Load Region Jumper: The ARTIC186 8-Port PCI Adapter can be configured to operate in either of
two regions of memory: below 1 MB or above 1 MB. During power-on self-test (POST), the adapter
requests memory and other system resources.
The operating system being used determines which window is needed. For example, the DOS operating
system cannot directly access memory devices above 1 MB. On the other hand, operating systems, such
as Windows NT, operate in the protected mode and can access memory devices in the regions above
1 MB.
The following is JP1, the load-region jumper.
Window below 1 MB: The adapter requests memory resources below 1 MB. Use this setting if the computer is
operating in a DOS environment
Window above 1 MB: The adapter requests resources above 1 MB. Use this setting for operating systems that
operate in the protected mode (such as Windows NT).
