if you put in the 1.4 utility disk it will ask you to update if it not already at 1.4, after the update you will see at the top HW 1.1b FW 1.4. FW means the firmware on the spi chip which is 1.4 ane HW mean the firmware on the actel chip which is currently 1.1b on d2cpro9 v1 and 2.0 on d2pro9 v2. If you put in a 1.3 utility disk into a d2pro9 with 1.4 it will ask you to downgrade, i dont know if the downgrade works or not never tried and i dont think i will try.
