Can't install 32-bit 10/100/1000 Mbps Ethernet LAN PCI Card to D865PERL (AAC27648-208). No proper booting, only fans are working. Can this motherboard support only one PCI LAN Card ore more (one only 10/100 and another new one 32-bit 10/100/1000 Mbps.
I understand that your system will stop booting when a PCI card is installed.
I can confirm that the motherboard is capable of having different cards installed and working together.
I recommend you to test with another card installed and if the problem also occurs, try testing the motherboard out of the chassis and testing with another power supply. The port on the motherboard may be bad also.
