    AMD w4100 doesn't display video until OS loads

      Hello, I'm encountering a very frustrating issue with the AMD firepro W4100. I'm using the included mini display port to DVI adapter. When attached to an older flat screen monitor via DVI cable to the adapter, I can't get video to display at all even though I can tell by POST code that the machine is done booting. On a newer monitor using the same mini DP=>DVI adapter and cable to its DVI port, I get video but not until the OS (RH linux) starts to load. It is apparently impossible to get into BIOS, which isn't acceptable. Anyone have a clue why this is happening? The motherboard is an ASrock EPC612D8A, 32Gb of DDR4, Xeon E5-1603v3. Thank you for any insight, this is very annoying.
