[piterkater]

Hello!

I have and Acer Aspire 5471G with:

Intel Core i3-330M

Motherboard HM55.

Graphic ATI Mobility Radeon HD 5470 512Mb VGA HDMI output

Screen Monitor 15,6" HD (1366x768)

Clover boot

QE/CI not work on Yosemite, system very slow. Same Clover "config.plist" work OK on Mavericks with settings like this:

 

....
<key>Graphics</key>
<dict>
	<key>CustomEDID</key>
	<data>

</dict>
....

 

I tested @artur-pt sugestion for config.plist but not work on Mavericks or Yosemite:

 

.....
<key>Graphics</key>
<dict>
	<key>InjectATI</key>
	<true/>
	<key>InjectEDID</key>
	<true/>
	<key>LoadVBios</key>
	<true/>
	<key>FBName</key>
	<string>Langur</string>
</dict>
.....

 

Add a link with my current Clover files(Not all files), DSDT.aml, AIDA64 html report and IORegistryExplorer dump.

I hope any help with this. One week later I can´t go on.
