To boot the controller from firmware on the card, turn the controller off and insert the card in
the controller’s card slot. Turn the controller back on. (Or insert the card and immediately reset
the controller.)
If the boot directory exists on the card, the STAT LED blinks green three times, quickly. Firmware

If the STAT LED blinks green two times, either the boot directory is not present, the firmware file
is invalid or does not match the controller, or the controller is an SSD controller.

When the STAT LED no longer blinks steadily, but blinks only once every five seconds, remove

controller, or use a card reader with your PC and simply copy files with Windows Explorer.
NOTE: The controller must have firmware version R8.4a or higher and loader version 5.1b or higher.

Check the boxes if you want to save the strategy to flash memory and/or autorun it. If you are
just testing the strategy, don’t save it to flash.
Autorun works if you insert the card and then turn on the controller; it has no effect if you insert
the card when the controller is already turned on. (If the controller is already turned on, the new
