Chapter 8 Ultra ATA Storage Driver

8.1 Introduction

This driver takes advantage of the latest Intel ® Ultra ATA controller fea-
tures to improve both storage subsystem performance and overall system
performance. A useful diagnostic tool, Intel Ultra ATA Companion® ,
shows technical information of the ATA subsystem.

8.2 Features

• The driver enables fast Ultra ATA transfers by default.
• Users no longer have to manually enable DMA transfers for each ATA
and/or ATAPI peripheral devices.
• Each ATA channel has independent device timings/transfers which
allows PIO-only and DMA-capable devices to share the same ATA
controller cable, where one is the master and the other the slave, with-
out restricting transfer mode to PIO-only for both devices.
• Technical details of the ATA subsystem can be viewed via use of the
application.
• Drivers are optimized.
