Win32 x86 emulation on PowerPC V1.01 (Wx86) 10/18/96

Installation Options:

   1. Add/Remove Programs Control Panel Applet thru Install\Uninstall page.
      Use the Install button and browse for w86setup.exe.

   2. instwx86.exe - installs\uninstalls Wx86 binaries

      Usage: instwx86 [/q /u PathInf]

         PathInf specifes path to Wx86.inf\n"
         /q   Quiet Mode for unattended setup\n"
         /u   Uninstall\n"
         /?   Usage (this information)\n"

   3. Explorer File Type association for Wx86.inf.
      Right click om Wx86.inf, choose Install option.

   The machine must be rebooted for Wx86 emulation to become active.


win32 app caveats and limitaions:

   1. Some win32 x86 application setups are initiated by a Win16 executable
      that determines the machine type by looking at the environment variables
      PROCESSOR_ARCHITECTURE and PROCESSOR_IDENTIFIER. If they
      are not set as follows, they complain about an incorrect version of
      Windows and refuse to install. The work around is:

         - Open Control Panel, System, Environment
         - set PROCESSOR_ARCHITECTURE=x86
         - set PROCESSOR_IDENTIFIER=80486-1
         - From the command line execute:  kill -f ntvdm
         - run application setup

   2. We intend to support all win32 apis, which are common between Win95
      and WinNT 4.0. We do not support Ntoskrnl apis. If there are apis
      for which support has not yet been added, and they are blocking
      testing or common usage send email to Wx86 and we will add it to the
      priority list.

   3. Debug support is very limited, we only support ntsd with Wx86e.dll
      (ntsd extension dll) for debugging x86 processes. We do not support
      x86 debuggers, windbg, nor Dr.Watson.

   4. Alpha platforms currently have limitations associated with the
      difference in the page size granularity. Alpha uses 8K pages while
      all other winnt platforms use 4K pages. This can produce problems
      with applications which assume that the machine's page size is 4K
      and depends on the 4K granularity for correct operation. This also
      makes it impossible to support shared dll data sections, if the
      application uses a 4K image alignment. In this case the shared dll
      data sections are treated as normal instance data and are not shared
      between process.  Shared dll data sections are supported correctly
      if the image alignment is a multiple of 8k.
