| 18 | Description |
| 19 | ----------- |
| 20 | |
| 21 | The LM83 is a digital temperature sensor. It senses its own temperature as |
| 22 | well as the temperature of up to three external diodes. The LM82 is |
| 23 | a stripped down version of the LM83 that only supports one external diode. |
| 24 | Both are compatible with many other devices such as the LM84 and all |
| 25 | other ADM1021 clones. The main difference between the LM83 and the LM84 |
| 26 | in that the later can only sense the temperature of one external diode. |
| 27 | |
| 28 | Using the adm1021 driver for a LM83 should work, but only two temperatures |
| 29 | will be reported instead of four. |
| 30 | |
| 31 | The LM83 is only found on a handful of motherboards. Both a confirmed |
| 32 | list and an unconfirmed list follow. If you can confirm or infirm the |
| 33 | fact that any of these motherboards do actually have an LM83, please |
| 34 | contact us. Note that the LM90 can easily be misdetected as a LM83. |

| 36 | Confirmed motherboards: |
| 37 | SBS P014 |
| 38 | |
| 39 | Unconfirmed motherboards: |
| 40 | Gigabyte GA-8IK1100 |
| 41 | Iwill MPX2 |
| 42 | Soltek SL-75DRV5 |
| 43 | |
| 44 | The LM82 is confirmed to have been found on most AMD Geode reference |
| 45 | designs and test platforms. |
