| 45 | help | |
| 46 | Enable the PM code's memory area checksum over sleep. This option | |
| 47 | will generate CRCs of all blocks of memory, and store them before | |
| 48 | going to sleep. The blocks are then checked on resume for any | |
| 49 | errors. | |
| 50 | ||
| 51 | Note, this can take several seconds depending on memory size | |
| 52 | and CPU speed. | |

| 60 | help | |
| 61 | Set the chunksize in Kilobytes of the CRC for checking memory | |
| 62 | corruption over suspend and resume. A smaller value will mean that | |
