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