I believe ICS merged with IDT in 2005. I checked their website but failed to find any support for video chipsets.
Have you checked Intel website or try Everest Home Edition software?
To find make and model of pc hardware, EVEREST Home Edition is a free system diagnostics, system information program that will id most hardware onboard a mb. as well as the actual motherboard.
Alternate Everest download link: (offers 2 sites to dl program from)
Run the program and then:
Click on Computer
Click on Summary
Right hand window (hardware) if the text is blue
this is a link to the web site for that particular hardware.
If you need additional help, please post a SUMMARY report from Everest.
