It should automatically do everything required to flash the card. If you don't get any unexpected errors and it completes, we need to reboot and program the SAS address back to finish. See the following note.
**Note:** For some reason, if power is not reset, the very first boot after crossflashing the card will cause a kernel panic - I believe it's iDRAC not letting go of something. This only happens the first reboot after crossflashing. There's two ways around this. If you don't have physical access to the server, just reboot now as normal back into the live ISO - the first time you'll get a kernel panic, and it will reboot again. Reboot back into the Live ISO, and the second time it will be fine as IDRAC is now aware his son is gone.
The easier way if you have physical access to the server, just completely remove power (unplug all power to the server and wait 20 seconds). Then plug power back in and boot the server back into Linux.
**Note:** For some reason, the very first boot after crossflashing the card will cause a kernel panic - I believe it's iDRAC not letting go of something (I was able to see the card put in a fault state via the debug UART when this happens). This only happens the first reboot after crossflashing. When you boot back into the live ISO and get the panic, either let it reboot itself, or use iDRAC to force a reboot. After that boot back into the live ISO again and all will be well.
## Programming SAS Address Back
Now rebooted back into the live Linux image, just run the following command, filling in the example address with your own, that you noted down earlier:

It should succeed without errors. That's it! You can run the following command to get some info about your new card. You should be able to see your SAS address and the same firmware version:
