Toughbook CF-53mk4 help w BIOS password removal

I have a toughbook I set a BIOS password to and forgot it and need to change it. I can't access windows as forgot the password for it as well.

I purchased a ch314a mini programmer and have dumped a bin of the chip mx25L12873F which gave me the full bios. I then tried to replace the password data in the AMITSeSetup section and in another area I found it. Upon reboot the computer says bad checksum and reverts itself!
