Thanks
@nephri for pointing me in the right direction!
With 'Google is my friend' hopefully I have the correct files and set up the USB correctly.
My motherboard supports UEFI, but I'm not sure it has a 'built in shell' so I've included a bootx64.efi that I have extracted from my Win7 O/S, as per:
Creating Windows UEFI Boot-Stick in Windows - Thomas-Krenn-Wiki
My USB looks like:
\EFI\BOOT\BOOTX64.EFI
ibm_fw_sraidmr_1000-20.11.1-0184_windows_32-64 (IBM M1015 firmware v20.11.1-0184 for Microsoft Windows) (exe file)
sas2flash.efi
So I imagine the process would go: boot UEFI in bios, (my M/B asks me to select the boot file in the UEFI in the bios)
then running the following commands:
sas2flash.efi -o -e 6
sas2flash.efi -o -f 2118it.bin -b mptsas2.rom
sas2flash.efi -o -b x64sas2.rom
sas2flash.efi -o -sasadd 500605b0xxxxxxx (x=SAS address)
would this be job done?
because I'd hate to brick my M1015 card.
Many thanks for your confirmation!
