Devices used and potential conflicts |
| 0 | This IRQ is used within the system board for system timing. If a conflict arises with this IRQ chances are the system board is bad, use a diagnostic program to determine if this is the case. |
| 1 | This IRQ is assigned to the keyboard. Its never available to other add-in cards. Again if this is the problem, its most likely a problem with the system board. |
| 2 | This IRQ was assigned to older EGA video cards. Beware, IRQ 9 uses IRQ to communicate with the CPU, therefore this IRQ should only be used under extreme circumstances. |
| 3 | This IRQ is assigned to the serial ports: COM 2, and COM 4. Avoid setting other devices to this IRQ since mice, modems, and other devices are set to use this IRQ. |
