  Note: Set the switches to the total amount of system memory installed
  not including this card. This enables this card to start filling system
  memory where the other card(s) left off. A setting of 4MB or less means
  that this card is the first memory card to be installed. A setting of
  more than 4MB means that this card is the second memory card that is
  installed.
