| 17 | Unless you like data loss puzzles, always be sure that any chip |
| 18 | you configure as a 24c32 (32 kbit) or larger is NOT really a |
| 19 | 24c16 (16 kbit) or smaller, and vice versa. Marking the chip |
| 20 | as read-only won't help recover from this. Also, if your chip |
| 21 | has any software write-protect mechanism you may want to review the |
| 22 | code to make sure this driver won't turn it on by accident. |
| 23 | |
| 24 | If you use this with an SMBus adapter instead of an I2C adapter, |
| 25 | full functionality is not available. Only smaller devices are |
| 26 | supported (24c16 and below, max 4 kByte). |
| 27 | |
| 28 | This driver can also be built as a module. If so, the module |
| 29 | will be called at24. |
