System dies at login screen before actual login

[spakk]

\Extra\DSDT.aml Should be /Extra/DSDT.aml

 

Also for Enoch to load the ROM it should be named, 10de_1380.rom

absolutely correct, a typo with great impact...I was today in many weddings and messes up the things :-((

[ylluxiun]

So here's where I'm at right now:

 

org.chameleon.Boot.plist contains:

Aaaaand.... What on earth, I'm still getting the "Memory allocation error!" line in Chameleon!

[spakk]

when once again the error message "Memory allocation error" appears, then remove the folder  /modules/  in Extra

[ylluxiun]

I do not have `/modules/` in /Extra...  Please see last listing of the directory in previous message.

[Shaneee]

If you still get the error. Restore your original Extra folder but take the ROM and add it to the original folder and add the UseNvidiaRom=Yes at boot. Note it is case sensitive. 

[ylluxiun]

Well, something new here... After the login screen appears, I now get a brown (orange-brown) screen instead of black when the system hangs:

I am using my old Extra folder + the two settings:

        <key>UseNvidiaROM</key>
        <string>Yes</string>
        <key>VBIOS</key>
        <string>Yes</string>

And with the `10de_1380.rom` present in /Extra.

[Shaneee]

Do you see it loading the ROM during the first Enoch screen like when we tried with the other nvidia card? 

 

Try with GraphicsEnabler=Yes nvda_drv=0 and see what System Information says if it boots.

[ylluxiun]

No, I don't see it:

[Shaneee]

Maybe the ROM is case sensitive too, 10DE_1380.ROM

 

Also try typing the bootflag. If still doesn't load it remove the VBIOS flag.

[ylluxiun]

Renamed, 10DE_1380.ROM, result:

Same result with no VBIOS flag:

[Shaneee]

Well that's strange. Remove the flag from the boot.plist and type it manually.

So I removed the setting from boot.plist and set it manually at boot, here is Chameleon output:

 

 

And here we can see what the kernel is seeing for the boot args:

[Shaneee]

Remove this,

 

UseNvidiaROM
Yes

 

And at boot type it. UseNvidiaROM=Yes

[ylluxiun]

Yes, I did that as per the appended last message.  The result of that is the last two photos of the last message (eg, I showed the args to verify that it was postfixed when I manually defined "UseNvidiaROM=Yes".

Sorry, InsanelyMac get's kind of confusing sometimes in that it affixes new messages to the last message if there has been no reply...

[Shaneee]

The forum merges double posts automatically

 

Not sure at all why the ROM isn't being loaded. You could flash but that is entirely up to you as I'm sure you are aware of the risks.

[ylluxiun]

Yeah, I just would like to know how @spakk got this new rom and how he's sure it's the right one compared to the other.  I have *NO* problem flashing it at all, just like to know more about it before taking the plunge...

[Shaneee]

The ROM he uploaded is for the 2GB GTX 750 Ti

[ylluxiun]

Alright, so quick thought:  10de_0ca3.rom was for the first video card we tried... Would this new BIOS not have a different filename?  Anyway, going to go ahead and flash this booger here...

[Shaneee]

10DE is the nVidia Vendor ID and the second lot is the device ID. Enoch wasn't even looking for the VBIOS which was weird.

[ylluxiun]

So I've flashed the video bios to the one @spakk noted.  I am back to getting no signal (monitor goes to sleep) when the login should appear.  

[Shaneee]

But still boots with nv_disable?

 

Edit: You could also test these two, https://www.techpowerup.com/vgabios/167660/evga-gtx750ti-2048-140825 https://www.techpowerup.com/vgabios/163978/msi-gtx750ti-2048-140424

[ylluxiun]

I also just tried @spakk's /Extra and tried to load DSDT again, but it would not load and I got the same result.  When the monitor goes to sleep / no signal from the video card, I CAN ssh in still so sshd is NOT hung and thus the system is not hung anymore... so that's a good thing I suppose, but it's essentially back at square 1 with this card.

 

`nv_disable=1` DOES still work...

Regarding those last two bios versions (EVGA & MSI), is there a potential advantage of one over the other?  The previous BIOS version I used was from the forum and supposedly was to work for my card on OS X.

[ylluxiun]

Wow, well I went to go try the other two BIOS you threw up there, but lo and behold, now nvflash is crapping out on me!

C:\nvflash_5.292.0>nvflash.exe -r

NVIDIA Firmware Update Utility (Version 5.292.0)
Simplified Version For OEM Only


ERROR:  The flasher cannot automatic disable the NV driver on Windows x64,
        please use the flasher 64-bit version instead.

Ever see anything like that before?  I'm shooting blanks trying to hunt it down and resolve. Insane.

[Shaneee]

Use this version, https://www.techpowerup.com/downloads/1824/nvflash-5-95-0-1-for-windows

[ylluxiun]

I installed a fresh copy of Windows and nvflash didn't throw that error, but I did get "ERROR: GPU mismatch" on both of those roms you posted, so I guess those two are no goes.
