A system and method for providing a secure image load. The system includes a microcontroller. The microcontroller has a plurality of physically modifiable internal components (PMIC). Each of the plurality of PMICs can only be modified one time. The system further includes an image loader configured to load a boot image from the memory of the microcontroller, and a checksum calculator configured to calculate a checksum value for the boot image. The system further includes a checksum burner configured to modify the plurality of PMICs to create a binary representation of the checksum value for the image. A checksum value is calculated for the image. This checksum value is written to the microcontroller. The value is burned into the microcontroller using the PMICs. Further, responses to the checksum mismatch are burned into the microcontroller using the PMICs that are present in the microcontroller.
