[SOLVED] Enable Nvidia AGP Fast Writes и Side Band Addressing

http://ubuntuforums.org – I need to write this article after reading http://ubuntuforums.org/showthread.php?t=140989 It's not actual for hardy, jaunty and later ubuntu versions that use dkms for build kernel module. My OS is Ubuntu Jaunty 9.04 OK First of all: Code: cat /proc/driver/nvidia/agp/* Fast Writes:    Supported SBA:            Not Supported AGP Rates:      4x 2x 1x Registers:      0x1f000017:0x1f000114 Host Bridge:    PCI device 8086:2570 Fast Writes:    Supported SBA:            Supported AGP Rates:      4x 2x 1x Registers:      0x1f004217:0x00000114 Status:          Enabled Driver:          AGPGART AGP Rate:        4x Fast Writes:    Disabled SBA:            Disabled So FW are supported, FW is Disabled. Now you should stop your desktop manager and use tty console. Code: dkms status nvidia, 96.43.10, 2.6.28-15-generic, i686: installed (original_module exists) Code: sudo dkms uninstall -m nvidia -u 96.43.10 Code: sudo rm -r /var/lib/dkms/nvidia/kernel Code: sudo rm -r /var/lib/dkms/nvidia/96.43.10/2.6.* Code: sudo rm -r /var/lib/dkms/nvidia/96.43.10/build/ Code: sudo nano /var/lib/dkms/nvidia/96.43.10/source/os-registry.c find (use Ctrl+W) "agpfw" and "agpsba" if SBA supported in your card replace Code: static int NVreg_EnableAGPSBA = 0; with Code: static int NVreg_EnableAGPSBA = 1; and Code: static int NVreg_EnableAGPFW = 0; with Code: static int NVreg_EnableAGPFW = 1; than Code: sudo dkms build -m nvidia -u 96.43.10 Code: sudo dkms install -m nvidia -u 96.43.10 now Code: cat /proc/driver/nvidia/agp/* Fast Writes:    Supported SBA:            Not Supported AGP Rates:      4x 2x 1x Registers:      0x1f000017:0x1f000114 Host Bridge:    PCI device 8086:2570 Fast Writes:    Supported SBA:            Supported AGP Rates:      4x 2x 1x Registers:      0x1f004217:0x00000114 Status:          Enabled Driver:          AGPGART AGP Rate:        4x Fast Writes:    Enabled SBA:            Disabled (Hardware)
