NVIDIA Flash ROM utility
Version 04.14
Usage: 
file         f <filename> Flash the ROM using <filename> (no confirmation),
                             then do compare and ~CRC32.
save         b <filename> Read ROM and save to <filename>.
compare      k <filename> Read ROM and compare with <filename>.
tv           x <filename> Transfer TV data from file to EEPROM.
version      v <filename> Display file version and ~CRC32
                             (if no filename, acts on ROM).
erase        e            Erase the ROM.
display      d [bytes]    Display 256 the first bytes of the EEPROM
                             (default is 256 bytes)
check        c            Check for supported EEPROM.
nolight      l            Don't light keyboard LEDs.
overridetype p            Don't pause if file & chip PCI VenID/DevID mismatch.
overridesub  u            Don't pause if file & chip PCI subsystem ID mismatch.
reboot       h            Reboot the PC after other tasks completed.
protecton    w            Write protect ROM (only works on some ROMs).
protectoff   r            Remove ROM Write protect. (only works on some ROMs).
list         a            List all NVIDIA display adapters found in the system.
index        i <index>    Force a specific device index.
help         ?            Display this screen.
silence      s <level>    Silence level:
   default  All beeps.
   #=4 (or 2)   No progress beeps.
   #=5 (or 1)   No beeps.
override     o <level>    Override safety check level:
   default  unknown EEPROM | NV chip aborts application.
   level=1  unknown EEPROM acceptable for read operations.
   level=2  unknown NV chip acceptable for read/write  operations.
   level=3  Combined effect of 1,2 (cannot write to unknown EEPROM).
