  Note:The boot ROM socket can contain a BIA ROM or a boot ROM. The BIA
  ROM provides the node address if a boot ROM is not installed. If the
  ROM memory is disabled, the node address must be set using the
  RTR16ASI.SYS device driver.

  replace it with the boot ROM.

  JP3 must be closed for the boot ROM to function.

  Note:LLC allows the card to access networks using the ISO and SNA
  protocols. (e.g. IBM PC LAN,IBM 3270 terminal emulation, and AS400)

  The card has built-in LLC support on the two ROMs above SW1. To allow
  for future compatiblity and upgrades you can load the LLC code into the
  onboard RAM.

  Note:If the MAU type is set to 802.2J (JP2 - Pins 2 & 3 closed) LED1
  will not light until the adapter attempts insertion into the network.
