot Script implemented by the BIOS.
4. The apparatus of claim 3 , wherein the BIOS is to execute the second instructions to update the previous Boot Script implemented by the BIOS.
5. The apparatus of claim 1 , wherein the BIOS is to extract code from a binary image included in a firmware update capsule.
6. The apparatus of claim 5 , wherein the BIOS is to execute the extracted code to update the Boot Script.
7. The apparatus of claim 1 , wherein the BIOS includes:
Boot Script update instructions to update the Boot Script according to the firmware update; and
Boot Script execution instructions to cause execution of the updated Boot Script.
8. The apparatus of claim 1 , wherein the instructions are first instructions, and the firmware update includes at least one of second instructions to update a Boot Script previously implemented by the BIOS or executable code to be executed by the BIOS.
9. A non-transitory computer readable storage medium comprising instructions to cause at least one processor circuit to at least:
cause storage of a firmware update into memory;
request an operating system (OS) and a basic input/output system (BIOS) to enter into an S3 sleep state;
wake up the BIOS after a preset amount of time after the OS triggers an interrupt;
while the OS is in the S3 sleep state, update a Boot Script according to the firmware update, the Boot Script executed by the BIOS; and
wake up the OS with a wake vector.
10. The computer readable storage medium of claim 9 , wherein the instructions cause one or more of the at least one processor circuit to process the firmware update to determine that the update is at least one of authentic or relevant.
11. The computer readable storage medium of claim 9 , wherein the firmware update includes second instructions to update a previous Boot Script.
12. The computer readable storage medium of claim 11 , wherein the instructions cause one or more of the at least one processor circuit to update the previous Boot Script.
13. The computer readable storage medium of claim 9 , wherein the instructions cause one or more of the at least one processor circuit to extract code from an image of the firmware update.
14. The computer readable storage medium of claim 13 , wherein the instructions cause one or more of the at least one processor circuit to execute the extracted code.
15. The computer readable storage medium of claim 9 , wherein the firmware update includes at least one of second instructions to update a Boot Script previously implemented by the BIOS or executable code to be executed by the BIOS.
16. A method to update firmware during a sleep state, the method comprising:
storing a firmware update into memory;
requesting an operating system (OS) and a basic input/output system (BIOS) to enter into an S3 sleep state;
waking up the BIOS after a preset amount of time after the OS triggers an interrupt;
while the OS is in the S3 sleep state, updating a Boot Script according to the firmware update, the Boot Script executed by the BIOS; and
waking up the OS with a wake vector.
17. The method of claim 16 , including determining that the update is at least one of authentic or relevant to the BIOS.
18. The method of claim 16 , including updating a previous Boot Script implemented by the BIOS.
19. The method of claim 18 , including executing instructions to update firmware.
20. The method of claim 16 , including:
extracting code from an image of the firmware update; and
executing the extracted code.
