To invoke the board's Backup Firmware (in case you brick it while flashing BIOS)

Method #1

Turn off power via AC main switch on PSU.

Press and hold the ATX power switch then switch the PSU back on while still holding ATX power switch. Hold the power button until the PC starts and shuts down again.

Release the ATX Power switch, wait 5 secs and press it again. Backup Firmware should kick in. If not, repeat.

Method #2

1. Shut your PC down 2. Hold the power AND the reset button for about 10 sec, then release. 3. Backup BIOS should kick in anytime soon now.

 

this always works eventually... don't need a solder gun.

Oh I did that many times but it does not work on this mobo so that´s why i´m gonna try this third method I found.

 

Method 3, which explains to short/jump/bridge pins 1 and 6 on the M_BIOS chip to kick off a routine installed in firmware which reflashes a corrupt M_BIOS with the contents of B_BIOS, worked wonders for me, for which I'd like to thank the OP.

I had eliminated all possibilities other than the motherboard, and was about to RMA the board (which entails hefty shipping charges not to mention losing the board for a few weeks) when I discovered this thread and got Method 3 to work when nothing else would.

HOWEVER … at first I couldn't get it to work, despite trying a handful of times. What finally did it for me was when I stopped paying attention to the specific instruction of letting go of the pins when the power ON single beep is heard : on my board (a GA-H97-D3H) I had to KEEP HOLDING THE TWO PINS FOR 5–10 SECONDS after the initial beep before being rewarded with this pop-up message on my display :


====== DUALBIOS ======
The main BIOS is corrupted.
Press [ENTER] to recover the
main BIOS from the backup
BIOS.
            ❞

It may depend on the board, or maybe if the OP sees this he might know why … but if you have a dual BIOS board and method 3 didn't work for you and you're out of options, try it again but keep holding pins 1 and 6 with a steady hand for at least ten seconds after the initial beep, see if that doesn't do it for you. Did for me.

OK got a RX580 .. everything works except I am still unable to upgrade to 10.14.6 .. after rebooting,Graphics gets going .. I have to progress bar then i just crash and reboot.

 

If anyone has an idea ... or if someone that can install 10.14.6 could provide me with a DarwinDumper Dump .. might be something in the DMITables that could help

 

I think it thinks it has to do a firmware update somehow  and that it when it fails ...

Hey, I had to update via a genuine Mac. After it, it will boot. But still no drm etc.. I read somewhere that it might work if we spoof the rx580 into a rx580 pro.

If Method 1 and 2 doesn't work to kick in the Backup Firmware, it's easier to short Pins 5 and 6. You can do this with a screwdriver or a paperclip cause the Pins are next to each other.

Was able to update my Mojave test drive from 10.14.3 to 10.14.6 using this method 

1) Clone the drive with Carbon Copy Cloner

2) Boot from the clone and launch the 10.1.4.6 Combo Update to update the original

3) Success (reboot from the updated original)

Following this I tried to install 10.14.6 Supplemental Update  .. using the Software Update Control Panel ... was unsuccessful.

So I decided to try something different ...

 

1) I downloaded the Supplemental Update from Apple's site

2) I opened the dmg file and saved the .pkg file on a USB Stick

3) Boot in UEFI shell and then boot into the Recovery Volume

4) Once in Recovery Mode , select Utilities -> Terminal

5) in Terminal

 

installer -verboseR -pkg /Volumes/USBSTICK/thepackagefilename.pkg -target /Volumes/TheTargetVolume
6) Success

Hi Guys,

 

I have just been reactivating my nice and powerful desktop machine based on the Z77MX-QUO-AOS and i7 4770K and a GTX 770. It is still running - I think - the H3B.894M Firmware and currently booting El Capitan.

After all I have read here, a Mojave installation should be possible without major problems, however my current problem is, that the link in the wiki for the latest H20.167X-MASS BIOS doesn't seem to work for me. The one provided on Pastebin also is dead.

 

Could anyone advise me where to get the latest OZ Bios from so that I can get the horse up to date?

 

Thank you very much!

Warning : Trying to install Mojave 10.4.4+ the vanilla way will fail (with SysDef 13,2 for sure ), you have to upgrade to 10.14.1-2-3 and then use of the the method I just described above. (Good thing I have kept some of these installers)

It relates to some firmware upgrade Apple is pushing along ...

Sep 22 17:27:40 iMac OSInstaller[610]: ------- Install Failed -------
Sep 22 17:27:40 iMac OSInstaller[610]: Operation: Update firmware failed, Failure Reason: Error Domain=com.apple.osinstall Code=514 "" UserInfo={NSLocalizedDescription=, NSUnderlyingError=0x7f9ce3235f20 {Error Domain=PKXARArchiveErrorDomain Code=101 "archive verify failed" UserInfo={NSURL=file:///Volumes/Super%20Beta/Library/Updates/061-06469/FirmwareUpdate.pkg#Scripts, NSFileOwnerAccountID=0, NSFileHFSTypeCode=0, NSFileSystemFileNumber=3699854, NSFileExtensionHidden=false, NSFileSystemNumber=16777236, NSFileSize=172690619, NSFileGroupOwnerAccountID=0, NSFileOwnerAccountName=root, NSFilePosixPermissions=420, NSFileHFSCreatorCode=0, NSFileCreationDate=2019-09-22 15:47:25 +0000, NSFileType=NSFileTypeRegular, NSFileGroupOwnerAccountName=wheel, NSFileReferenceCount=1, NSFileModificationDate=2019-09-22 15:50:43 +0000, NSLocalizedDescription=archive verify failed}}}

 

Haven't found a way around it yet ...as far as I know it does not matter which boot loader you use... so if anyone is able to install 10.13.6 or 10.14.6 the vanilla way .. i'd like to know.

Why is this important .... Catalina is around the corner and it will push those firmware updates (it does in Beta)

Still digging...

 

Other stuff I been working on ...

 

1) Compatibility testing/migration plan/ failover plan before I upgrade from High Sierra to Mojave as my main OS now that I have a RX580.

2) OpenCore .. I am now convinced it cannot co-exist with Ozmosis in firmware ... one would have to go back to the Official F2N or F3A firmware ... not ready to go that route yet mostly cause this will take time I don't have right now (I am on 24/7 pager duty so I need to have a working computer)

I upgraded to 10.14.6 via .4 and .5 with the following defaults plus kernextpatcher.plist in the EFI, which I downloaded from here. KernextPatcher has 2 patches that are applied, one to all 10.14 and one to 10.14.6.

The other issue I have had (all along) is needing to edit the com.apple.Boot.plist in the Boot Files subdirectory of the install directory to add flagsnv_disable=1 to the kernel flags line, then booting from the boot.efi in that partition to complete the install. I can't find any legacy kexts for the NVidia card I used to have. I have an MSI RX560, which I saw on some list somewhere of supported cards for Mojave.

 

I'm using the XMAX-E ROM, for which I'm grateful! I think you put KernextPatcher into it.

Glad to know that it might be something unique to my setup....

Can you make a DarwinDumper Dump... BootLog, ACPI and DMI Tables (SMBIOS)..maybe I can spot something..


Yes, KernextPatcher is in the XMAX-E firmware, KernextPatcher.plist in EFI will override the one built into the firmware, so is DBounce but disabled by default unless you put DBounce.plist in EFI.

Thank you very much for the link, I already upgraded the BIOS accordingly. I haven't been able to get my Mojave installer ready yet, but does what you just wrote mean I'd have to start from a 10.14.0? I'd have no idea where to get that from.

 

For now I just had a High Sierra installer around, however as soon as I boot my installation flash drive, I am getting the prohibition sign and after a few minutes the machine turns off.

All right, I found the default.plist template, but now I am not quite shure where to put it. I found out so far that it goes in that folder you mentioned on the EFI partition, however at this point there is just a blank SSD with nothing on it in my machine.

 

Thanks for the patience!

The BIOS version in DarwinDumper does not match the one posted above ..so I guess you haven't done a PRAM reset since you edited Defaults.plist.

 

That's more than likely true - but it works...

Many thanks for the tips and sorry for the late reply it has been a bit crazy here so I have not had the time to do anything yet.

 

Hmm 5 and 6 instead of 1 and 6, maybe the author of that thread wrote the wrong number. Anyway that is just as you say much easier so now I only have to find out how they number the pins on this chip. I believe there is a small mark in one corner of it so if anybody can point me in the right direction to find the info or know how it is please tell.

 

It would be so super cool if I can bring it to life again without having to solder of the chip and replace it.

 

Edit:

If it is this chip in the link under here I am not sure if 5 and 6 are the right pins looks it could be 1 and 6 since the first pin is CS# which = chip select and 5 is SI/SIO0 which = Serial Data Input (for 1 x I/O)/ Serial Data Input & Output (for Dual Output mode) but I do not know nothing about this so if somebody could take a look would be very helpful.

I tried both pin 1 and 6 and 5 and 6 but no luck so I believe it needs new a new reprogrammed bios chip or both or a ride to the scrapyard.

      Vorrei assemblare un nuovo hackintosh partendo dallo stretto necessario per poi aggiungere altri componenti nel tempo. Dato che la mobo penso sia fondamentale vorrei prenderne una che mi dia la possibilità di future espansioni ma che non costi troppo. Ho visto che su Amazon ci sono delle mobo come ad esempio la Asrock Z370 Taichi usate ad ottimi prezzi. Voi che ne pensate? Vale la pena o è rischioso? Nella descrizione c'è scritto "Come nuovo" o "Ottime condizioni".
      Riguardo alla compatibilità di questa scheda madre con hackintosh che mi dite? Il modulo wi-fi e bluetooth è compatibile?
      Grazie.

      Ciao a tutti.
      dopo aver installato High Sierra il pc non può avviarsi dall'SSD mostrandomi la schermata nera che dice di scegliere il boot. facendo partire il pc con l'USB inserita, da dove ho installato il tutto, mi viene mostrata schermata di scelta dove posso effettivamente fare partire osx appena installato dal ssd ma con una lentezza mostruosa!. se provo con la chiavetta scollegata stessa schermata nera con la scelta del boot. inutile aggiungere che ho cercato di cambiare l'ordine di avvio dal BIOS, aggiornato il BIOS, ma senza successo. l'ssd funziona perché dopo ho installato da questo stesso anche linux o windows tranquillamente
      cosa posso fare? grazie a tutti

      Hello guys.
      This is not my first hackintosh, but this will be the first time to create a hackintosh with thunderbolt.
      First of all, i have read some info about MoBos with Thunderbolt, but im a bit confused.
      I need to create a working hackintosh with Thunderbolt 2/3 .
       
      At this moment i know that we got 2 options (Correct me if im wrong),
      -we can get one MoBo and ad a Pcie Card with thunderbolt (only if the chipset is compatible)
      -we can get one MoBo with thunderbolt integrated via USB-C connectors (like the new Macbook Pro)
       
      What are the possible MoBos that have integrated Thunderbolt vía USB (or directly thundelbolt ports)?
      I have read a lot of buyers guides from some webs , but a lot of that MoBos with thunderbolt enabled, are "discontinued" or without stock
      Should we only choose Gigabyte MoBos? 
       
      I Have been too looking at Gigabyte website, and seems that the Chipset Z170 its the only one with Thunderbolt (vía USB-C)
      ports.
       
      Could you help me with these please?
       
      Thanks You So Much!

      Hello.
       
      It's been about 3 or 4 years since I built my first, and so far only hackingtosh. I did so fallowing a guide written by good guy ^Andy^, witch came with hardware recommendations. I now feel it's time for me to upgrade to a faster system to keep up with heavier work loads. I'm strongly considering building a hackingtosh around the new i7-6700K Skylake processor, but I haven't come across guides for  this type of processor. I was wondering if any of you could recommend me a motherboard that's compatible and that won't become a hassle when trying to install OS X. Also, if there's a guide you know of, please let me know.
       
      Thanks in advance.

      Hi,
      I'm currently running a Windows 7 x64 PC with:

      8GB DDR3 Ram

      AMD FX 4170 GPU

      AMD Radeon HD 7870 CPU

      1TB HDD (Windows 7)

      150GB HDD (Blank)
       
      Gigabyte GA-970A-DS3 Motherboard
      I am aware that getting OSX on an AMD machine is not an easy task, but can it be done with my setup?

      I am currently running OSX 10.8.3 in VMWare which is OK but lags a fair bit and lacks any kind of 3d acceleration and would like to be able to dual boot it natively alongside windows on the 150GB HDD.

      Thanks
