DLMICROCODE(8)                                     DLMICROCODE(8)

     NAME
          dlmicrocode - update drive microcode

     SYNOPSIS
          disk/dlmicrocode -f fw disk ...

     DESCRIPTION
          Dlmicrocode uses standard SCSI or ATA commands to update a
          drive's microcode with a new firmware blob specified with
          the -f flag.  Firmware is drive and model specific, and
          there is no guarantee that a drive will implement sufficient
          checking.  Be careful!

     EXAMPLE
                    disk/dlmicrocode -f fw /dev/sdE0 /dev/sdE1

     SEE ALSO
          sd(3), atazz(8).

     BUGS
          Bricks are possible.  Data loss is possible.  Firmware
          update is often not implemented robustly, and even if they
          work, your data may be gone.
