Before starting, it is important to know your hard disk's geometry (i.e., number of cylinders, heads and sectors/track). If installing FreeBSD on the same disk as another operating system, then the two systems should use the same geometry. In particular, FreeBSD's default geometry is inappropriate for MS-DOS. So in this case, the DOS geometry should be used instead. [This seems to be true for SCSI disks. What about IDE? With the new boot blocks, can we ignore the disks true geometry??]
