Copyright Robert J. Amstadt, 1993. All code is provided without warranty. It is my intent to cover this code with the Gnu Public License. So here goes release 0.2.0 of the Windows loader. It will do some relocations and then run the program. I have successfully loaded the Windows solitaire game. Try it. It currently stops a call to GetObject(). WHAT'S NEW with version 0.2.0: - Alexandre Julliard has provided a replacement for the Tcl code. The new code uses Xlib and Xt directly with no intervening interpretted language. This should reduce the learning curve for casual hackers. - I changed all GLOBAL_ names to Global. WHAT'S NEW with version 0.1.1: - I have completed global memory allocation, but I don't like it. It is not 100% compatible with Windows. I need some more kernel modifications for 100% compatibility. - Alexandre Julliard has provided written better emulation for the Windows message queue. WHAT'S NEW with version 0.1.0: - Latest patches from Alexandre Julliard. - minor bug fix in if1632.S WHAT'S NEW with version 0.0.5: - Patches from Alexandre Julliard. Some integration with Tcl. - Generic interface for callback procedures. This will allow callbacks into DLLs. - MakeProcInstance() has been implemented but untested. WHAT'S NEW with version 0.0.4: - Eric Youngdale modified wine.c and selector.c to allow loading of Windows DLLs. - Added global memory allocation routines (GlobalAlloc, GlobalFree, and GlobalLock) - Bitmap resource loading into global memory. WHAT'S NEW with version 0.0.3: - Fixed bug with sector sizes. - Registers at program startup are now set correctly. - Segment fixups for relocatable-segment internal entry points. - Fixed bug in DOS PSP structure. - Some resource loading is done. - Added "return" ordinal type to build program. - Added comment capability to build program. WHAT'S NEW with version 0.0.2: - Again thanks to Eric Youngdale for some very useful comments. - The Windows startup code created by Micrsoft C 7.0 now runs to completion. - Added a new patch to the kernel to increase the usable size of the ldt to the full 32 entries currently allowed. - Imported name relocations are now supported. - Source code for my infamous test program is now included. - A handful of basic Windows functions are now emulated. See "kernel.spec" for examples of how to use the build program. WHAT'S NEW with version 0.0.1: - Eric Youngdale contributed countless improvements in memory efficiency, bug fixes, and relocation. - The build program has been completed. It now lets you specify how the main DLL entry point should interface to your emulation library routines. A brief description of how to build these specifications is included in the file "build-spec.txt". - The code to dispatch builtin DLL calls is complete, but untested. TODO: - Segment fixup code completion. - Trap and handle DOS and DPMI calls. - GlobalAlloc of code segments. - Rewrite global memory support including kernel mods to allow application to mess with page map. - complete and improve local heap allocation. - Handle self-loading applications. - Resource loading INSTALLATION: Uncompress and untar this archive into the directory of your choice. The file "ldt.tar" contains a necessary kernel patch against Linux 0.99.10. "ldt.tar" is unchanged from the version released with release 0.0.2. In the directory /usr/src/linux (or whereever you keep your kernel sources), untar this file it contains three files: kernel/ldt.c - This is source for a new system call. include/linux/ldt.h - This contains structures defining the system call interface. ldt.patch - This is a patch that must be applied to the kernel. It updates two header files, and the kernel Makefile. Or follow the same procedure with "ldt512.tar". This file contains Eric Youngdales patches for ALPHA-pl11. These patches give the emulator 512 ldt entries instead of the 32 available with the older patch kit. BUILD: The documentation for the build program is in the file build-spec.txt FINALE: Good luck, If you successfully add anything, please send me a copy. Bob Amstadt bob@amscons.com
