Chapter 8 Ultra ATA Storage Driver
Setup
8.1 Introduction
This driver takes advantage of the latest Intel ® Ultra ATA controller features 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, without 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.
