As a little hobby project I want to build a pfSense router with some scrap I found and some parts I bought on eBay.
The motherboard is a MS-7728 Ver 2.0. The problem is that the motherboard only have one full length PCI express slot and two short slots. The two short slots are basically useless as neither the NIC or the graphics card can fit.
The system boots fine with OS and graphics card. However if I run the system with only motherboard, PSU, CPU and RAM, it doesn't seem to boot. It makes a long beep sound and then two shorts. It keeps repeating like that.
Why doesn't my system boot properly without a graphics card, and is there any way I can fix it?
