driver install failed with error "NVRM: BAR1 is 0M" on GA100, ubuntu1804/1604


when i try to install the driver on GA100, it is failed with below; i am not sure if any other setting on the bios is needed(4G above decode is enable); thanks your suggestions;

ERROR: Unable to load the kernel module ‘nvidia.ko’. This happens most frequently when this kernel module was built against the wrong or improperly configured kernel sources, with a version of gcc that differs from the one used to build the target kernel, or if another driver, such as nouveau, is present and prevents the NVIDIA kernel module from obtaining ownership of the NVIDIA GPU(s), or no NVIDIA GPU installed in this system is supported by this NVIDIA Linux graphics driver release.

Please see the log entries ‘Kernel module load error’ and ‘Kernel messages’ at the end of the file ‘/var/log/nvidia-installer.log’ for more information.

nouveau module is not loaded(checked by “lsmod |grep nouveau”, no output)
thanks your help first

If you already enabled above 4G decoding, then there’s something wrong with the bios. Please attach a complete dmesg from a fresh boot.
What kind of server/board model are you running?
