How to Set keyboard boot for Asus M2N68-AM se Motherboard

I have not found any information about the keyboard boot on this motherboard.

It took me a long time to complete the work.
The specific implementation process is as follows:
Step 1: Open the chassis and navigate to user manual 1-7 to set the jumper to + 5vsb
There are two jumpers and one is in the middle of the NIC and sound card + 5vsb

It doesn't matter if you find [PS2_USBPW1-4], [USBPW5-10]

[USBPW5-10] This is next to the hard drive interface

Step 2: Set the BIOS to 2.5.4 advanced power management settings (APM configuration) in user manual 2-12)
Set restore on AC power loss to [Power on]

Then, set power on by PS/2 kb/ms to [enabled] to save and exit OK.

Now you can boot the keyboard, without a specific key, any key (I think it is not very good) to boot.
