915resolution
Summary : 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 necessary 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 inorder for it's changes to take effect.
This is not installed by default.
