I do have an older dump which does report errors when I tried to install on a partition which was to small (included below). I suspect some error may be tracked from that info. My skimming of that site seems to indicate that calculations of C/H/S are not as standard as one would hope, and the safe way might be to use the bios call (a thought from the hip based on a 5 minute skim).
