SiFlashTool [/BusNum:xx /DevNum:xx] [/File:filespec] [/v]
Where:
BusNum / DevNum: These parameters specify the PCI bus and device number respectively of a Silicon Image storage controller. These parameters only need to be used if there is more than one Silicon Image storage controller in the system.
File: This parameter specifies the path and name of the BIOS image file to be programmed.
/V: This switch causes the program to only display the version number of a controller's BIOS. No BIOS image is programmed when this switch is used. The /File parameter is ignored if specified along with this switch. If /BusNum and/or /Devnum are specified, then only the BIOS versions of controller's at the specified PCI locations are displayed.
