I have download this package before, but don't find a IT firmware or instruction about how to turn IR to IT.
After runing rms2ll080.nsh, the result is IR firmware.
I have solved.
Download p05 ver. firmware tool (sas2flash.efi), p20 ver. IT Firmware (2118it.bin) and p20 ver. BOOT ROM (mptsas2.rom) from avago/lsi website.
Copy sas2flash.efi, 2118it.bin and mptsas2.rom to a USB driver.
Reboot and enter EFI Shell.
FS0:>sas2flash.efi -o -f 2118it.bin
Then got a message about NVDATA mismatch, Y/N continue ?
Press Y to continue.
FS0:>sas2flash.efi -o -b mptsas2.rom
After initialize, Ctrl+C enter HBA's BIOS, the Adapter name change to LSI 9211-8i, and the FW Revision is 20.00.04.00-IT.
