Table 106: Flash Firmware with ROM File
Convention MegaCli –AdpFwFlash –f filename [-NoSigChk] [-NoVerChk]-aN|-a0,1,2|-aALL
Description Flashes the firmware with the ROM file specified at the command line.
The –NoSigChk option forces the application to flash the firmware even if the check word on the file does not match the
required check word for the controller. This option flashes the firmware only if the existing firmware version on the controller
is lower than the version on the ROM image.
If you specify –NoVerChk, also, the application flashes the controller firmware without checking the version of the firmware
image. The version check applies only to the firmware (APP.ROM) version.
This command also supports the “Mode 0” flash functionality. For Mode 0 flash, the controller number is not valid. There are
two possible methods:
• Select which controller to flash after the controllers are detected.
• Flash the firmware on all present controllers.
XML output data is generated by this option.

MegaCli –AdpM0Flash –f filename
Description Flashes the firmware in Mode 0 with the ROM file listed on the command
line.
This option supports the Mode 0 flash functionality. For Mode 0 flash, the
controller number is not valid. The method to handle this is to flash the
firmware on all present controllers which are compatible with the image.
