-=== Linking ===
+=== Compiling and Linking the modules ===
-Link the whole thing with:
+Assemble stub.asm with:
+ nasm -f elf stub.asm -o stub.o
+The Pascal modules with:
+ fpc -Aelf -n -O3 -Op3 -Si -Sc -Sg -Xd -Rintel -Tlinux kernel.pas
+* -Aelf - instructs the internal fpc assembler to output an ELF object.;
+* -n - ignores fpc.cfg;
+* -O3 - perform level 3 optimizations;
+* -Op3 - tune code for PentiumPro / P-II / Cyrix 6x86 / K6 (TM);
+* -Si - enable C++ style INLINE keyword;
+* -Sc - enable C style operators;
+* -Sg - enable support for labels;
+* -Xd - tells the compiler to forget the standard library path;
+* -Rintel - sets the inline assembly syntax to intel style;
+* -Tlinux - specifies that the target operating system is Linux. (Don't even ask!)
+ ppc32 -a -Aas -n -O3 -Op3 -Si -Sc -Sg -Xd -Tlinux -Rintel kernel.pas
+Then link the whole thing with:
  ld -Tlinker.script -o kernel.obj stub.o kernel.o multiboot.o system.o console.o
