The author respectfully requests that any modifications to this software be

sent directly to him for evaluation and testing.

|

|
|
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
|

|
|
byte 1, and the Logical Unit field in byte 17 expanded to 6 bits. In theory,
|
||
|
|
Extended LUN Format CCBs can support up to 64 Logical Units, but in practice
|
||
|
|
many devices will respond improperly to Logical Units between 32 and 63, and
|
||
|
|
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.
