Preparing a Binary Firmware Image for Pre-assembly Burning
In some cases, OEMs may prefer to pre-burn the flash before it is assembled on board.When pre-
burning, the GUIDs/MACs inside the image should be unique per device. The following are two
methods to pre-burn an image. You can choose the best method suitable for your needs.
Method 1: Pre-burn an Image with Blank GUIDs/MACs
In this method, the image is generated with blank GUIDs and CRCs. The GUIDs are set after
the device is assembled using the mstflint "sg" command. To set GUIDs take less than 1 second
when running on an image with blank GUIDs (through a PCI device).
To pre-burn an image with blank GUIDs/MACs:
Burn the image to a flash using an external burner.
(Optional) After assembly, query the image on flash to verify there are no GUIDs on the
device.
A device that is burnt with blank GUIDs/MACs will not boot as a functional network device
as long as the GUIDs/MACs are not set.
