Extended LUN Format CCBs differ from Legacy LUN Format 32 Bit Mode  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.
