| 782 | APM is a BIOS specification for saving power using several different |

| 784 | APM compliant BIOSes. If you say Y here, the system time will be |

| 787 | notification of APM "events" (e.g. battery status change). |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 789 | In order to use APM, you will need supporting software. For location |
