| | Logical Block Addressing (LBA) Defined |
 | | Prior to this technology, ROM BIOS limitations prevented the fdisk command from using an entire hard disk that was larger than 504 megabytes (MB) in size, except by using other controller ROM routines that effectively translate the hard disk's native geometry. |
 | | LBA is a run-time function of the system BIOS. |
 | | The BIOS uses LBA for the following commands: read (with and without retries), read verify, read long, write (with and without retries), write verify, write long, read multiple, write multiple, read DMA, write DMA, seek, and format track. |
