Dell Precision T7400 Install issue

[sjd1869]

Dear List

 

I have been trying to build a Hackintosh on my Dell Precision t7400 Hardware for a couple of days now using various

darwin boot isos and i have managed to get the boot disk to find the Leopard Retail DVD

 

I then get the Grey Apple Splash screen but eventually I see a No Entry Sign appear on the Splash screen and the install

goes no further

 

can anyone help me out as I really want to get Leopard running on this HWare

 

Thanks

 

S
