.TH set_timer 8 "Jul 07 2004" Linux "NVRAM WakeUp"
.SH NAME
set_timer \- Assuming a fixed wakeup time in the BIOS, it modifies the
system time, so that it will wake up after the specified sleep time.
.\" ********************************************************************
.SH SYNOPSIS
.\" The general command line
.B set_timer
.I timer_enabled
.I sleep_time
.\" ********************************************************************
.SH DESCRIPTION
.B set_timer
is for BIOSes 
.B nvram-wakeup 
can't handle, because there is no way (known to the author) to change 
the wakeup time in the NVRAM. One of the reasons might be that the 
settings are stored in the upper nvram and the manufacturer is not 
cooperative in sharing the information how to access it. One of the
reasons is that the checksum is computed in a way we can't see and the
manufacturer is not  cooperative in sharing the information how the
checksum is computed.

For such boards the wake up time must be set to 23:59:59 the day must be 
set to 31. If your board supports a month setting for the wakeup, set it 
to July.
.B set_timer
will modify the time in the hardware clock in a way that the computer will
wake up at the right time. 
It will also remember, by which amount of time the clock was changed and
restore the correct time on boot.


The System should not update the hardware clock in the shutdown process.
In Debian Woody set HWCLOCKACCESS=no in /etc/default/rcS
.\" ********************************************************************
.SH OPTIONS
.TP
.I timer_enabled
if 0 disables the wakeup, otherwise enables it.
.TP
.I sleep_time
the number of seconds from now, when the system should wake up
