Im having to create a new builder for it, because it's a.out format and only compiles with amsterdam compiler kit. porting to gcc would be quite a big job. the kernel image itself is also a strange format, not just a.out, but multiple a.out processes concatenated together. For these reasons i decided a new builder was needed. could I get the builder to map all the available memory into the bootstrap pagetables? Regards Ivan Kelly
