This indicates that the Pinnacle can not obtain a free contiguous 32K Upper
Memory block.

Try the following suggestions to resolve the problem:

1) Choose another memory address until you no longer get the error.

2) Make sure you have no memory managers such as EMM386.EXE running in the
   CONFIG.SYS file. To check on this, open Sysedit 
   (Start | Run | type in "sysedit" and click OK).   
   If this line is in your CONFIG.SYS, you should put the letters REM
   and a space in front of the line, which will make Windows ignore it.
   The line should now look like this:

        REM C:\WINDOWS\EMM386.EXE (plus additional "switches")

3) Make sure that there are no memory exclusions in your SYSTEM.INI file
   (in the Windows folder).  To check on this, open Sysedit
   (Start | Run | type in "sysedit" and click OK).  
   In the  [386enh] section of the SYSTEM.INI file you may see:

        EMMExclude=D000-D7FF

   If it is there, put a semi-colon (" ; ") at the beginning of the line 
   to disable it. 
   The line should now look like this:

        ;EMMExclude=D000-D7FF

4) Disable all shadowing in the BIOS (examples: Video Shadow, Bios Shadow).
   The motherboard BIOS may be reserving UMB (Upper Memory Blocks) for
   SHADOW RAM and Windows may not report them as being in use.

5) If the BIOS has an ICU (ISA Configuration Utility) or PnP Configuration 
   area, check for an option "Memory Base Address" or  "ISA Used Memory".  
   Use this to reserve a 32kB Upper Memory Block for the Pinnacle at the 
   memory address the Pinnacle driver is set to in Windows 
   (e.g. D800, D000, C800).  
   For step-by-step instructions, see
   "Install Tricks" in the "Power Tips" section of the Knowledge Base FAQ's.

6) Reduce the AGP aperture setting in your BIOS to the lowest possible value, 
   even if you do not have an AGP card installed in the AGP slot.  
   Higher aperture settings tend to use more upper memory blocks.

7) Some SCSI controller cards or cable modems require more upper memory blocks
   than Windows reports.  Typically, Windows does not report small increments
   of upper memory being used, and these small "slivers" of memory will not be
   "seen" by the Device Manager.  As a result of this, a specific memory range
   that appears to be available actually is not.  To overcome this problem, 
   leave one 32kB block unused for the "slivers" to fall in.

   For example:
      If the SCSI card occupies C800-CFFF, then set the Pinnacle to D800-DFFF.
      This way, the 32 K block used by the Pinnacle is unaffected by the
      memory "slivers" left over in the D000-D7FF memory range.

8) Video cards using drivers supplied by the manufacturer (even by Windows)
   may use more upper memory blocks than "Standard VGA" drivers.
      a) Remove these drivers and use the "Standard VGA" drivers instead.
      b) Install the Pinnacle.
      c) Re-install the original drivers for the video card.

9) Disable USB in the BIOS.  USB requires a 4kB sliver of upper memory that
   can sometimes overlap or conflict with the Pinnacle memory range.

Note: Motherboards also use memory for system resources (PnP extensions,
      USB Support, Power Management, etc.)  Check with the motherboard
      manufacturer for specific resource issues associated with your
      motherboard.
