Currently only P4M900 chipset motherboard's on-board VGA will support Vista Basic version. Other VIA on-board VGA will not be able to support Vista. You will need to install an AGP or PCI-E VGA card support DirectX 9 to support Vista's basic function. If need to support Vista Aero in Premium version, it requires DirectX 9, Pixel Shader 2.0, and 128 MB VGA card memory to support Aero function.
