Line 6:
=== Accessing Floppies in Real Mode ===
For bootloaders or OSes that run with the CPU remaining in [[Real Mode]], use [[BIOS
INT13h AH=2 (read) or AH=3 (write) to access floppy drives. You need to know the "drive number" (typically 0 or 1), and put that value in DL.
More detailed info can be found in the [[ATA in x86 RealMode (BIOS)]] article, because accessing a floppy is identical to accessing a hard disk
