# Procedure: InterruptRedirectionTemplate: Redirects interrupts 0x68-0x6F
#
# Input: None
#
# Output: None
#
# Prototype: VOID
# InterruptRedirectionTemplate (

#
# 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.
