/*
|
||||
* Convert Intel microcode.dat into individual ucode files
|
||||
* named: intel-ucode/$family-$model-$stepping
|
||||
*
|
||||
* The subdir intel-ucode/ is created in the current working
|
||||
* directory. We get multiple ucodes in the same file, so they
|
||||
* are appended to an existing file. Make sure the directory
|
||||
* is empty before every run of the converter.
