Heads are limited to 63, sectors are limited to 255.  255 * 63 * 1024
equals about 8GB.  If you have a hard drive larger than 8GB, you can't
use remapping to make it show up as 1024 cyls or less.  If you need to
boot from it, create a 50MB /boot.  Once the kernel is up, it can handle
a single large partition.
