I/O Memory Map
Table 6 provides a map of memory addresses reserved by the computer for peripheral input/output (I/O) devices. Use the information in Table 6 to
determine if the memory address of an external device (such as a PC Card) conflicts with a memory address reserved by the computer.
Check the documentation of the external I/O device to determine its memory address. If a device's memory address conflicts with a memory
address reserved by the computer, change the address of the device.
