Here are the files and steps to flash your Dell Perc H200 card and leave it in IT mode with UEFI support.
Download all the files from the link Here.
Prepare a USB with freedos bootable.
Copy all the files to the USB. Overwriting is not needed.
Boot into the UEFI console. This depends on your motherboard model. So, please, check the official documentation :)
map -b and find your USB filesystem. In my case was FS1.
fsX: to change to the USB filesystem. Replace X with your value.
sas2flash.efi -listall to find your Dell Perc H200 to flash the firmware. If you only have 1 card inserted (I recommend it), this should be 0.
sas2flash.efi -c X -list Replace X with your value, in my case was 0. Write down the SAS address as you will NEED this for UEFI and cannot be easily recovered.
Now restart the computer and boot the freedos USB. In the DOS prompt C:>:
megarec.exe -writesbr 0 sbrempty.bin
megarec.exe -cleanflash 0
Restart and boot the UEFI shell again. In the UEFI shell:
fsX: to change to the USB fylesystem. Replace X with your value.
sas2flash.efi -o -f 6GBPSAS.FW
Restart and boot the UEFI shell again. In the UEFI shell:
fsX: to change to the USB fylesystem. Replace X with your value.
sas2flash.efi -o -f 2118p7.bin
Restart and boot the UEFI shell again. In the UEFI shell:
sas2flash_p19.efi -o -f 2118it.bin -b mptsas2.rom
sas2flash_p19.efi -o -sasadd xxxxxxxxxxxxxxxx where xxxxx is your SAS address you wrote down earlier, without the hyphens.
sas2flash_p19.efi -b x64sas2.rom
Restart. Enjoy your Dell H200 in IT mode :)
