| APEI allows to report errors (for example from the chipset) |
| to the operating system. This improves NMI handling |
| especially. In addition it supports error serialization and |

| Generic Hardware Error Source provides a way to report |
| platform hardware errors (such as that from chipset). It |
| works in so called "Firmware First" mode, that is, hardware |
| errors are reported to firmware firstly, then reported to |
| Linux by firmware. This way, some non-standard hardware |
| error registers or non-standard hardware link can be checked |
| by firmware to produce more valuable hardware error |
| information for Linux. |

| ERST is a way provided by APEI to save and retrieve hardware |
| error information to and from a persistent store. Enable this |
| if you want to debugging and testing the ERST kernel support |
| and firmware implementation. |
