System currently defaulted to typical configuration settings ?

[Server-Support]

I've got Proliant DL 360 G7 which is behaving erratically, it always lose the iLO configuration (IP address kept on changing by DHCP) and everytime I reboot the server it always taking so long time to show the POST screen, because it must go to the memory diagnostic screen.

I also see there is a glimpse of error during the reboot mentioning about 

System currently defaulted to typical configuration settings

Somehow the OS running is not affected by this, I wonder what could be the cause and the solution to this issue ?
