Nota Bene</H1 ><P >Ori's original document was good about supporting earlier versions of Linux, going all the way back to the 2.0 days. I had originally intended to keep with the program, but after thinking about it, opted out. My main reason to keep with the compatibility was for GNU/Linux distributions like LEAF, which tended to use older kernels. However, even LEAF uses 2.2 and 2.4 kernels these days.</P ><P > </P ><P >Both Ori and I use the x86 platform. For the most part, the source code and discussions should apply to other architectures, but I can't promise anything. One exception is <A HREF="interrupthandlers.html" >Chapter 12</A >, Interrupt Handlers, which should not work on any architecture except for x86.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="x34.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="c43.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Authorship And Copyright</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="f23.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Introduction</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
