New OS X compatible motherboard -> QUO

Recommended Posts

Gave it a shot and get nothing but a black screen on boot. The display turns on but but just sitswith there with no picture. No boot screen or anything. Trying to kick in secondary bios to flash my backed up bios now.

did you flash without the nv card? if not try removing the nv card and booting with onboard graphics and set the bios up before reinstalling the graphics card

No I flashed with the gtx installed. Never had to remove it before for a flash. I tried removing it but same problem. I haven't been able to get the secondary bios working yet but when I do I'll try flashing with it pulled.

Did you re-install vanilla first ? Cause I think TheKing mentioned something about the audio codecs .. VoodooHDA if discreet graphics and AppleHDA for iGPU .. so how does it handle a patched AppleHDA ...

figured I'd edit this cuz it sounded kind of dickish to me. Anyway...

I used a patched applehda for quite awhile with a discrete card with no issues other than having to rematch it all the time. Since switching to voodoohda I haven't had to do anything with audio for like 5 dp versions. It's been pretty nice.

!! Note on VoodooHDA, it covers ONLY the onboard codec and is enabled for the moment only for ALC892/ALC1150 !!

!! For discrete graphics HDMI/DP audio AppleHDA is used instead. Those who use internal GPU (IGPU) only will !!

!! have to disable VoodooHda and use AppleHda for HDMI/DP audio !!

 

To Disable loading VoodooHda.kext from Firmware

 

sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:DisableVoodooHda=%01

 

To Enable loading VoodooHda.kext from Firmware

 

sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:DisableVoodooHda=%00

Well I got into the backup bios and reflashed with the gtx pulled but I'm still getting a blank screen on boot. Could somebody who has it working post the bios? I think my copy may be corrupted.

 

Edit: Tried redownloading and flashing again. Same issue. Don't really know what to try here.

Post your exact configuration, that includes number of monitors connected and on what, type/model/connection type.

A tip, try with only one monitor connected on discrete GFX.

Check md5/sha-1 of the downloaded bios, is not healthy to guess and flash without to know...

checksum is good.

 

I have dual 2560x1440 monitors connected via DVI to the 690. They're a couple of reject Apple displays from Korea. I didn't have a problem with them going from 828 to 894.

 

Just tried with one monitor connected to the discrete card and still no joy. I also tried with the GTX removed and plugged into the IGPU.

 

One other non-standard component I have installed is an Apple wifi/bt combo card from here. Don't know why it would cause any problems though. It's been working like a champ.

Sounds like the board got damaged, judging your previous posts with random crashes/reboots, you tried to push overclock higher?

Disconnect everything then take out board battery, wait few minutes and put it back, then connect only one display to IGPU and mount only boot hard drive and only 2 sticks of ram(Slot 1 and 3).

Do you have pc-beeper mounted on board? If not try to find one so we can see if board gave some status codes.

If still does not boot, replace one by one, but keep 2 sticks of ram, until you test all 4.

Well I wasn't getting random crashes/reboots, I was just getting kp's whenever I tried to reboot, and it always happened after the screen went black at some point during the shutdown or startup (I'm thinking startup). It would come back up and give me the "your mac was restarted because of an error" message or whatever it says and prompt me to send a crash report to Apple (which I always click ignore on). Panic reports backtraces to graphics kexts. I just mostly chalked it up to DP issues.

 

I'll give your suggestions a try in any case and see how it goes. I was going to restore my bios backup of 894 and see if it booted. If it did would that tell you anything?

 

Also, when I restore from the secondary bios to whatever the stock bios was the quo screen comes up no problem.

 

one more bit of info: I have been overclocked to 4.3GHz but it's been rock solid. Maybe I should put it back to stock and try flashing (although I would think flashing a new bios would reset it anyway).

if it does then it may be the CSM video fail on those corean monitors, but i dunno the model, nor any more information, like if they get correct resolution(you can see if monitor have osd).

Asked for PC-Beeper, do you have one mounted onboard?

oops sorry. No I don't have a beeper handy and nowhere to get one until tomorrow. The monitors do have osd. They're running at full resolution now. I reflashed my backed up 894 and I'm back in Yosemite. Weird thing though: It kept booting normally and then when it should have brought up the desktop my monitor just stopped getting signal and went into power save mode. I switched one of the monitors to the IGPU and it booted up but was glitchy for a second and then just displayed static. I plugged it back into the GTX but into a different port (it has 3 DVI ports) and voila, back in Yosemite on 894m. I'm going to try flashing the bios again with this configuration and see what happens.

 

Edit: Having some weird Finder issues now though. Every time I try to open a folder it crashes Finder. I'll try repairing permissions and rebooting.

 

Edit2: Well apparently there's something wrong with my drive. Tried verifying it and that failed so I booted into recovery and it can't repair it so I'll have to backup and do a clean install. Bios will have to wait.

You have to activate the secondary bios. Turn your machine off. Push and hold both the start and restart buttons for like 5-10 seconds. The computer will start and turn off while you do this. I held them in for a few seconds after the computer shut back down. Then hit the power button again. It should restart a few times and then boot the secondary bios and go through the process of flashing back to the stock bios.

Haha dude I've had nothing but problems with my Windows drive. But no, I was never able to get my machine to boot with the new bios (so far). Now I have to reinstall to fix my OS X boot drive so I'll probably try the new bios again tomorrow or Friday.

Works fine here on 10.6.8/10.7.5/10.8.5/10.9.5/10.10 DP8 Windows7/Windows8.1 and Ubuntu.

Tested on IGPU Only, nVidia GTX 770 and ATI 5870 cards. 

 

Maybe this BIOS is too advanced for n00bs, so I advice them to stay with what works.

... the only problem is the f12 menù that see only mac drives

That is because you installed windows in Legacy mode NOT UEFI!

Maybe is time to do it proper...

Try disabling the boot entry filter. For you on quo board you would want nvram setting i guess.

 

// If DisableBootEntriesFilter NEEDS to be enabled, change second line bellow and set to true, then add both line in Defaults.plist

DisableBootEntriesFilter
