| Matt LaPlante | 5d3f083 | 2006-11-30 05:21:10 +0100 | [diff] [blame] | 4 | This works better than on other platforms, because the FSB of the CPU |
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 5 | can be controlled independently from the PCI/AGP clock. |

| 7 | The module has two options: |
| 8 | |
| 9 | fid: multiplier * 10 (for example 8.5 = 85) |
| 10 | min_fsb: minimum FSB |
| 11 | |
| 12 | If not set, fid is calculated from the current CPU speed and the FSB. |
| 13 | min_fsb defaults to FSB at boot time - 50 MHz. |
| 14 | |
| 15 | IMPORTANT: The available range is limited downwards! |
| 16 | Also the minimum available FSB can differ, for systems |
| 17 | booting with 200 MHz, 150 should always work. |
