Component Overview: Intel® Application Accelerator Driver
®
The Intel
Application Accelerator Driver component is a Windows* Hardware Quality Labs <http://
www.microsoft.com/hwtest/default.asp> (WHQL) certified component designed specifically with the in-
tention to increase the disk to system subsystem speed.
®
The Intel
Application Accelerator has the ability to query the storage component via an IOCTL interface
and to obtain detailed Ultra ATA Controller and device information, which is displayed in the Device Infor-
mation Property Page, which can be saved to a file and displayed in the Report Property Page.
In addition, a refresh function can be used to refresh the Device Information Property Page when devices are
swapped under mobile configurations. The refresh function can be activated by pressing the "F5" function
key, located on the keyboard, or by clicking on the menu found at "View" then "Refresh F5".
Component Overview: Displaying Controller and Device Information
When opened, the Devices window in the Device Information property page contains entries for the Intel
Ultra ATA controller and all connected ATA/ATAPI. Selecting a particular controller or device in the De-
vices window causes the application to display the corresponding configuration parameters in the Device
Information window. Parameters shown with an oscilloscope icon are read-only; parameters shown with a
wrench icon are read-write. The various parameters are described below on the next screen:
