1. A system for providing a secure boot image loading, comprising:
a microcontroller;
an image loader configured to load a boot image from memory of the microcontroller;
a plurality of physically modifiable internal components (PMIC) disposed on the microcontroller, wherein each of the plurality of PMICs can only be modified one time, wherein the plurality of PMICs include a binary representation of a checksum value for the boot image; and
wherein the image loader is configured to call a checksum calculator to calculate a second checksum value for the boot image each time the boot image is loaded, and to compare the second checksum value with the checksum value in the plurality of PMICs to determine if the second checksum value and the checksum value are the same.
