11.10 Address Offset Feature (vendor specific) Computer systems perform initial code loading (booting) by reading from a predefined address on a disk drive. To allow an alternate bootable operating system to exist in a reserved area on a disk drive this feature provides a Set Features function to temporarily offset the drive address space. The offset address space wraps around so that the entire disk drive address space remains addressable in offset mode. The Set Max pointer is set to the end of the reserved area to protect the data in the user area when operating in offset mode. This protection can be removed by a Set Max Address command to move the Set Max pointer to the end of the drive. But any commands which access sectors across the original native maximum LBA are rejected with error, even if this protection is removed by a Set Max Address command.
