FOOTNOTES [Δ]
  1. Attained via one 2Rx8 128MB EDO 60ns non-parity unbuffered SO-DIMM, might not be possible with 1Rx8 128MB EDO SO-DIMMs.
  2. Attained via two 2Rx8 128MB EDO 60ns non-parity unbuffered SO-DIMM, also possible (770 only) with 1Rx8 128MB EDO SO-DIMMs.
  3. Attained via one 1Rx8 64MB EDO 60ns non-parity unbuffered SO-DIMM and one 1Rx16 32MB EDO 60ns non-parity unbuffered SO-DIMM, along with 8MB of BGA memory on the motherboard. The extra 8MB that is located on the daughterboard is disabled with this configuration.
