Bios upgrade during power failure

Hello Joas02,

You may start with a flea power drain and check results.

If it doesn't work they try clearing the NVRAM with the RTCRST Reset Jumper.

drain flea power (shut down, disconnect power cables and Network cables, hold in power button 20 seconds with cords removed).  After flea power drain, system has to set for 3 minutes for DRAC to reset without any power plugged in, then plug in NIC and power but wait 2 minutes before power on to give DRAC time to initialize.

Hi @Joas02,

I notice you have posted another new title which is the same as this, so we have combined the new post to your existing one to avoid any confusion. 

You can upload it into Youtube and post the video URL here, we'll be able to view the video.

Unfortunately, it seems like the BIOS is corrupted and had affected the mainboard to not function. Hence, the only solution is to replace the mainboard.
