One method, which I think may be mentioned in the Handbook, is to
boot the Windows install CD (that presumably came with the Presario)
and use its fdisk to create a small partition.  You don't need to
actually install Windows, just create a partition as if you were
going to install it.  Then boot the FreeBSD CD and sysinstall will
figure out the geometry from the Windows master boot record.
