I'm trying to switch the rig in my signature from a PCIe card to integrated graphics for a HWBOT contest.

BIOS setting of igfx for primary display does not stick and BIOS uses the PCIe VGA.

I tried several times with no PCIe card installed. BIOS does not find the igfx and does not finish POST when igfx is the only choice. POST ends with code A0, the white VGA led lit and a blank screen.

Igfx is not found by Windows 7, so the Intel driver cannot be installed.

A clue to the problem is that BIOS settings System Agent tab shows the "Integrated Graphics VBIOS version" as N/A.

The above happens for BIOS version 801 and factory original 401.

Any help?

It is my understanding that because of the ocing nature of the Apex that integrated graphics is not possible !....:(

Specs on the product site and in the users guide list integrated graphics via the rear panel HDMI and Display Port connections ... else why have the HDMI and Display Port there.

Several users of the Apex have already submitted 3D benchmark scores to that contest.

do you have a raid set up? how about csm...

The A0 QCODE suggests that you should be inside your OS.

Do you have a speaker connected to your system? Try hitting the Shift key rapidly 5 times to trigger Sticky keys. If you're inside your OS, you should hear a beep.

Yes, Chino, thank you. It is in Windows. I stand corrected. Even when I bang the delete key to get to BIOS settings, it progresses to Windows.

Then your system is working correctly. You're just not seeing any image when using the iGPU. Check your monitor's settings or maybe your HDMI/DP cable that you're using.

Also when you're presented with the problem again, try disconnected then reconnecting whatever cable you're using. It's worth a try.

Okay, tried those. I get no igfx when using the same monitor and HDMI cable that works with the PCIe card ... disconnected and reconnected between the two many times.

BIOS cannot find the igfx and proceeds to A0 with the white VGA LED lit whether I use the START button, the SAFE BOOT button or bang the delete key.

Needless to say, this is all with cleared CMOS and the CPU etc. run properly when a PCIe VGA is installed.

I am most concerned that BIOS does not have any version number for video bios. According to
http://www.intel.com/content/www/us/en/support/graphics-drivers/000005749.html
video bios for integrated graphics is expected to be included in the system BIOS. Re-flashing and trying other BIOS versions seems like a thing to try.

have you tried BRenamer

Who? Why?

apex drivers, bios utilities it's an app. I through it might be useful or not. any progress ?

Oh, the BIOS renamer. I find it much easier to rename manually. In the last hours I have put 3 versions of BIOS on a thumb drive, each renamed to M9A.CAP.

Resulting progress was negative. Versions 701 and 906 are added to the list that behave the same. I fear I am missing some BIOS setting. Perhaps someone has had the same difficulty. Perhaps it's just this one APEX board. My next try is to swap in another CPU.


Please note in considering loose cables or monitor difficulty, that the symptom there is a blank display and the white VGA LED is OFF. The white LED being ON is symptom of BIOS finding no video adapter.

This is not resolved and may be worse than I thought. The exact same condition appears when trying to use internal graphics with

M9 Apex BIOS 701, 801 and 906
M8 Extreme BIOS 1402, 3201 and 3401
three different 7530K - Kaby Lake BIOS versions
two different 6700K - All the above BIOS versions

In all those cases, the System Agent PCIe tab lists video BIOS as N/A and post does not find any VGA when there is no PCIe card installed. The white VGA LED remains lit while booting proceeds to its conclusion (Windows with the boot LED off or what should say 'press F1' for safe boot or a new processor with the boot LED on.) The same motherboards, BIOS, CPUs, cable and monitor work properly with a PCIe VGA. I think I'm doing something consistently wrong, or is there a consistent problem with all those versions of BIOS?

All those CPUs, cable, monitor etc work with internal graphics on another non-ASUS Z170 motherboard. I'll have to use that for the contest.

#1 Make sure you don't have LN2 Mode Enabled
#2 Clear CMOS
#3 Measure GPU Voltage at the ProbeIt points after starting without an external VGA

THANK YOU. Trying with LN2 mode disabled as soon as I can.

LN2 Mode disables the IGPU for safety reasons (it can take damage from the increased voltages).

Thanks again. I may have known that in the past, because i've used iGPU before. Obviously I forgot. That was the consistent error I made with the M9A and M8E.
