| Jean Delvare | 62aaa28 | 2006-06-12 21:48:08 +0200 | [diff] [blame^] | 13 | By default the driver uses two base addresses 0x820 and 0x840. |
| 14 | If you want only one base address, specify the second as 0 so as to |
| 15 | override this default. |

| 23 | Device-specific notes |
| 24 | --------------------- |
| 25 | |
| 26 | The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820. |
| 27 | If the scx200_acb driver is built into the kernel, add the following |
| 28 | parameter to your boot command line: |
| 29 | scx200_acb.base=0x810,0x820 |
| 30 | If the scx200_acb driver is built as a module, add the following line to |
| 31 | the file /etc/modprobe.conf instead: |
| 32 | options scx200_acb base=0x810,0x820 |
