I post in this thread because some people looks to know about firmware and flashing. Sorry if I am hijacking the thread.

I have a DELL T7910 with a built in LSI 3008 controller. I use UEFI, No legacy bios and secure boot. I found a new Firmware in the for this computer relevant download on DELL Support, marked as valid for this computer according to service tag., I updated the firmware, without checking what version was alrady on it. Sorry… It is a Ph15 relase I flashed now No errormessages, the command to flash was: sas3flash_x64.exe -o -f T7910_LSISAS3008.fw -b mptsas3.rom -b mpt3x64.rom However it took very long time to reset the adapter. After a reboot I can no longer boot into windows. It cannot find any HDD. I have from UEFI choises to go to BIOD or device setup. I tried device setup but it only led me to Intel NIC. Not to the SAS controller. DELL dignose report it cannot find my HDD’s After I went to BIOS and found it cannot find any hardrive there. I then turned of secure boot. After a reboot, the adapter is there, working. Diagnose now find my harddrive. Rebooting and windows boots. Rebooting, inte BIOS and turn on secure boot. Once again UEFI do not accept the 3008 controller. Turning off secure boot, it works. What am I missing here? Is this firmware not certified for UEFI? Is there a way to tell UEFI it is valid, to enable secure boot? Or, is it a fault firmware package DELL have? Info about the firmware as follow.

I hope some of you know more about this issue. And, yes I am not familiar with UEFI, nor the new SAS controllers. Many years ago I worked with SCSI, so my knowledge is a bit old. Sorry if I missed something elementary here.

Yes it is IR. I do not understand what I would gain with reflash it to IT. Currently I do not use the RAID. All drives is unconfiguered. So I want it to work as a HBA and report drives to my motherboard. I plan on buying a SAS 9361-8i to the day I begin configure drives for RAID. I bought this computer as second hand some weeks ago, hence my efforts to update BIOS and firmware, it was untouched and I have a habit of updating things like this when I buy a second hand computer. This time, it almost worked. Is there a newer recomended firmware for this? On DELL support pages I found no newer. And yes, DELL claim on their support site that they have dropped the support for this model from this year. Also, the T7910 do not have a choise for UEFI shell when I boot.

Edit: After spent some time on Broadcom firmware page. Is it as simple as DELL copy the non-signed UEFI firmware into its package? They have repackage the archive and do not have the folders Broadcom have in their relase. Is it safe to asume DELL do not modify somthing else? Is it possible to downgrade if I try Broadcoms own and something goes wrong? Lots of question, sorry.
