iLO5 Redfish BootMode Changes

[redfish_woes]

I am having issues trying to configure the "BootMode" from "UEFI" to "Legacy" using the Redfish API on iLO5. As I read the docs it appears that I need to use something similar to the below to make this happen. 

curl --location --request PATCH 'https://SERVER_NAME_HERE/redfish/v1/systems/1/bios/settings' \
--header 'X-Auth-Token: 7c7663bb1967996f9884dcfc73569d49' \
--header 'Content-Type: application/json' \
--data-raw '{
"BootMode": "LegacyBios"
}'

It seems to successfully apply and I get back the "MessageId": "iLO.2.14.SystemResetRequired". I can verify that the settings are in the pending queue located at

/redfish/v1/systems/1/bios/settings

If I reset the system it continues to boot in UEFI, but if I manually login to the iLO gui and change the boot mode to "Legacy Bios" it works as expected. Is this a different setting that needs to be passed in via API request to perform the same steps to force the permanent boot mode to Legacy instead of UEFI?

Any help or extra information assistance would be extremely helpful.

I have managed to figure out the issue with the disagreement between the documentation and reality. 

The json data should be this instead of what is suggested by the documentation.

curl --location --request PATCH 'https://SERVER_NAME_HERE/redfish/v1/systems/1/bios/settings' \
--header 'X-Auth-Token: 7c7663bb1967996f9884dcfc73569d49' \
--header 'Content-Type: application/json' \
--data-raw '{"Attributes": {"BootMode": "LegacyBios"}}'

This seems to be not well explained in the official API documentation. Hopefully this will help others who run into this issue.
