Installed Niresh ok, now black screen at boot

Hi All, I have made a few hackintosh machines previously running SL & ML but am getting stuck now trying to do it on a Compq CQ56-104SA.


This is a bit more of a challenge due to the spec of it I think:

2.3 GHz AMD V-Series Processor V140

ATI Mobility Radeon HD 4250 Graphics


So from my Macbook I downloaded made a USB key image of Niresh 10.8.2.

I booted that using the AMD kernel and installed it... and it got to the end, then I rebooted but all I am getting is a black screen.


I am having to use GraphicsEnabler=No otherwise I get an error:

Memory allocation error! Addr:0xdeadbeef, Size: 0x0, File ati.c Line: 1619

This is a non recoverable error! System HALTED!!!




I am now trying to boot using these flags: GraphicsEnabler=No cpus=1 -x


This will show a brief text display about a bootstrap patch and then the screen goes black.


The machine is still doing things as I can hear the hard disk running, then after a while it starts to stop and start the disk a bit more and then the fans increase so I think it is still loading and running things just not showing anything on the screen.


Does anyone have any ideas I can try? Obviously the screen was working fine through the installation.

Niresh's installers will put back the original mach_kernel, thus making your machine unable to boot.
You need to use a tool like partedmagic to put back the modded/patched kernel of your choice inside your drive after installation.
Also, pay attention with "niresh" torrents...
I ran malwarebytes and there was malware inside plus funky x509 certificates...
Get OSX from the apple store and make your own installer. Safe and Legal.
