nvram-wakeup

Read/write the WakeUp time from/to the BIOS

nvram-wakeup can read and write the wake up time in the BIOS (via /dev/nvram on recent 2.4.x kernels or direct I/O port access). On this wake up time the computer will be powered on automatically from the soft-off state. For the video disc recorder VDR, nvram-wakeup installs a hook script, that allows VDR to set a wake up time, when it powers down.
