hi,there My computer has installed intel core dual i3-530 cpu that is newly announced by intel corporation. i3-530 has a special integrated graphic card , it means that you needn't extra graphic card in your computer if i3-530 is used. You can find lots of information about i3-530 on line. After SLC5 OS is installed, I find that graphic resolution (800x600)is poor and can't be altered. I want to know what is matter with it. look forward to reply. -- Mr.Ying-Hua Pan Department of Physics Harbin Institute of Technology Harbin, Helongjiang Province, 150001 P. R.
