Default How can I make motherboard to restart after power loss automatically?

I want to use a computer with AOpen AX59Pro motherboard as a server. It
means, that it has to run all the time. Unfortunately, after power loss it
will stay turned off, because it's ATX mainboard. How can I change it, and
make it to restart automatically after each power interrupt?
Of course it doesn't have 'Restart on Ac Power Loss' option in BIOS...
If not by software means then maybe I could achieve this by some hardware
trick? By changing jumpers, closing some cables, etc... It's very important
for me, thanks very much for response.

thanks a lot

PS. I'll paste below part of documentation concerning Power Management
feats. Maybe somebody will find something that I couldn't?

This is a specification of ACPI and supported by
hardware. When Enabled, the soft power switch on
the front panel can be used to control power On,
Suspend and Off. If the switch is pressed less than 4
sec during power On, the system will go into Suspend
mode. If the switch is pressed longer than 4 sec, the
system will be turned Off. The default setting is
Disabled, soft power switch is only used to control On
and Off, there is no need to press 4 sec, and there is
no Suspend.

the system enters into Doze mode. In this mode, the
CPU clock slows down. The ratio is specified in the
"Throttle Duty Cycle". Any activity detected returns
the system to full power. The system activity (or

Power Management a Modem Wake Up
Modem Wake Up
This motherboard implements AOpen special circuit
to detect modem ring signal and wakeup from soft
power off. The most possible applications are
automatic answering machine and fax send/receive.
It does not like traditional green PC suspend mode,
the system can be true power off, (identified by the
fan of your power supply is off). You can use external
box modem or AOpen MP56/F56 internal modem
card for modem ring-on, but MP56/F56 is
recommended, since MP56/F56 has special circuit to
cooperate with this mainboard and the modem power
and system power can be off together.

This option lets you enable or disable the RTC Wake
Up function.

WakeUp Date (of
This item is displayed when you enable the RTC
Wake Up Timer option. Here you can specify what
date you want to wake up the system. For Example,
setting to 15 will wake up the system on the 15th day
of every month.

system on the specified time (which can be
set in the WakeUp Time item) every day.
