Warranty its void if use any of these mods,and there are no guaranty that this will work for all.
As u all already know QUO Aos get modified bios with Ozmosis bootloader.
This guide will help u use this fast and great bootloader on your board.
Ozmosis its a UEFI based bootloader that runs from firmware.
We have discovered some succesful mods using Aptio based boards from gigabyte.
Good bios versions are one that can write to nvram without using EMUVariableuefi clover driver.
To check that u need to install Clover and check if nvram varibles are stored after computer restart without using EMUVariableuefi.
Check that soo we can be sure that Ozmosis will run fine and that OSX installer will not fail in stage 2 of install process.
Without good bios that allow OSX writing to nvram we cannot use Ozmosis for instalation but only to boot installerd sistem.
This bootloader can load kexts from bios soo we can run OSX without any modifing of original apple store based installer.
All that are interesed in this bootloader need to mod own bios with windows based tools.
We will need MMTOOL 188.8.131.52 MMTool.zip for inserting,replacing and manipulating modules for this mod.
First of all we need make space in current firmware for succesfull mod.
1.)Check how many free space we have in firmware using mmtool.
We have 7kb free in this untouched original bios.
For making more space we can use UEFI BIOS updater becouse never files get seems smaller.
2.)For ozmosis without kexts we will need about 570kb free space.
If we wanna inject kexts then we need more.
3.)Easy way to make free pace in firmware its to compress COREDXE.
4.)Delete Filesystem driver from firmware becouse we will use enhanced one that works best with Ozmosis.
5.) Insert Ozmosis and needed drivers into firmware.
With this we can boot into OSX if we have fakesmc and needed drivers in S/L/E.
6.)Making needed kexts for ozmosis.
We will use script called Kext2Ffs by FredWsta and STLVNUB
Copy your kexts to kext folder,run script and u get .ffs for integrating into firmware.
U can integrate uncompressed and compressed.
If u wanna compress using MMTOOL u will save about 10% of space.
Soo if u really need space then compress using mmtool other way just use already compressed by script.
7.)Inserting kexts into firmware.
Now we just insert this into our firmware compressed.
8.)DSDT modifiyng by Fred
First you need to extract AmiBoardInfo from your bios with Coderush UEFITools.
Second use Dsdt2Bios to generate AmiBoardInfo.bin, replace with UEFITools in bios file.
Save file and it is ready to Flash.
9.) SSDT replace by fred
You can change SSDT tables directly in bios with UEFITool.
SSDT are in raw mode so clear, if you extract and save with .aml you can directly use them with MaciASL.
So to change in bios your must first find them and follow next screenshot.
Exemple for GA-Z77-DS3H
Now we can flash this onto our motherboard and test.
How to change smbios to macmini6,2?
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:BiosVersion=MM61.88Z.0106.B00.1208091121
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:ProductName=Macmini6,2
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:SystemSerial=xxxxxxxxxxxx
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:ProductFamily=Macmini
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:ProductId=Mac-F65AE981FFA204ED
xxxxxxxxxxxx=serial that need to be generated using clover comfigurator or chameleon wizard.
Or we can modify ozmosisdefaults with smbios data by using this kexttoffs
MMTOOL 184.108.40.206 MMTool.zip
QUO bios with ozmosis 167X files Z77MXQUOAOS.H2O.167X-MASS.zip
KexttoFfs Kext2Ffs.zip KextToFfs.command.zip
OzmosisDefaults with imac14,2 and boot arguments for OSX 10.10 OzmosisDefaults.zip
UEFITool can be found there
UEFI BIOS Updater here
Hope this will work for u.
