[HELP] What to do at this situation?

[Vinnicius]

I'm trying to install the Mountain Lion on my notebook Acer Aspire 5750 / 5750G. The installer just boots when the kexts AppleIntelHD* and AppleIntelSNB* (or something) are deleted from S/L/E, and boot to installer with -x -v PciRoot=1 GraphicsEnabler=No

 

After install boots only with PciRoot=1.

 

Feedback after install:

 

Sound: No

Video: Only 1024x768, recognized only 64MB, slow speed.

Webcam: Yes

Microphone: No

Battery: No

USB: Yes

Wi-Fi: No

Ethernet, SD Card, HDMI, VGA, disk burner: Don't tested yet

One more thing:

 

I updated the BIOS to version 1.20. I don't know if this will help.
