I'm not sure which one it claims to need as none seems to match the name exactly. Here is a way to search tho. When you type in make menuconfig and it comes up, hit the / key. That would the the question mark WITHOUT pressing the shift key. Type in IOMMU and hit return. From there you can scroll though with the arrow keys to find out which one you think fits. This si my results: root@fireball /usr/src/linux-3.0.3-gentoo # cat .config | grep IOMMU CONFIG_GART_IOMMU=y # CONFIG_CALGARY_IOMMU is not set CONFIG_AMD_IOMMU=y # CONFIG_AMD_IOMMU_STATS is not set CONFIG_IOMMU_HELPER=y CONFIG_IOMMU_API=y # CONFIG_IOMMU_DEBUG is not set # CONFIG_IOMMU_STRESS is not set root@fireball Yours looks the same as mine so not sure what to suggest other then the search above. Maybe you are Intel based where I am AMD based? Hope that helps. Dale :-) :-)
