Hi, Lawson.
Video **cards** have their own memory (always, in my experience), but
motherboards with **onboard** video come in two flavors -- some have
dedicated video RAM, and others "steal" video memory from the first DIMM.
Having recently had the good fortune to acquire some motherboards that
aren't antiques, I now have both kinds here. Someone using the "steal DIMM
RAM" type with the mem= line needs to be careful, since claiming more memory
than you have is a system killer, and Linux sees memory after the video
chunk is removed.
