Special thanks to Wayne Yen, Jin-Lon Hon, and Alex Win of BusLogic, whose

advice has been invaluable, to David Gentzel, for writing the original Linux
|

BusLogic driver, and to Paul Gortmaker, for being such a dedicated test site.

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

CCBs only in having the TagEnable and QueueTag fields moved from byte 17 to

Extended LUN Format CCBs can support up to 64 Logical Units, but in practice

the SCSI-2 specification defines Bit 5 as LUNTAR. Extended LUN Format CCBs

are used by recent versions of the MultiMaster Firmware, as well as by the

FlashPoint SCCB Manager; the FlashPoint SCCB Manager only supports 32 Logical

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

since they are problematic for the above reasons, and since limiting them to

5 bits simplifies the CCB structure definition, this driver only supports

32 Logical Units per Target Device.
