Good time.
I have motherboards of the A520M PRO model (MS -7C96)

there is also a customized fogproject.
when you turn on the computer, only this happens:
checking media presence…
Media presence…
start pxe over ipv4 on MAC address: 00-00-00-00-00-00
In the server logs (command: tcpdump -i eth0 port 67 or port 68 -e -n -vv), in the 66–67 DHCP section, I get this:
