+; Procedure:    InterruptRedirectionTemplate: Redirects interrupts 0x68-0x6F
+;
+; Input:        None
+;
+; Output:       None
+;
+; Prototype:    VOID

+;                                VOID

+;
+; Description:  Contains the code that is copied into low memory (below 640K).
+;               This code reflects interrupts 0x68-0x6f to interrupts 0x08-0x0f.
+;               This template must be copied into low memory, and the IDT entries
+;               0x68-0x6F must be point to the low memory copy of this code.  Each
+;               entry is 4 bytes long, so IDT entries 0x68-0x6F can be easily
+;               computed.
