4 Embedded Option
4-8
Restrictions
The following restrictions apply to the booted DOS environment when you use
xpcboot.com to execute the target applications:
• The CPU must execute in real-time mode.
• While loaded in memory, the DOS partition must not overlap the address
range of a target application.
To satisfy these restrictions,
• Do not use additional memory managers like
emm386 or qemm.
• Avoid any utilities that attempt to load in high memory (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 be no
problems when running
xpcboot.com.
• Ensure that the
xpcexplr TargetMouse option setting is consistent with
your hardware. Some PC hardware might use an RS-232 port for the mouse,
while others use a PS2 mouse. If a mouse is not required in your application,
select
None as your setting for the TargetMouse. Choosing this setting helps
prevent problems.
