Chapter 4: Configuring Your Pro Tools System 57
Enabling DMA
Enabling your computer's DMA (Direct Memory 
Access) frees up CPU bandwidth so your com-
puter can do other Pro Tools tasks.
In most cases the DMA option will already be set 
correctly, as Windows detects and activates 
DMA mode by default.
To enable DMA for any IDE hard drives:
1 Right-click My Computer (Windows XP) or 
Computer (Windows Vista).
2 In the left-hand pane of the Computer Man-
agement window under System Tools, click on 
Device Manager.
3 In the right-hand pane, click the plus (+) sign 
to expand IDE ATA/API Controllers.
4 Right-click on the Primary IDE Controller and se-
lect Properties.
5 Click the Advanced Settings tab.
6 For each device, do one of the following de-
pending on your operating system:
• Set the Transfer Mode to DMA if available 
(WIndows XP)
– or –
• Check the box Enable DMA (Windows 
Vista)
7 Click OK.
8 Repeat the above steps for any additional IDE 
Channels.
9 Close the Computer Management window.
Disabling User Account Control
(Windows Vista Only)
For optimal performance with Pro Tools on 
Windows Vista, disable User Account Control 
(UAC).
To disable User Account Control (UAC):
1 Choose Start > Control Panel.
2 Double-click User Accounts.
3 Click “Turn User Account Control on or off.”

help protect your computer” option.

Disabling System Standby and Power

passes from stopping due to system resources 
powering down.

(Windows Vista):
1 Choose Start > Control Panel.
2 Double-click Power Options.
3 In the Power Options window, select High Per-

and press Backspace on your computer key-
board.

Never and the Power Options dialog closes.

changes and close the window.
