+; 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.
