I/O Memory Map
provides a map of memory addresses reserved by the system for peripheral I/O devices. Use the information in Table 6 to
determine if the memory address of an external peripheral (such as a PC Card) conflicts with a memory address reserved by the
system.
Check the documentation of the external I/O device to determine its memory address. If there is a conflict with a memory address
reserved by the system, change the address of the device.
NOTE: To view I/O addresses in Windows 95 and Windows 98, click the
Start
button, point to
Settings
, and click
Control
Panel
. Double-click the
System
icon. Click the
Device Manager
tab, and then double-click
