as you can see Intel 945 motherboard. I need to know how to do that my computer can turn on on some certain time.
I looked in BIOS there is nothing like Wake on time or alarm. Even in manual (pdf) nothing.

Does anybody know to turn on computer on time ?

Lots of other motherboards' BIOS has Alarm but I don't thing my BIOS support
that. I also tried with this code:

#include <stdio.h>
#include <linux/rtc.h>
#include <sys/ioctl.h>
#include <sys/time.h>
#include <sys/types.h>
#include <fcntl.h>
#include <unistd.h>
#include <errno.h>

int main(int argc, char **argv)
{

int i, fd, retval, irqcount = 0;
unsigned long tmp, data;
struct rtc_time rtc_tm;

fd = open("/dev/rtc", O_RDONLY);

if (fd == -1) {
perror("/dev/rtc");
exit(errno);
}

if (argc < 2) {
fprintf(stderr, "need an argument: time when we wake up\n");
return -1;
}

sscanf(argv[1], "%d:%d", &rtc_tm.tm_hour, &rtc_tm.tm_min);

rtc_tm.tm_sec = 0;
if (rtc_tm.tm_sec >= 60) {
rtc_tm.tm_sec %= 60;
rtc_tm.tm_min++;
}
if (rtc_tm.tm_min == 60) {
rtc_tm.tm_min = 0;
rtc_tm.tm_hour++;
}
if (rtc_tm.tm_hour == 24)
rtc_tm.tm_hour = 0;

retval = ioctl(fd, RTC_ALM_SET, &rtc_tm);
if (retval == -1) {
perror("ioctl");
exit(errno);
}

/* Read the current alarm settings */
retval = ioctl(fd, RTC_ALM_READ, &rtc_tm);
if (retval == -1) {
perror("ioctl");
exit(errno);
}

fprintf(stderr, "Alarm time now set to %02d:%02d:%02d.\n",
rtc_tm.tm_hour, rtc_tm.tm_min, rtc_tm.tm_sec);

/* Enable alarm interrupts */
retval = ioctl(fd, RTC_AIE_ON, 0);
if (retval == -1) {
perror("ioctl");
exit(errno);
}

close(fd);
return 0;

}


Any other solution ?
