19 Special thanks to Wayne Yen, Jin-Lon Hon, and Alex Win of BusLogic, whose
20 advice has been invaluable, to David Gentzel, for writing the original Linux
21 BusLogic driver, and to Paul Gortmaker, for being such a dedicated test site.

23 Finally, special thanks to Mylex/BusLogic for making the FlashPoint SCCB
24 Manager available as freely redistributable source code.

1148 Units. Since 64 Logical Units are unlikely to be needed in practice, and
