Update and to know the 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."
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 !!
