915resolution is a tool to modify the video BIOS of the 800 and 900 series Intel graphics chipsets. This includes the 845G, 855G, and 865G chipsets, as well as 915G, 915GM, and 945G chipsets. This modification is neccessary to allow the display of certain graphics resolutions for an Xorg or XFree86 graphics server. 915resolution's modifications of the BIOS are transient. There is no risk of permanent modification of the BIOS. This also means that 915resolution must be run every time the computer boots in order for it's changes to take effect. 915resolution is derived from the tool 855resolution. However, the code differs substantially. 915resolution's code base is much simpler. 915resolution also allows the modification of bits per pixel.
