xPC Target

Restrictions

The following restrictions apply to the booted DOS environment when you use xpcboot.com to execute the target applications:

• The CPU must be executed in real mode
• While loaded in memory, the DOS partition must not overlap the address range of a target application

You can satisfy these restrictions by avoiding the use of additional memory managers like emm386 or qemm. Also, you should avoid any utilities that attempt to load in high memory space (for example, himem.sys). If the target PC DOS environment does not use a config.sys file or memory manager entries in the autoexec.bat file, there should not be any problems when running xpcboot.com.

It is also necessary that your TargetMouse setting is consistent with your hardware. Some PC hardware may use an RS232 port for the mouse, while others use a PS2 mouse. If a mouse is not required in your application, you may choose to select None as your setting for the TargetMouse.
