A binary representation of the UEFI variable store. Only non-volatile variables are stored. This is a base64 encoded and zlib compressed binary value that must be properly encoded.
When you use register-image
to create an AMI, you can create an exact copy of your variable store by passing the
UEFI data in the
UefiData parameter. You can modify the UEFI data by
using the python-uefivars tool
on GitHub. You can use the tool to convert the UEFI data into a human-readable format
(JSON), which you can inspect and modify, and then convert back into the binary format
to use with register-image.
For more information, see UEFI Secure Boot in the Amazon EC2 User Guide.
