It's due to larger vbios on 7xxx cards. It cause a bunch of alien looking text after Boot0:Done. Newest Chameleon helps for some, but for me the only way to get past this was to install Chameleon/Clover onto a mbr formatted drive instead of guid. I used a USB when first testing to get it working. Once you get past that, your next problem will be booting to a blank screen, the trick to get past this is to sleep and wake the computer. If you have automatic login enabled, disable it so you don't have to wait for all the desktop stuff to load before you can sleep and make screen work. Also make sure sleep works with your 5770 first so you know your system can sleep/wake. I had a 5770 I had to switch back to a few times while figuring all this stuff out
May I ask what's the difference of installing them to MBR disk and GUID disk?
I've got GraphicsEnabler = YES but if I throw in NVDAResman, it stucks at "NVEnabler::Probe fails"
I can't get resolution working, other than GraphicsMode.
I don't have EFI String in my Chameleon plist.
I am using GeForce 9200M GS on HP Compaq CQ45-101TX.
