README.TXT Release: RSX 5 (c) Rainer Schnitker Dec 1994

This is RSX, the DPMI-extender for EMX and DJGPP programs.
RSX can run the GCC programs under DPMI-servers like MS-Windows 3.1
and simulates a missing 387/487.
News in release 5:
- 32 bit RSX extender default now
- pipes, software scheduler; 'gcc -pipe' works
- rsx can run Emacs 19.27 (emx)
- new emx syscalls (select, bsd signals, pipe)
- tested with OS/2 Warp; _memaccess() workaround
- int10 vesa support
- bugs fixed
UNZIP RSX-ARCHIVE:
First you should delete older RSX versions.
Unpack this archive with unzip50 or pkunzip2
C:\> UNZIP A:\DPMIGCC5.ZIP

Please read INSTALL.TXT in this archive before using this software.
WHY USING RSX FOR EMX PROGRAMS:
-------------------------------
RSX can run unmodified EMX 0.8-0.9a programs under DPMI 0.9/1.0.
The compiler and other EMX programs can run in a MS-Windows or OS/2 DOS-box.
Also RSX supports system calls that are not available under EMX+DOS.
WHY USING RSX FOR DJGPP PROGRAMS:
---------------------------------
RSX can run the DJGPP 1.08-1.11 compiler under DPMI 0.9/1.0.
You don't need a coprocessor, a FPU-emulator will do this job.
RSX support also ptrace(), signal(), wait(), fork(), spawnve(P_DEBUG).
If you use the DJGPP compiler only under DPMI, gcc + rsx is faster than
gcc + go32.
