So here goes release 0.0.3 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 0.0.3:
|
|
|
|
|
- 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.
|
|
|
|
|
- Make changes to the kernel to allow more than 32 LDT entries.
|
|
|
|
|
- Trap and handle DOS and DPMI calls.
|
|
|
|
|
- Windows emulation library (connect to Peter MacDonald's library).
|
|
|
|
|
- Allowing loading of 16-bit DLLs for use with program.
|

|
|
|
- global memory allocation.
|
|
|
|
|
- complete and improve local heap allocation.
|
|
|
|
|
- Handle self-loading applications.
|
|
|
|
|
- Deal with callback functions.
|
|
|
|
|
- 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. If you installed the "ldt.tar" from the first release
|
|
|
|
|
of this package, then you MUST to replace it. 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.
|
|
|
|
|
|
|
|
|
|
BUILD:
