73 | help | |
74 | Enable the PM code's memory area checksum over sleep. This option | |
75 | will generate CRCs of all blocks of memory, and store them before | |
76 | going to sleep. The blocks are then checked on resume for any | |
77 | errors. | |
78 | ||
79 | Note, this can take several seconds depending on memory size | |
80 | and CPU speed. | |

88 | help | |
89 | Set the chunksize in Kilobytes of the CRC for checking memory | |
90 | corruption over suspend and resume. A smaller value will mean that | |
91 | the CRC data block will take more memory, but wil identify any | |
92 | faults with better precision. | |
