| 36 | # Description: Contains the code that is copied into low memory (below 640K).\r | |
| 37 | # This code reflects interrupts 0x68-0x6f to interrupts 0x08-0x0f.\r | |
| 38 | # This template must be copied into low memory, and the IDT entries\r | |
| 39 | # 0x68-0x6F must be point to the low memory copy of this code. Each\r | |
| 40 | # entry is 4 bytes long, so IDT entries 0x68-0x6F can be easily\r | |
| 41 | # computed.\r | |
