set_timer(8)

NAME

set_timer - Assuming a fixed wakeup time in the BIOS, it

modifies the system time, so that it will wake up after the spec

ified sleep time.

SYNOPSIS

set_timer timer_enabled sleep_time

DESCRIPTION

set_timer is for BIOSes 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. 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

OPTIONS

timer_enabled

if 0 disables the wakeup, otherwise enables it.

sleep_time

the number of seconds from now, when the system

should wake up
