Thank you Fernando so much for your reply!!!! I used this: 64bit Intel RST AHCI & RAID driver v10.6.0.1002 WHQL to integrate with WIN XP x64 (from your link) then i selected: Intel® Desktop/Workstation/Server Express Chipset SATA AHCI Controller (this as text driver like you said) I also integrated the PnP driver: Intel chipset device INF files set v9.2.0.1030 WHQL for XP integration I think my memory sticks are ok because i can boot an evaluation copy of WIN 7 x32, but when i try to do it with a 64 bit OS i get the BsoD. Is there any information i can give you from the WIN 7 x32 i can boot from that might be of help? When i boot from WIN 7 x32 i can see the hard drive info, controillers, drivers etc. May be with that info you can help me modify the TXTSETUP.OEM file? Thank you so much!!! You are my last hope!!! Cheers!!!!
