Thanks to the post by Bryn V. is was able to enable the RAID features on my LSI SAS 9207-8i controller.
Here are the steps: *** WARNING *** this could easily brick your controller. Please read Bryn’s and others post.
1) download the LSI UEFI installer: “Installer_P15_for_UEFI.zip
2) download the P15 BIOS and Firmware: “9207_8i_Package_P13.5_IR_IT_Firmware_BIOS_for_MSDOS_Windows.zip”
3) Extract to USB Disk “9217-8i.bin”, “mptsas2.rom”, and “sas2flash.efi”
4) Boot to UEFI BIOS
5) At the Shell> prompt type “map”
6) At the Shell> prompt type “fs0:”
7) At the Shell> prompt type “sas2flsh.efi -listall"
8) At the Shell> prompt type "sas2flsh.efi -o -e 7"
9) At the Shell> prompt type "
sas2flsh.efi
-o -f 9217-8i.bin -b mptsas2.rom"
10) At the Shell> prompt type “
sas2flsh.efi -listall"
I verified the BIOS was updated and rebooted.
Thanks a lot for this article!
After I downloaded the 9207_8i_Package_P20_IR_IT_Firmware_BIOS_for_MSDOS_Windows.zip file I was confused as it had the IR version for 9217-8i. Your article clarified all doubts.
Note that the “sas2flsh.efi -o -e 7” command erases the SAS number from the firmware, so it is better to use “sas2flsh.efi -o -e 6”.
