- MSI Bios version 2.80
- Raid option Rom is 13.1.0.2126

I used the UBU_v1_55_3 tool:
- Bios scanned: Found EFI Intel Raid Controller GUID 91B4D9C1-141C-4824-8D02-3C298E36EB3F
-Intel RST(e) OROM and EFI SataDriver
OROM IRST RAID for SATA - 13.1.0.2126
OROM IRST RAID for SATA - 13.1.0.2126
EFI IRST RAID for SATA - 13.1.0.2126

- Intel RST OROM and EFI SataDriver and selected- Update to v14.8.2.2397
- * Generate FFS Intel RAID Driver GUID 91B4D9C1-141C-4824-8D02-3C298E36EB3F …Ok!
* Update EFI Intel RAID Driver GUID 91B4D9C1-141C-4824-8D02-3C298E36EB3F …Ok!

OROM IRST RAID for SATA - 13.1.0.2126
OROM IRST RAID for SATA - 13.1.0.2126
EFI IRST RAID for SATA - 14.8.2.2397

- Saved the Mod Bios and flashed the motherboard…
- Rebooted and the Raid option Rom is still 13.1.0.2126
- Installed Intel RSTe Drivers & Software Set v14.8.9.1053
- Checked the Report and verified the Raid option Rom is still 13.1.0.2126

Any suggestions?

Thanks

That is absolutely correct, because the UBU tool updated the Intel EFI “RaidDriver” of your mainboard BIOS, but didn’t/couldn’t update the Intel RAID ROM due to a bug of the AMI Aptio V MMTool.

You should
a) enter the BIOS and choose the required UEFI boot settings (then you will get access to the internal BIOS tool named “Intel(R) Rapid Storage Technology”, which is using the updated Intel “RaidDriver” v14.8.9.1053) and
b) install the OS in UEFI mode (if not already done).
That’s all!
