Reflashing ServeRAID cards to vanilla LSI firmware

M1015 -> LSI 9220-8i (SAS 2008)

1. Make a bootable DOS USB stick (left as exercise to reader)
2. Get files from here
3. Extract files to USB stick
4. Get latest firmware from here
5. Overwrite 2118ir.bin and 2118it.bin on the USB stick from the latest firmware
6. Note down SAS address from green sticker on back of card
7. Boot from USB stick. If necessary, cd to dir containing extracted files
8. Wipe flash:

   megarec -writesbr 0 sbrempty.bin
   megarec -cleanflash 0
   

9. Reboot from USB stick again
10. Flash with relevant ROM (IR = RAID controller, IT = no RAID, just JBOD):

    sas2flsh -o -f 2118ir.bin -b mptsas2.rom
    

11. Set SAS address:

    sas2flsh -o -sasadd 500605b0xxxxxxxx (x= numbers for SAS address)
    

12. Reboot

To update in future, you only need to do the sas2flsh -o -f 2118ir.bin -b mptsas2.rom step
