Like i said IDK what to really do next.Im guessing i have to get an EFI string or a kext or whatever else for the video and add said files to the chameleon boot CD.but i dont know how to get said strings/kexts or where to put them on the CD or what to do with them. My HP Probook specs: Core2Duo 2.53Ghz, 4gigs ram, 500gigHDD, ATI Mobility 3400, card reader, built in webcam etc. Im confused as to what to do next.i have a 10.5.7 or somthing 'live DVD' that i can get to install to an external USB HDD.but the 'live' method refuses to load correctly on any of the PCs in the house.and i have no access to another working Mac. it stops with a white/gray screen with nothing on it.wich i guess means the video chipset aint supporeted.or something. I got kernel panics when i first tryed it (im assuming thats what the little no-smoking sign thing and the 'restart your computer by pressing blah blah.' box means happened, and then i tweaked the BIOS settings and i can get a little further now, but still not to the installer. I have not modified the ISO at all.just burned and booted. Im using the Chameleon Install ISO discussed in this thread: (the first link). I have successfully gotten the Retail physical install DVD of Snow Leotard to boot up to a certen extent. I too have an HP Probook, mine is the 4710s.

I see it has been a few weeks since anybody said anything in this thread.
