NAME

6       intel-microcode2ucode  -  convert  Intel  microcode.dat file into ucode
7       files
8

SYNOPSIS

10       intel-microcode2ucode [MICROCODE_FILE]
11

DESCRIPTION

13       intel-microcode2ucode parses Intel microcode combined  text  data  file
14       (which  usually  has  name microcode.dat) and splits it into individual
15       binary microcode files that can be loaded by the Linux kernel.
16
17       Generated microcode files are placed into intel-ucode directory,  which
18       is  created in the current working directory, and have file name format
19       of FF-MM-SS, where FF is the CPU family number, MM is the model number,
20       and SS is stepping.  All three values are zero-filled to two digits and
21       are hexadecimal (letters are in the lower case).
22
23       This tool is mostly of  historic  interest,  as  Intel  ships  separate
24       microcode files now.
