Hello, i have an HP 220 raid card (SAS2308) in IT mode, and i need it to flash to IR mode. The only way i could do it is thru EFI USB flash drive. I can run sas2flash.efi.
When i wantto directly overwrite the firmware, it say it cannot be done

I tryed to erase IT firmware (sas2flash.efi -o -e 6) and than flash IR firmware (sas2flasf.efi -f 2308r207.rom) but i get an error NVSRAM is required to flash ir firmware.

Any advice pls.

sry for my bad english
