----------------------------------------
  Bug fix:
  ------------
  1. Problem: 
       xD H type cards are not detected when the base clock is at 200MHz. 
     Cause:
       xD H type card access timing values are different than the non-H
       type cards when base clock is at 200MHz.
     Change:
       Use H type access timing values for H type cards.

Version 1.1.8.0 - September 30, 2011
----------------------------------------

  ========
  1. Problem: 
        When inserting or removing xD media, system may BSOD,
        DPC timeout.
     Cause:
        A bug is introduced in the previous version of the driver
        where the interrupt state may not be updated correctly when
        a media is inserted or removed. Under certain timing conditions,
        it may confused the driver to complete a bogus transaction which
        may lead to system crash or hang.

        Sector read/write may timeout when disabling MS/SD
        functions.
     Cause:
        Windows may mask off interrupt for more than 2 seconds
        when disabling a MS/SD function which exceeds the timeout
        limit set by the xD driver.
     Fix:
        Increase the timeout limit.
  
  2. Problem:
        16MB and 32MB cards are not detected.
     Cause:
        The number of address cycle is not programmed correctly.
     Fix:
        Program the correct value for the affected cards.

  
   3. Problem:
        Some cards are not detected.
     Cause:
        Second read following a read on 32th page will not complete.

  ========
  1. Problem: 
        CQ#47941 CR-XD:Unplugging an XD card will cause a 
           blue screen during a file transfer
     Fix:
        Added code to support ungraceful removal during file IO.

Version 1.0.0.8 - Jun 08, 2010
----------------------------------------

  Bug Fix:
  ========
  1. Problem: 
        CQ#48063 CR_SD3.0_xD: BSOD occurs while formatting SD card 
        if xD driver is installed.
     Cause:
        The xD card reset event could interfere with the SD card's 
        operation.
     Fix:
        Changed the xD card detection logic such that it doesn't 
        affect the SD bus.


Version 1.0.0.7 - Jun 03, 2010
----------------------------------------

  Bug Fix:
  ========
  1. Problem: 
        Resuming from S3/S4 from VDISK mode may BSOD.
     Fix:
        Do not touch interrupt in VDKSK mode.

  2. Problem: 
        A bug was introduced in previous version that the xD card
        CIS string is not properly copied.

  3. Problem:
        Resume from S3/S4 on Win7 system would BSOD.
     Casue:
        The forced bus rescan causes side effect on some systems that
        doesn't need the workaround. SCSIPORT would stuck the PNP
        state transition which causes BCC_9f subcode 4.
     Fix:
        Removed the power management workaround implemented in v1.0.0.3.

  4. Problem:
       CQ48146 Aspen-CR-XD: Unable to Access XD device after resume from S3/S4.
     Cause:
       This is newly introduced while fixing other bugs. The driver would 
       mistakenly enable ECC and/or disable DMA access. It will make the access
       to the media very slow and/or not able to access the media due to outstanding
       ECC problem.
    Fix:
       Correct the driver so that it doesn't alter the setting incorrectly.

  Known issues:
  =============
  1.  Symptom:
        The media may not be detected if inserted after resuming from S3/S4 on
        some systems.
      Cause:
        A workaround for SCSIport power management is removed to address problem #3
        in the bug fix list.
      Workaround:
        The media should be detected again if user go to device manager and perform
        a "scan for new hardware".
      Future action:
        This problem will be fix in next release.


Version 1.0.0.5 - May 26, 2010
----------------------------------------

  Bug Fix:
  ========
  1. Problem: 
        CQ47933 CR-XD: The XD device will disappear after resuming 
        from s3/s4 during a file transfer.
     Fix:
        Finished power management code.

  2. Problem: 
        CQ47934 CR-XD: The XD device will disappear from Windows 
        explorer after running  the disable/enable test.

        CQ47935 CR-XD: Unable to auto detect XD device after installing 
        the driver when the XD card is already plugged in

     Cause:
        The controller may or may not generate card insertion interrupt
        when a xD card is inserted.
     Fix:
        Change the detection logic such that the driver to poll the card state 
        at initialization and resuming from S3, S4 mode.

   Enhancements:
   =============
   1. Request: 
      Enhance the driver so that it handles the case where xD media is unpluged 
      in the middle of building FTL table.
   2. Request:
      Recover from some hardware access timeout gracefully.
       

Version 1.0.0.4 - May 19, 2010
----------------------------------------

  Bug Fix:
  =============
  1.  Request:
        System may prompt to format the media even
        the media has been formatted previously when
        DMA is turned on.
      Cause:
        The shared memory is not aligned to DMA boundary
        so that the chip may generate DMA interrupt prematurely
        causing invalid data being read.
      Change:
        Force the shared memory align to DMA boundary.
      Impact:
      Notes:

  2.  Request:
        Read Tail operation timeout if ECC mode is on.
      Change:
        Always clear enable ECC bit when reading tail.
      Impact:
      Notes:
   
   Enhancements:
   =============
   1.  Request:
         Turn DMA on by default.
       Change:
         As requested.

Version 1.0.0.3 - May 18, 2010
----------------------------------------

  Bug Fix:
  =============
  1.  Request:
        Virtual Disk may not suspend to S3 or S4.
      Change:
        Set the flags for storage device properly.
      Impact:
      Notes:

  2. Request:
       On some systems, scsi miniport may not get notification
       when resuming from S3.
     Change:
       Force a bus rescan in the bus driver.
     Impact:
     Notes:
      
Version 1.0.0.2 - May 13, 2010
----------------------------------------

  Enhancements:
  =============

        Single INF file to install both drivers.
      Change:
      Impact:
      Notes:

  2. Request:
       Initial AMD64/X64 support.
     Change:
     Impact:
     Notes:

  3. Request:
       Enabled virtual disk io to test UM functionality.
     Change:
     Impact:
     Notes:
     



Restrictions + known issues (will be fixed in later versions):
==============================================================
  1.  Does not recover from hardware access timeout.
      System will hang, BSOD when hardware access failure.
  2.  Does not support ECC.
  3.  DMA has to be disabled when building FTL mapping table. 
      On some system, FTL table may take more than 30 seconds
      build. The media will not appear until the FTL table
      is built.
  4.  No power management (sleep, resume ..)
  5.  Media may not be detected when the driver starts with 
      media inserted. To workaround this, one should insert
      the media after the driver started or unplug and plug in
      the media.
  6.  x86 only
  7. Limited SCSI command emulation.

Version 1.0.0.0 - May 01, 2010
