I had a go too, I think I've cracked it, but my wife got rather attached to the X11 display, so I couldn't test it at the time... One thing I think Gary had done, was move the kzip data to 0x100000, and uncompressed the kernel at the end of the kzip image. So far as I can tell, this left a 900KB "hole" in extended memory below the uncompressed kernel, as the memory probe routine didn't check for extended memory below the kernel. I did it by improving the overlapping uncompress. I actually have a copy of Jordan's "MFSKERNEL", and am about to give it another test run. Cheers, -Peter
