geometry does not match label

[Saifi Khan]

Hi all:

when i try to boot the system using FreeBSD 8.0 i386 200905
bootonly CD, the following line is shown.

GEOM: ad4: geometry does not match label (255h,63S != 16h, 63s)

i just selected the entire disk and marked it bootable in the
fdisk partition editor option.

The system has a 160GB SATA HDD with
255 heads, 63 sectors/track, 19457 cylinders

Any pointers or suggestions ?


thanks
Saifi.
