I don't know about Linux, but Windows certainly has different modules to ha= ndle the different processors. You can have problems if somehow an AMD modu= le gets applied to an Intel processor installation. It is all hidden from the installer and user by the HAL module. But when it comes to end user applications, it is anyones guess as to the = code having switchable linked modules for the processor type. I guess if th= ey are wanting to squeeze the very last ounce of performance out of somethi= ng then they may do it, but I suspect for most applications they use the 'c= ommon instruction set' in the compiler. --=20 Scanned by iCritical. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
