Once again AHCI programming, but this time a demonstration on how to do a fast read from a drive in AHCI mode.

First SATA drives are detected. Then a fast DMA read command is executed repeatedly on the first detected drive from sector 0 till the end. The source code compiles under a recent version of WATCOM C++ (1.9 or higher).
