INTEL-MICROCODE2UCODE(8)             System Manager's Manual             INTEL-MICROCODE2UCODE(8)



NAME
       intel-microcode2ucode - convert Intel microcode.dat file into ucode files

SYNOPSIS
       intel-microcode2ucode [MICROCODE_FILE]

DESCRIPTION
       intel-microcode2ucode  parses  Intel  microcode combined text data file (which usually has
       name microcode.dat) and splits it into individual  binary  microcode  files  that  can  be
       loaded by the Linux kernel.

       Generated  microcode  files are placed into intel-ucode directory, which is created in the
       current working directory, and have file name format of FF-MM-SS, where FF is the CPU fam-
       ily  number, MM is the model number, and SS is stepping.  All three values are zero-filled
       to two digits and are hexadecimal (letters are in the lower case).

       This tool is mostly of historic interest, as Intel ships separate microcode files now.

OPTIONS
       MICROCODE_FILE
              Path to the microcode.dat file.  If no path has been  provided,  the  default  path
              /lib/firmware/microcode.dat  is  used.   If - (single dash) is provided as an argu-
              ment, data is read from the standard input.

EXIT STATUS
       0      Success.

       1      Error occurred: temporary buffer cannot be allocated, input microcode  file  cannot
              be  opened,  microcode  version and/or format are unknown, cannot open output file,
              cannot write to the output file.
