Firmware Location The CNA Board contains a microprocessor (U20) which is responsible
for controlling all board functions and features. This board contains
firmware version 1.xx (the “xx” designator may vary but does not

location of the firmware chip (UMA1). The setup and configuration
data for the Adapter board is stored in the EEPROM memory located
on the main control board of the Drive.
