(and any other modules in /boot/kernel) I didn't know the answer to the question - so I can show you a good way to start finding out sitting at a FreeBSD command line: $ man i915kms No manual entry for i915kms --- Always worth trying first $ apropos i915kms i915kms: nothing appropriate $ apropos i915 i915: nothing appropriate $ apropos kms drm-kms(7) - Kernel Mode-Setting drm-kms(7) - Kernel Mode-Setting $ man drm-kms --- Snip - go on read it at home So it seems this is a kernel interface for display adaptor mode settings - conclusion i915kms is the implmentation for the Intel 915 chipset. At this point if I really wanted to know more I'd probably go looking around the sources and/or ask detailed questions here or in a more focused list. -- Steve O'Hara-Smith
