+* Description:  Test program to check the ability to manipulate the
+*               BIOS data area from protected mode using the PM
+*               library. Compile and link with the appropriate command
+*               line for your DOS extender.
+*
+*               Functions tested:   PM_getBIOSSelector()
+*                                   PM_getLong()
+*                                   PM_getByte()
+*                                   PM_getWord()
