8 | parport handling is not an option. The drawback is a reduced portability |
9 | and the impossibility to daisy-chain other parallel port devices. | |

13 | Module parameters: | |
14 | ||
15 | * type: type of adapter (see i2c-parport or modinfo) | |
16 | ||
17 | * base: base I/O address | |
18 | Default is 0x378 which is fairly common for parallel ports, at least on PC. | |
19 | ||
20 | * irq: optional IRQ | |
21 | This must be passed if you want SMBus alert support, assuming your adapter | |
22 | actually supports this. |
