9 | Module Parameters |
| 10 | ----------------- | |
| 11 | ||
| 62aaa288 | 12 | * base: up to 4 ints |
| a417bbd3 | 13 | Base addresses for the ACCESS.bus controllers on SCx200 and SC1100 devices |
| 1da177e4 | 14 | |
| 62aaa288 JD |
15 | By default the driver uses two base addresses 0x820 and 0x840. |
| 16 | If you want only one base address, specify the second as 0 so as to | |
| 17 | override this default. | |

| 25 | Device-specific notes | |
| 26 | --------------------- | |
| 27 | ||
| 28 | The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820. | |
| 29 | If the scx200_acb driver is built into the kernel, add the following | |
| ccf988b6 MCC |
30 | parameter to your boot command line:: |
| 31 | ||
| 62aaa288 | 32 | scx200_acb.base=0x810,0x820 |
| ccf988b6 | 33 | |
| 62aaa288 | 34 | If the scx200_acb driver is built as a module, add the following line to |
| ccf988b6 MCC |
35 | a configuration file in /etc/modprobe.d/ instead:: |
| 36 | ||
| 62aaa288 | 37 | options scx200_acb base=0x810,0x820 |
