notice youo have 16 heads as shown in 16383/16/63

notice you have 255 heads for fdisk...

cylinders will never match since the real chs is being mapped by
LBA so the bios can get to the corresponding chs from the i/o system calls
- you will run out of bits in the lba translation table
which limits you to 32GB or 132GB and higer or lower disk
capacity limits depending on the bios using the "fixed" number
of lba bits
( never did understand why they picked 12-bit lba and not go
straight to 16-bit or 32-bit lba )
