Is this right? ] End addressses must be rounded to a cylinder boundary so that the ending h/s values are maximal so that FreeBSD can determine the geometry by looking at the ending h/s values. I don't know of any requirements for rounding start addresses, except that some MBR extensions abuse the usual DOS rounding by taking more than 1 sector. Bruce
