Setup Guide for Gigabyte BRIX and BRIX Pro using Clover

[headkaze]

how to fix this problem? hope can get help for this

Personally, I would just update to Yosemite. Read this post first if you decide to though.

just bought a Brix pro 4570R

after almost 10hrs of try and errors

finally it can output 4k@60hz(1080P retina scaled) via miniDP

thanks for you guys

Could you please post the patches you applied to achieve this?

Could you please post the patches you applied to achieve this?

at first, Download AMIBCP_aptio_4.53 (you can find it on google), HM85P.F6 bios
open AMIBCP.exe on windows, open the F6 bios on AMIBCP,
from the setup configuration tab,expand chipset>system agent configuration>graphics configuration
you can find DVMT Pre-Allocated on right window, change optimal from 32M to 64M
save, you may open it again from AMIBCP to check the change.

next, create a freedos bootable usb include the whole F6_BIOS folder DL from gigabyte website
remember to replace the bios file with changed one.

boot from freedos, type " AUFDOS.exe HM85P.F6 /gan "
(with "/gan" it let you to flash a bios without secure sign check, but also with risk to brick your brix)

after success update the bios, you may need to use HDMI to go through the installation
load optimal default, disable CFG lock, CSM enable,
boot from clover usb installer ( i use the config.plist you provide at page 9 #85)
install as the guide on the first post,
after install the clover bootloader, install the "pixel clock limit unlock" from #104
insert the below code to config.plist from #104

[COLOR=#000000]<dict>[/COLOR]
                <key>Name</key>
                <string>AppleIntelFramebufferAzul</string>
                <key>Find</key>
                <data>AwAiDQADAwMAAAACAAAwAQ==</data>
                <key>Replace</key>
                <data>AwAiDQADAwMAAAAEAAAAAw==</data>
                <key>Comment</key>
                <string>Increase buffer for 4K (64 MB RAM / 48 MB Framebuffer)</string> 

[COLOR=#000000]            </dict>[/COLOR]

also, loading the config.plist using clover configurator
from the graphics tab, tick Load Vbios, Patch Vbios, Inject Intel

(option: if dual boot windows, install windows using EFI windows usb installer create by rufus)

after all the installation
go back to bios, turn CSM to disable, turn off
plug in the miniDP cable to my LG 31MU97 monitor
boot to OSX, it just chagne to 4K@60hz automatically, and you can scale it
it max support 3840*2160@60hz, can't support C4K 4096*2160








this is how i install OSX and WIN10tp, not sure every single step is needed.
and this is my first time using clover as bootloader,
if don't turn CSM to disable after installation, i can't boot any OS from clover via miniDP connection (hdmi is fine)

akitohk: Thanks for your detailed explanation on how you got it working. It is very much appreciated.

boot from freedos, type " AUFDOS.exe HM85P.F6 /gan "
(with "/gan" it let you to flash a bios without secure sign check, but also with risk to brick your brix)

I used AMIBCP.exe (4.53) to edit my Gigabyte GB-BXi7-4770R BIOS (HM87P.F6). After applying the 64 MB change and flashing as suggested I did indeed "brick my brix"

Both KiAr and akitohk have successfully flashed a modified BIOS to their Gigabyte GB-BXi5-4570R machines. As far as I'm aware I'm the first to attempt this on a Gigabyte GB-BXi7-4770R.

I tried unplugging the CMOS battery for 15 minutes to reset the BIOS to default but it didn't help. Turning on the Brix no longer results in a signal to the monitor.

So I just want to reiterate what akitohk warned about in his post. It is very risky to flash an unsigned modified BIOS. Now I have to wait 2 to 3 weeks to get my unit back from Gigabyte. As least this can be a warning to others attempting this modification.

If someone does successfully apply and flash the 64 MB modification to HM87P.F6 please post the binary here.

If I save the Gigabyte GB-BXi5-4570R BIOS (HM85P.F6) using AMIBCP.exe and compare the original using WinDiff there are very few changes. Whereas if I save the Gigabyte GB-BXi7-4770R BIOS (HM87P.F6) using AMIBCP.exe and compare the original using WinDiff there are many more changes to the binary. I'm not sure why but it appears that AMIBCP.exe destroys the HM87P.F6 BIOS when you save.

Sorry to hear that,headkaze.

Recently flashed the bios with the 128MB option. Went well.
Really looks like AMIBCP doesn't like the i7 bios.

I used AMIBCP 4.55 and also added the /gan parameter to the flash.bat file. Then started the flash.bat from the USB DOS thumbdrive.

Have you tried the recovery for AMI Aptio Bios?

Rename the BIOS file to AMIBOOT.ROM, put it on a USB thumbdrive, insert into USB port.
Wait at least 15-20 min, or reset the CMOS if at all possible.
Power up and press CTRL + HOME
The BIOS may reflash from the BIOS file on the USB thumbdrive.

I just downloaded AMIBCP 4.55.0070 and it definitely results in a different binary than patching with AMIBCP 4.53. The question is anyone willing to give it a try on HM87P.F6?

Unfortunately I was not aware of this procedure at the time. My Brix is on its way to Gigabyte. It would certainly be interesting to know if it does work. It would also make the procedure a lot less risky until someone flashes an i7 successfully at least.

Hi, i'm trying to install Yosemite on a Brix with a celeron n2807 machine, but I'm unable to get it working. Installed BIOS is F7 and I'm using latest clover installer available but after the boot menu from my USB installer unit I can only see the white Apple on black background and nothing more. I've tried with verbose mode and it hangs after the uuid message. Can anyone give some tips?

Did you disable "Cfg Lock" in the BIOS?

 

[fidoboy]

There is no such option in my BIOS. I'm using latest version available, that it is F7. When using clover from my USB bootable pen drive, last displayed message, in verbose mode is `root device uuid is....[some number here]` and then many plus symbols. Same USB boots fine in other machine but not with my Gigabyte Brix. I've two Brix machines, both with same result...
