For PROT-16: Internal Error
When issuing ocrconfig -replace it checks first about the size of the new OCR before making the replacement.
If it is acceptable then it will replace to the new OCR.
The acceptable size is either 128Mb or 256Mb and so on.
If the original OCR size was less than 128Mb, please make the new OCR as 128Mb or 256Mb.
If the original OCR size was less than 256Mb and greater than 128Mb,
please make the new OCR as 256Mb.
