WebThe IDE controller uses a single 16-bit I/O port as a FIFO for reading and writing sector data. The first example calls the PCI I/O Protocol 256 times to write the sector. The second example calls the PCI I/O Protocol once to perform the same operation, providing better performance if compiled with an EBC compiler.
