Clover - Screen goes black after "DSMOS has arrived"

davidcmc · Oct 18, 2014

Hardware:
GigaByte H67MA-USB3-B3
Core i5 2400 (Sandy Bridge)
ALC899
RTL8111E
EVGA GeForce GTX 760

I'm using Clover 2953 and Yosemite installer in an USB drive (using the createinstallmedia method).

I try to boot the installer with verbose mode, and quickly after "DSMOS has arrived" message is shown, the screen goes all black. There's still activity (led keeps blinking) in the USB drive.

According to Clover wiki, this a typical situation that a video card couldn't be initialized.

I've tried almost everything.

Changed Intel Injection to NO. Changed Nvidia Injection to YES.
Changed ProductName (under SMBIOS) to iMac12,2 (Clover is pre-defining my system as iMac12,1).
Changed from HDMI to DVI port.

Tried with npci=0x2000 and npci=0x3000. Tried with PCIRootUID=1.
Tried with kext-dev-mode=1.

Nothing works. :think:

Same problem with Clover, same graphics card. Everything else is different.

You should not connect your video card when you're installing OSX, or use nv_disable=1 to avoid any problem. Connect your screen to your IGFX and use this to install everything. Then, you can try to install drivers.

I've used this video card fine with Mavericks installer, no injection needed.

I'm having the same problem as OP, but I don't have a graphics card. I'm only using and only intend to use the HD 4600 on my i7-4790K. What could be the problem in my case?

Have you tried choosing Yes or No in the Graphics Injection in config.plist?

Try cpus=2 I kept getting a endless reboot loop without it

I have it set to inject intel true. I might mention that I was not getting hd 4600 graphics injection through uni/multibeast either, no matter what I tried, so I was hoping clover would solve the issue. My hd5000kext is there, as well as me IntelAzulFramebuffer kext but neither is loading on boot. All UEFI settings check out. I posted a thread about my problem asking whether or not it could be a dud IGP on my i7. What do you think?

*edit*. So I thought it would be pointless to try the clover method on my HDTV since chimera/chameleon wouldn't work when trying to install with it...turns out I may have been wrong. I booted with clover into the installer in my HDTV with no flags, and there is no chugging and lagging indicative of graphics not being loaded. Crossing my fingers this works. Could this really have been a problem of DVI-I from my cintiq monitor? I'm fairly certain it's signal is all digital and no analog/VGA troubles should arise. This mobo only accepts DVI-I so if so I am going to need a DVI-I to hdmi converter. Really, nobody else has used a DVI-I monitor on the build I have and had this problem? That seems ludicrous.

Problem solved.

Turns out that Yosemite installer doesn't recognize my system SMBIOS correctly.
Main problem is that my system uses a GeForce GTX 760 and a Sandy Bridge Intel CPU.

By using iMac12,1 or iMac12,2 SMBIOS, the system assumes I have a Sandy Bridge CPU and some Radeon video card, which causes the problem.
If I select iMac13,2, the installer boots fine. That iMac generation has Ivy Bridge CPU and GeForce GTX 7xx (or 6xx, I don't remember exactly). So, the system recognizes my video card and boots fine.

So, I have two options of installing and using Yosemite.

1. Change ProductName (under SMBIOS dict) string to "iMac13,2" in Clover config.plist. This method allows me to boot the installer without any boot flag, but risks giving me power management problems, because the iMac13,2 SMBIOS makes OS X think that my CPU is an Ivy Bridge, when it's actually a Sandy Bridge CPU.

2. Boot installer with nv_disable=1 flag, install Yosemite and then boot the system without any flag. For some reason, after Yosemite is installer, it recognizes my system even though SMBIOS is set to iMac12,1. With this method, I just need to use nv_disable=1 flag to boot installer, and I don't have to change SMBIOS productname to iMac13,2, I can leave Clover default auto-detect (iMac12,1). After installation, Yosemite boots fine without SMBIOS change and boot flag.

I've chosen option 2.

Thats how I temporarily solved my No Signal to Monitor as well, but messed with my CPUPM until I was relieved with this response.
