   -----------------------------------------------------------------
              Option: global_tag_depth
          Definition: Global tag depth for all targets on all busses.

                      may be selectively overridden vi the tag_info
                      option.
     Possible Values: 1 - 253

          Definition: Set the per-target tagged queue depth on a
                      per controller basis.  Both controllers and targets
                      may be ommitted indicating that they should retain
                      the default tag depth.
            Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
                        On Controller 0

          Definition: Enable read streaming on a per target basis.
                      The rd_strm_bitmask is a 16 bit hex value in which
                      each bit represents a target.  Setting the target's
                      bit to '1' enables read streaming for that
                      target.  Controllers may be ommitted indicating that
                      they should retain the default read streaming setting.

                        On Controller 0
                          enables read streaming for targets 0 and 6.
                          disables read streaming for targets 1-5,7-15.
                        All other targets retain the default read
                        streaming setting.
             Example: rd_strm:{0x0023,,0xFFFF}
                        On Controller 0
                          enables read streaming for targets 1,2, and 5.
                          disables read streaming for targets 3,4,6-15.
                        On Controller 2
                          enables read streaming for all targets.
                        All other targets retain the default read
                        streaming setting.
                      
     Possible Values: 0x0000 - 0xffff

          Definition: Set Domain Validation Policy on a per-controller basis.
                      Controllers may be ommitted indicating that
                      they should retain the default read streaming setting.
             Example: dv:{-1,0,,1,1,0}
                        On Controller 0 leave DV at its default setting.
                        On Controller 1 disable DV.
                        Skip configuration on Controller 2.
                        On Controllers 3 and 4 enable DV.
                        On Controller 5 disable DV.

     Possible Values: < 0 Use setting from serial EEPROM.
                      0 Disable DV
                      > 0 Enable DV
       Default Value: DV Serial EEPROM configuration setting.

                      basis.
                      Controllers may be ommitted indicating that
                      they should retain the default precompensation setting.
             Example: precomp:{0x1}
                        On Controller 0 set precompensation to 1.
             Example: precomp:{1,,7}
                        On Controller 0 set precompensation to 1.

4. Additional Notes

   4.1. Known/Unresolved or FYI Issues

        * Under SuSE Linux Enterprise 7, the driver may fail to operate
          correctly due to a problem with PCI interrupt routing in the
          Linux kernel.  Please contact SuSE for an updated Linux
          kernel.

   4.2. Third-Party Compatibility Issues

        * Adaptec only supports Ultra320 hard drives running
          the latest firmware available. Please check with
          your hard drive manufacturer to ensure you have the
          latest version.

   4.3. Operating System or Technology Limitations
        
        * PCI Hot Plug is untested and may cause the operating system 
          to stop responding.
        * Luns that are not numbered contiguously starting with 0 might not
          be automatically probed during system startup.  This is a limitation
          of the OS.  Please contact your Linux vendor for instructions on
          manually probing non-contiguous luns.
        * Using the Driver Update Disk version of this package during OS
          installation under RedHat might result in two versions of this
          driver being installed into the system module directory.  This
          might cause problems with the /sbin/mkinitrd program and/or
          other RPM packages that try to install system modules.  The best
          way to correct this once the system is running is to install
          the latest RPM package version of this driver, available from
          http://www.adaptec.com.
