Some older models of the AT-2450FTX, AT-2700FTX, and AT-2745FX
Series cards have a DIP switch you need to set if you install the optional
BootPROM chip. If your network adapter card has the switch, you must set
it to reflect the active port or speed of the adapter. The possible settings
are given in the following tables.
