SUMMARY
If you are using the Stacker XT/8 Coprocessor with Microsoft Windows running in 386 enhanced mode, you need to add an EMMExclude statement to the [386Enh] section of the SYSTEM.INI file.

NOTE: This does not apply to the Stacker AT/16 Coprocessor because it does not use a RAM address.

MORE INFORMATION
The range of memory addresses depends on the base address of the Stacker XT/8 card. The base address is found on the Stacker DEVICE statement in the CONFIG.SYS file and is identified by the /B parameter.

The following table lists the seven possible memory ranges, based on the base address of the XT/8 Coprocessor card:

  Base Address     to Exclude --

c400            c400-c7ff c800            c800-cbff cc00            cc00-cfff d000            d000-d3ff d400            d400-d7ff d800            d800-dbff dc00            dc00-dfff For example, if the Stacker XT/8 Coprocessor base address is d000, using Notepad, add the parameter listed below to the SYSTEM.INI file under the heading [386Enh]:

  EMMEXCLUDE=d000-d3ff The Stacker products included here are manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
