"and about your riffered sit http://developer.intel.com there i dont even get a reply nor the required data"

Had a quick look around:
What about the Pentium 4 Processor Forum:

Or the IA-32 Processors page - which seems to cover all Pentium variants:

You can download the lastest Borland C++ Compiler from
http://www.borland.com/products/...ilder.html
Note that this is the compiler only - no GUI, and definitely not the full C++ Builder RAD suite!!
This is a native x86 Compiler, though I'm not sure if this version gives you completely PC-independent code?

If you search around, I think you can still get the earlier version (about 3?) which definitely could produce PC-independent code suitable for embedded use.

It's a long time since I did anything embedded with an x86 (8086, 8088, and 80186) - I have never done anything embedded with a 286 or higher, so I certainly can't help you with a Pentium! :-(
