"Failed to initialize PAL." while upgrading an LSI 9211-8i to IT?

Hit my head against the wall (a lot) on this. For me, solved it by:

• Formatting the USB as freedos (using Rufus) - https://www.all4os.com/windows/create-a-bootable-ms-dos-or-freedos-usb-drive.html
• Downloading the Shell_full.efi, renaming to shellx64.efi, and putting it on the root of the drive - https://svn.code.sf.net/p/edk2/code/trunk/edk2/EdkShellBinPkg/FullShell/X64/Shell_Full.efi
• Downloading the sas2flash.efi - http://www.lsi.com/products/host-bus-adapters/pages/lsi-sas-9211-8i.aspx#tab/tab4
• Booting to the ASUS bios and loading EFI shell (it's the last step, in the last page on the advanced screen on the bottom of the page, same page as "Save and Reset"

• Follow the rest of the instructions on this page (http://digitalcardboard.com/blog/2014/07/09/flashing-it-firmware-to-the-lsi-sas-9211-8i-hba-2014-efi-recipe/)

  ; to show the controller and verify the current version.
  sas2flash.efi -listall 
  
  ; to erase the BIOS, do not reboot after this command.
  sas2flash.efi -o -e 6
  
  ; to write the new firmware and BIOS.
  sas2flash.efi -o -f 2118it.bin -b mptsas2.rom

Update and to know the reason:

Reason:

i cite from http://brycv.com/blog/2012/flashing-it-firmware-to-lsi-sas9211-8i/ : "I booted from the SD card and attempted to run sas2flsh but was met with an error: “ERROR: Failed to initialize PAL. Exiting program.” Fortunately, article 16266 mentions the error at the end and directs you to article 15807. The gist of article 15807 is that Intel 3000 or 5000-based boards have optionROM limitations which cause the above error. The easiest solution is to use a different system. Alternately, you can use the UEFI installer."

Update:

The sas2flash.efi ist now available from Broadcom The files on the LSI web page is no longer available. E.g. search for the file installer_p12_for_uefi.zip or using the Link.

Current Version: installer_p20_for_uefi.zip

Thanks to aronchick for the hint to sas2flash.efi !!

I ran into the exact same problem with updating the LSI SAS 9211-8i ("Failed to initialize PAL"), and found an unlikely solution: A firmware update was possible from within the MegaRAID Storage Manager running under Windows, there's a link "Update firmware" right on its dashboard.

After hours struggling with this error I was finally able to do it booting off a Windows 10 USB and went into Repair / Advanced / Commandline and was able to run the dos commands to update the card.
