Figure 3-3. Setting the Base Address
Table 3-1 lists I/O addresses commonly used by IBM PC/XT, AT, and
compatible computers. Determine an even boundary of eight I/O
addresses within the range of 000H to 3F8H that is not being used by
another resource in your system (including another DAS-800 Series
board), and set the switches to the appropriate base address.
