2.2 Step 2: Update CS18AI Firmware
6. When the download completes, open your Downloads
folder and CS18AI firmware folder.
7. Depending on your computer's system preferences, the
firmware .zip archive file might not automatically decompress.
If it doesn't, double-click the file, and it will decompress.
8. Open the firmware folder; you will find five files inside:
initvars.scr, recovery.scr, rootfs.img, and ulmage. You
will need all five files to upgrade your controller.
9. Connect a FAT32-formatted USB thumb drive to your computer.
