463 help
464 Enable the PM code's memory area checksum over sleep. This option
465 will generate CRCs of all blocks of memory, and store them before
466 going to sleep. The blocks are then checked on resume for any
467 errors.

469 Note, this can take several seconds depending on memory size
470 and CPU speed.

479 Set the chunksize in Kilobytes of the CRC for checking memory
480 corruption over suspend and resume. A smaller value will mean that
481 the CRC data block will take more memory, but wil identify any
482 faults with better precision.
