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.
22
23 Finally, special thanks to Mylex/BusLogic for making the FlashPoint SCCB
24 Manager available as freely redistributable source code.

835 CCBs only in having the TagEnable and QueueTag fields moved from byte 17 to
836 byte 1, and the Logical Unit field in byte 17 expanded to 6 bits. In theory,
837 Extended LUN Format CCBs can support up to 64 Logical Units, but in practice
838 many devices will respond improperly to Logical Units between 32 and 63, and

840 are used by recent versions of the MultiMaster Firmware, as well as by the
841 FlashPoint SCCB Manager; the FlashPoint SCCB Manager only supports 32 Logical
842 Units. Since 64 Logical Units are unlikely to be needed in practice, and
843 since they are problematic for the above reasons, and since limiting them to
844 5 bits simplifies the CCB structure definition, this driver only supports
845 32 Logical Units per Target Device.
