| 4 | |
| 5 | This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint |
| 6 | Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for |
| 7 | Linux compatibility. It was provided by BusLogic in the form of 16 separate |
| 8 | source files, which would have unnecessarily cluttered the scsi directory, so |
| 9 | the individual files have been combined into this single file. |

| 4932 | * checks bus master command complete and dual rank busy |
