[SOLVED] How to unlock BIOS options of rebranded TONGFANG chassis systems?

Sleep working fine for me on both the stock Windows 10 and MacOS Mojave 10.14.3. Suspend works fine in windows 10 but does not work on a Mac Clone very well. No keyboard loss, I’ll test again but I don’t see this issue.

If you lose keyboard plug in a USB keyboard to shutdown properly, otherwise you will eventually corrupt data/OS.

Thanks @pcfr33k - is that with the above settings that @Fan mentioned being applied too?



I’ll check again tonight

I’ve only used those settings in Linux, did not test in Windows. But I don’t know how it would be any different. So resuming in Windows with dGFX off results in keyboard not working? I only heard of touchpad not coming back in Linux (whose fix is to force unload / load of the i2c_hid module before and after sleep via systemd files).

@pcfr33k how does hackintosh work on here? Are you using it with dGFX on or off?

It works as good if not better than windows all my PCs and laptops at home have MacOS so I am a freak when it comes to that. It runs perfectly and I can share all you need to get it up and dual boot. No need to turn anything off in Bios just run a Clover script to disable dGfx. Actually it can’t work better than windows since both GFX cards work hand in hand in windows.

Its fast and runs all the MacOS apps perfectly. I grabbed a samsung 970 NvMe 250Gb from Microcenter and added that to the second controller and it works so good!! You can also just replace the hard drive with an SSD and install MacOS there to. Will also need to replace WIFI card which will work in windows and MacOS but have to check if it works OOB in Linux.

Only 1 issue when it sleeps then wakes, then shutdown from Apple logo then shutdown, there is snow on the screen, so have to push to the power button once to shutdown. just one minor catch for both the 15 and 17 inch but my friend said his 15 inch version MacOS misinterprets the LCD size as 21 inch instead of 15 inch. Mine is correctly seen as 17 inch.

You can do a lot of things in MacOS similar to what you can do in linux except configure/compile a linux kernel. :slight_smile:



@Fan

I am able to reproduce this issue in windows 10 but not MacOS but thats because dGFX is disabled in my MacOS so that explains why I said I did not see the issue. So yes these settings cause the keyboard to disconnect for some unknown reason. I did not make any changes to PEG since you were not specific as to exactly what you disabled there but it doesn’t matter because like I said I also can reproduce the issue in windows with all the settings @Fan posted except no changes in PEG and not even sure what the point is in disabling anything there anyhow.

Thanke you for telling me this issue is not only mine.
I tried so many settings even remove the nvidia drive, but it was never help.
So I will try whether this issue reproduce in ArchLinux later.

Thanks @pcfr33k and @nimaim - can you repost or link that script for @Fan to try, instead of him disabling dGFX in BIOS, maybe that method would work better for his purposes once he sees how it works.
When you do, also tell him what he needs to set (reset) back on the BIOS settings vs what he was setting before, thanks!



With no LCD signal and still able to boot, use link below to get back up and running:

To use your USB boot backup to autoflash rom with no LCD signal but forgot to enable CSM, enable CSM blindly first:

Important Notes, if you are going to flash your Bios the blind way, you must enable CSM or that method will not work, and if CSM was not enabled see one of the above links to blindly set it. DO NOT set a Bios password if you did remove it now while testing BIOS settings.


Lastly before attempting any changes in this Mod Bios make sure you have the CH programmer mentioned throughout these posts in order to flash your CH Bios Backup dump as a last resort if none of the methods above work. The CH Programmer and all tools needed is mentioned in the final guide.

If you simply just want to restore back to default and no issues with LCD signal then go into the exit and save menu (last menu) scroll down 6 times to restore, then go back up and save.

Does this allow disabling HT?

@ditchmagnet - yes, @ Advanced 2 >> CPU Config >> Hyper-threading

Yes, you can close it in advance2 >> cpu configuration >> hyper–threading

does any one has the bios of gj5cn6e ? I have in my system 102 but do read here about 104 or even 108.
Just orginal will be fine.

thx

@pcfr33k - can you please write method for AFU blind recovery for @Pear - he does not have FPT backup, so needs to recover via AFU so he doesn’t loose board specific details.
Unsure about CSM setting, so maybe include with and without that set instructions too, if you don’t mind, thanks!
Here’s a link to his stock BIOS package for your reference, and so you can check the stock batch file/folder contents etc - https://www.mysn.de/driver/1_XMG/XMG_NEO…BIOS_N.1.09.zip

I’m going to redo the guide tonight and make a bold warning about changing display options, I’ll include your recover methods linked above, and if you have any other info/comments I should add please let me know and I’ll put them there and quote you if you don’t mind.
Stuff like this works, this doesn’t, you need to use this (Linked) script to do this, etc.



Here are some links that might be helpful but I have no guide unless a FPT backup was done. There are guides to get the details back into the Bios such as UUID etc but I don’t have links to them.

Does his PC still boot but just to black screen if so he can follow one of the links below to reset his Bios blindly. If he cannot boot at all that is a big problem not much help I can provide. I don’t have a guide for AFU only FPT below.

Thanks @pcfr33k - Yes, I know how to put details back, but only if we have the details Wouldn’t your method be able to be used with AFU batch same as FPT, just running different commands, that’s what I was assuming you could do for him?
Batch you make to launch the AFU Batch instead of FPT batch, reboot command is already in AFU switches. Or just really how to blind run that AFU batch should be plenty enough to sort that out I would imagine (laid down for him in laymans terms, including getting the files onto USB properly etc).

Yes, just black screen due to graphic option changes. He already tried clearing CMOS, which should reset it I would think, but maybe he didn’t do long enough? @Pear - follow link above to reset BIOS to defaults blind, you want “With no LCD signal and still able to boot” links to post 253 (Kinda , that’s the one you want)



Yes the one that says 8 across and 6 down, that will reset your bios. Follow those instructions you will be back up and running. Never thought about it but in theory AFU would work the same but remember AFU DOS doesn’t work for Aptio v5 so I doubt the procedure will work for AFU, well it didn’t work when I tried.

Thanks @pcfr33k There is AFU.EFI he could use, but you’d have to familiarize yourself with using that and booting to EFI before you could help him figure that one out. You are correct, I forgot about that with AFU and DOS, there is no DOS version there either of course, just those cursed GUI and CMD line ones.
I have AFU DOS for aptio V, but unsure if I ever sent any to you for you to check to see which if any worked? Do you want to try now and see if any will work for you in DOS and flash a stock BIOS, or are you sure he can reset BIOS with 8 across 6 down thing (CSM enable/disable doesn’t matter)?

@Pear - see above, you should be able to re-load optimal defaults blindly, it may take you a few tries but I think you’ll get it, I’ve seen a few users here do it in your same situation.




To reset is all he will need to do if its just boot to black screen. It would be interesting to try the EFI AFU as long as he is just flashing the vendor stock bios that would work to. Don’t have time now to test but he can google search how to create an EFI boot and auto run AFU, wouldn’t he need to get the correct ME package and would need to know the ME version of his MB. I won’t have time for a while validating a new LIS for my Job. If I have time to spare I can give this a try but for now he needs to try and reset the Bios.
