Thread: OS X starts OK from iBoot but get stuck when starting from Chameleon

I have a double boot Windows 7 and OS X 10.6.6 on an MBR partitionned disk
I have installed Chameleon 2.1 svn1768. to choose the booting system. Windows starts without trouble.
My problem is with OS X getting stuck when starting from Chameleon . In verbose mode I can see the access to the system extension folder then the system crash. I have tried changing options in the chameleon.boot.plist. I can see these options being taken into accounts but it does not make any difference.
When I boot the same OS X system with iBoot there is no problem at all to boot and run.
As anybody experience some similar problems or has anybody any clues on how to fix this starting problem ?
Many thanks in advance for any help.
Running on an HP 630 notebook

I can boot successfully via boot think ,but can't via chameleon. I also don't know , someone told that it was the dsdt's fault,the dsdt had mistakes.
