I don't know about memory architecture of Compaq Armada 4120 laptop but machine setup says that system board has 16 MB and dimm slot 1 has 8 MB and dimm slot 2 has 8 MB memory module.
kcore size is 16781312
and "cat meminfo" produces a thing like this
total: used: free: shared: buffers: cached: Mem: 15245312 9936896 5308416 8876032 495616 5296128 Swap: 0 0 0 MemTotal: 14888 kB MemFree: 5184 kB MemShared: 8668 kB Buffers: 484 kB Cached: 5172 kB SwapTotal: 0 kB SwapFree: 0 kB
and Opti PCI chipsets 82c557, 82c558, 82c621
