There are two parameters, sectors_per_head and heads_per_cylinder which are not
stored in the MBR. So at ISO production time it is more or less arbitray how

to convert a LBA into a C/H/S address and vice versa.
At boot time the x86 BIOS decides about the two parameters. The boot loader may
inquire these values by INT 0x13 AH 0x08 and use them to convert LBA to C/H/S
