I am running 2 "ASUS HD7850-DC2-2GD5 Radeon 2GB DDR5 VGA/DVI/HDMI/DisplayPort GPU Tweak Utilities PCI-Express 3.0 Graphics Card HD7850-DC2-2GD5" using crossfire and in order to access the bios using F2, I must disconnect the HDMI cable and use the DVI port with a VGA cable. If I try it with the HDMI cable plugged in and continue to pressF2, the computer will display the boot menu and continue to reboot.
Video tab settings:
Integrated Graphics Device: Always Disable
Primary Video Adapter: Ext PCIe Graphics (PEG)
IGD Primary Video Port: Thunderbolt
IGD Secondary Video Port: HDMI
No Video Detected Error Beeps: checked
Intel@ Graphics Performance Adapters: unchecked
PCI Slots tab settings:
PCI Latency Timer: 32
PCI Bus Limit: 256
Any advise about being able to boot into the bios while my video card is using an HDMI cable for it's output would be greatly appreciated.
