| | 35 | ; Description: Contains the code that is copied into low memory (below 640K).\r |
| | 36 | ; This code reflects interrupts 0x68-0x6f to interrupts 0x08-0x0f.\r |
| | 37 | ; This template must be copied into low memory, and the IDT entries\r |
| | 38 | ; 0x68-0x6F must be point to the low memory copy of this code. Each\r |
| | 39 | ; entry is 4 bytes long, so IDT entries 0x68-0x6F can be easily \r |
| | 40 | ; computed.\r |
