What installation are you referring to? OS X?

If you can, please do a detailed step by step installation so that newbies can follow. And please mind your punctuations (you're missing out the commas) so people will understand you better.

Ok first of all sorry for my english because it is a bit rusty.
1- install osX Lion (wich method do you want....I installed a clean Osx Lion 10.7.2 with unibeast method + rBot(cd needed after the install to boot in your OSx)->after the fresh install my resolution is default 1024x768
2- install Multibeast 4.2.1 if you don't have dsdt.aml created by you for your motherboard then don't install Multibeast only download Chameleon latest version and install it on your installed partition of Lion or what osx you have installed plus install the Champlist
3- after correct install of Chameleon and Champlist you can eject the rBoot CD because you will not need it again it will boot from your Lion Partition
4- Now open Champlist and see if it had have installed correctly and go to Configurations and there you should mark as Ok the following for your Ati Driver I have AMD Radeon HD6550m to be clear GraphicsEnabler=yes and Ati Framebuffer=Duckweed save it to your boot chameleon plist found in extra folder on Lion partition and that is all
5- I have also optional selected Use Kernel cache=yes ,npci=0x2000=yes ,darkwake=0=yes and restart fix=yes and that is all and father the restart my AMD Radeon HD 6550M is on and it has the 1024 mb of ram ddr3 etc
The only thing what doesn't work fir me is audio driver I didn't find one what works for audio driver I have ALC272x so If you can make it work please pm back and I hope that this will work for you video card as well as it did for me.(PS if at boot you screen is tearing then restart and boot with -x command or GraphicsEnabler=no and change the frame buffer in Champlist as it may differ from mine)
