-- Commands and Options --
help ? Display this screen.
save b <filename> Read EEPROM and save to <filename>.
compare k <filename> Read EEPROM and compare with <filename>.
verify h <filename> Verify <filename> matches EEPROM if flashed.
tv x <filename> Transfer TV data from file to EEPROM.
version v <filename> Display file version and ~CRC32
(if no filename, acts on display adapter).
listpatches Display list of runtime ROM pack patches
applied at boot (primary only).
display d [bytes] Display 256 the first bytes of the EEPROM
(default is 256 bytes)
check c Check for supported EEPROM.
protecton w Write protect EEPROM (only on some EEPROM's).

format is: AND Mask 0, OR Mask 0, AND Mask 1, OR Mask 1
Press 'Enter' to continue, or 'Q' to quit.
guid q <guid> Set the IEEE 1394 GUID in the firmware image
(GUID is in the form of 16 hex digits).
guidsource 1 <location> Set the source of the IEEE 1394 GUID.
main - main EEPROM image
dedicated - separate serial EEPROM part
list a List all NVIDIA display adapters found in the sy
stem.
pciblocks List all the PCI ROM Images stored in the EEPROM
.
upgradeonly Only allow upgrading of firmware based on versio
n.
overridetype 5 Allow firmware and adapter PCI device ID mismatc
h.
overridesub 6 Allow firmware and adapter PCI subsystem ID mism
atch.
reboot y Reboot the PC after other tasks completed.
keepstraps g Keep the soft straps already present in the EEPR
OM
after flashing the new image.
romstrap j Override the ROM strap setting to allow flashing
an
image when grounding the STRAP_SUB_VENDOR pin.
This allows flashing a corrupted or erased EEPRO
M.
Note: Make sure there is a physical EEPROM prese
nt
when using this option
index i <index> Force a specific device index.
filterdevid f <value>[,<mask>] Filter device list by device ID and optional mas
k.
fwindex F <fw index> Index of which firmware image to use from a firm
ware
bundle.
auto A When possible, run without user intervention.
silence s Silence all audio beeps.
Press 'Enter' to continue, or 'Q' to quit.
beep ! Beep to signal updating progress.
nolight l Do not light keyboard LEDs.
override o <level> Override safety check level:
default unknown EEPROM | NV adapter aborts application.
level=1 unknown EEPROM acceptable for read operations.
level=2 unknown NV adapter acceptable for read operations.
level=3 Combined effect of 1,2 (cannot write to unknown EEPROM or adapter).
log L <log file> Create a log file.

Use a single dash ("-") to use the single letter version of a command.
Use a double dash ("--") to use the longer descriptive version of a command.
Use equals ("=") to specify parameters, with separating commas (",").

NVIDIA Firmware Update Utility (Version 5.118)

NVIDIA display adapters present in system:
<0> GK1xx (10DE,1189,1462,2842) H:--:NRM B:01,PCI,D:00,F:00

Display adapters? GK1xx should be GK104 as that is the codename of the GTX670 which I have in my system.
