iAtkos V7 will not install HELPPPP

I installed it last year after a lot of messing and searching and putting codes like -v cpus=1 and so on. But now I cannot remember what codes I used to get it to work last time. Any help would be much appreciated.
Ok so I press f8 when the cd boots and if I dont type anything it flashes on the apple logo screen and then restarts immediately. if I type -v -f busratio=24 etc it will show some writing and then reboot immediately before i can read anything.

My MB is p7p55
CPU is i5 630 (i think)
RAM is 4gb
Graphics is Radeon HD 6750
I have 3 Sata hd drives and im trying to install to the 3rd drive.


Any ideas people??
Thanks

*EDITED* Just found that if i add 'arch=x86_64' it takes me to the apple logo screen but after a minute or 2 an error logo appears and stays that way until I shutdown.
