Specifications

and how the tests are performed. The nvramtool controls both the BIOS and EDA for testing. The bits are
not common across platforms and are defined in the configuration file. When using this tool, you must write
the correct bits because the tool does not know the details of the registers it is writing. The nvramtool can
display the bit-level detail in the NVRAM registers, depending on how you define it in the configuration file.
Tests
There are no tests of the NVRAM. This tool only controls the bits.
