along with toolchain enhancements. aout2bb transforms a.out files with reloc information into bootblock format files with a compressed relocation info. bbstart.s relocates the bootblock using this compressed info, before jumping to C code. txlt changes some more of the absolute references to pc-relative ones (we know we have a single code + data address space). If you ever try to change this: don't even dare to change the compiler options; they were found in weeks of trial and error as the ones producing the smallest (not necessarily fastests) code. installboot is just a script around dd, for now. Some ideas by Michael Hitch, Leo Weppelman and Jason Thorpe; bugs added by myself.
