  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.
