11 | ||
12 | Special thanks to Wayne Yen, Jin-Lon Hon, and Alex Win of BusLogic, whose | |
13 | advice has been invaluable, to David Gentzel, for writing the original Linux | |
14 | BusLogic driver, and to Paul Gortmaker, for being such a dedicated test site. | |
15 | ||
16 | Finally, special thanks to Mylex/BusLogic for making the FlashPoint SCCB | |
17 | Manager available as freely redistributable source code. | |
