Sorry, the graphic card was written on official Dell page but I guess it's for newer models. Checking Hardware ID through Windows: PCI\VEN_8086&DEV_0A06&SUBSYS_06511028 I get this results:
Intel® HD Graphics
No specific model? Which is strange.
Anyway:

Any tips? Thanks!
btw. one year ago I made a successful hackintosh on Aspire 5741g using Clover and QE/CI injection.
