                      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.

        enables verbose output in the driver and turns read streaming on
        for targets 0 and 6 of Controller 0.

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.
