Need help to install Snow Leopard on Presario CQ60 202EL

[Agfev]

Hi everybody! I'm Agfev and 'im very happy to talk with you about mac and hackintosh.
Well,this is my situation:
I've bought an USED Compaq Presario CQ60 202EL for 90 euros. The man who sold me this laptop,told me that the hdd was replaced with an other one.
Now,searching on web i found out that is necessary the SATA hdd and change the SATA Mode on AHCI;as i said before the hdd was remplaced with another one that i discovered it's an ATA hdd and so i can't install Snow Leopard Hazard version.

Furthermore,i found a guy that was installing Leopard on a CQ60 120EL,that is older than my CQ60 202EL.

My question is: Is it necessary ONLY a SATA hdd or something more?
