If you have a mac book, you could even create a USB boot drive that is specific for your system
before you even install OS X. A key component in this is the DSDT file. The errors you got with the DVD's seem quite "random" (I mean to say I don't think they are related to OS X itself, they'r probably BIOS settings or hardware problems. A "easy" check is to burn some Linux distro live CD, and try to boot it. If it does boot, then it means that OS X
should boot on that hardware. This doesn't cover BIOS settings thou, since Linux is less restrictive than OS X on that front.
What have you set in your BIOS? Can you post a shot of every screen?
If it could help you, I can post a image of my most current USB drive -which I haven't used for a while, but should work anyways- so that you can know what the problem is (meaning if it is related to Chameleon).
I seem to remember I had that EBIOS read error when I tried to use a DVD-DL OS X DVD on a single layer IDE drive. At the moment I thought maybe it meant that OS X couldn't continue to load from that drive since later on it can't read it (my IDE drives don't work).
Hey, here is a zip file (I recently noticed that disc images aren't better since they don't copy boot0 and boot1h they don't serve there purpose -and maybe that is why UnRetroGamer didn't get anywhere

, sorry I'm new at this too), so once you have installed boot0 and boot1h, then just extract this zip onto your drive.
Why is the archive in a 7z, inside a .zip ? Because a plain old ZIP was 1.50MB and that's the limit for infinitemac (it was probably 500B over or something crazy like that!). So use peazip or something to extract it.
