I have a DB85FL desktop board which appears to be faulty and i managed to lock myself out of it. I was trying out a new PCIe VGA but it would not show under windows or even in bios setup under pci devices (shows as unpopulated). As a last resort I disabled primary on-board display and now i cant get back in. the system beeps 2 long beeps then pauses a bit and repeats (so 4 beeps in total which is code for video error as the manual says).
I have tried every tutorial out there on resetting the CMOS. removed the jumper completely like described in the manual for resetting, switched to position 2-3 instead of 1-2, removed battery for several hours with psu both connected and disconnected, left it for several hours, shorted the + and - battery contacts while residual power was still present (led was on), you name it! nothing is resetting the bios to default back to the on-board vga. what's interesting is im sure it's booting into windows, im checking on my dhcp clients and verify that indeed its acquiring an IP address. I cant remote desktop since it appears to be disabled.
when i remove the jumper and turn on the computer, the beeping is gone. ive tried to guess restoring default values in bios while working "BLIND", as in pressing F9 --> Y --> enter --> F10 ... and so on (its intel visual bios). also tried blindly using the power button menu. i realize it's faulty but we dont have intel partners or authorized dealers in my country (online customer support verified its still under warranty) and since its booting into windows, i just need to be able to re-enable on-board VGA and disregard the option for PCIe completely. Any ideas??
