For using the "Flash EEPROM" utility: 1) Start "flasgeeprom.exe" and don't change any settings. 2) Click on the "Write EEPROM..." button. 3) Select the "Emuzed_LowProfile6.bin" or "Emuzed_LowProfile78.bin" image file and click "Open". 4) After finishing the programming of EEPROM, click on "Exit" button and reboot the system. Please note that this tool only works with single board. Therefore if you happen to have more than one card on the system disable all except one before running the tool. For 6 MHz channel bandwidth use the file "EmuzedLowProfile6.bin". For 7/8 MHz channel bandwidth use the file "EmuzedLowProfile78.bin".
