LSI SAS2FLSH Flash Firmware and BIOS Syntax

sas2flsh.exe -f 9201_16I.BIN -b mptsas2.rom

Creating the Bootable Media

  1. Download FDOEMCD, here.
  2. Download the latest (as of this writing) IT mode firmware, here. Look for the IT_FW_BIOS_for_MSDOS_Windows.zip firmware package to download.
  3. Extract FDOEMCD to its own separate directory.
  4. Copy the following files from the LSI firmware package to the CDROOT folder that was extracted from the FDOEMCD.zip file.

    Note: the following firmware is based upon the model of SAS HBA controller you have. In my example, I am flashing a 9201-16i SAS/SATA HBA Controller.

    9201-16i.bin – Under Firmware\HBA_9201_16i_IT directory
    sas2flsh.exe – Under sas2flash_dos_rel directory
    mptsas2.rom – Under sasbios_rel directory
  5. Run makeiso.bat from the root of FDOEMCD folder.
  6. Use the created file fdoem.iso to either remotely mount an ISO image or use Rufus to create a bootable USB.
