I suppose you have both the RAID Key and DIMM installed right? What's the BIOS version of your S5520UR board? Did it give any other messages besides Exit code = 17?
Yes I believe the RAID Key and DIMM are installed. The BIOS is the latest version, 0.61 and the so is the backplane HSC 2.17.
In a manual called "Intel RAID software users guide", "d29305019_raid_swg_r19_0.pdf" Table 14 MFI messags number 17 says: info Flash downloaded image corrupt. I downloaded the image again, and retried with the same result.
Full feedback after running update.nsh from EFI 2.0:
Adapter 0: Integrated Intel RAID SROMBSASMP2
Vendor IS 0x1000, Device ID 0x60
Package version on the controller: 9.0.1-0041
Package version of the image file: 11.0.1-0036
Exit code = 17
I mean this error occurs when the version check told that the old fw is too old for the new fw.
In this case you have to update with following commands:
efi\cmdtool2 -adpfwflash -f MP2_1007.rom -noverchk -aall
( -> you have only to read the readme and follow the uefi update instructions...)
or edit the update.nsh:
CmdTool2.efi -adpfwflash -f ..\..\MP2_1007.rom -noverchk -aall
