A Complete Example

Assume you have two PCs: a host running Windows and a target. We want to run a test program compiled with Borland C++.

Let's create the following test program in file Hello.c:

#include <stdio.h> 

int main(void) 
{ 
   printf("Hello, RTTarget-32!\n"); 
   return 0; 
}

Now we can compile and link the program like this ¹:

bcc32 Hello.c Rtt32.lib

To be able to run the program on the target, we must locate the program. For this purpose, a small configuration file must be created (Hello.cfg):

Region  NullPage    0     4k  RAM 
Region  LowMem      4k  636k  RAM 
Region  HighMem     1M    1M  RAM 
 
Locate  BootCode    Biosboot.exe  LowMem 
Locate  BootData    SystemData    LowMem 
Locate  DiskBuffer  DiskBuffer    LowMem 
Locate  Header      Hello         LowMem 
 
Locate  NTSection   CODE          HighMem 
Locate  NTSection   DATA          HighMem 
Locate  Stack       Stack         HighMem 16k 
Locate  Heap        Heap          HighMem

Now we can locate using command²:

RTLoc Hello

which will produce files Hello.rtb (the relocated program image) and Hello.loc (a detailed map file).

Now a bootable disk with our program is created. Insert an empty, formatted disk in drive A: and type:

BootDisk Hello A:

Place the disk in the drive of the target computer and reboot it. RTTarget-32's boot code will then initialize the PC, read your program from the diskette, switch to 32-bit protected mode, and execute the program.
