The Intel IGM450 is most likely referring to a specific Intel graphics chipset or integrated graphics solution, typically used in older Intel systems. While there isn't a widely recognized IGM450 model specifically, it seems likely that it could be an error or shorthand referring to one of Intel's Intel Graphics Media Accelerator (GMA) series or integrated graphics, such as the Intel GMA 4500 or a similar model.

Assuming you're asking about an Intel GMA 4500 series chipset (which was popular in systems with Intel's older chipsets), this would be an integrated graphics driver that provides display functionality for systems using Intel's integrated graphics.
