freeze after chameleon

[justdoit]

hi guys,

my problem is this: when chameleon appears i select mac osx with -v and -x option and after this i see only 5 lines with the chameleon logo on background. it freezes as is and i don't know how to fix this.

my configuration is the following:

CPU: intel pentium 4 630

MB: msi 945PL Neo

video: nvidia geforce 9500gt 1gb

chipset: intel ich7 (or 5)
