| 23 | Changes: |
| 24 | 24.08.2002 |
| 25 | Fixed the typo in sis630_access (Thanks to Mark M. Hoffman) |
| 26 | Changed sis630_transaction.(Thanks to Mark M. Hoffman) |
| 27 | 18.09.2002 |
| 28 | Added SIS730 as supported. |
| 29 | 21.09.2002 |
| 30 | Added high_clock module option.If this option is set |
| 31 | used Host Master Clock 56KHz (default 14KHz).For now we save old Host |
| 32 | Master Clock and after transaction completed restore (otherwise |
| 33 | it's confuse BIOS and hung Machine). |
| 34 | 24.09.2002 |
| 35 | Fixed typo in sis630_access |
| 36 | Fixed logical error by restoring of Host Master Clock |
| 37 | 31.07.2003 |
| 38 | Added block data read/write support. |
