Installing Pro Tools|HD Cards
in a Windows Computer
This section shows how to install Pro Tools|HD
cards into a PC.
Disabling Driver Signing Warnings
Before you install Pro Tools|HD cards, temporar-
ily disable the Driver Signing warning option for
Windows XP. This expedites and automates
much of the installation process. If you do not
temporarily disable this option, warning mes-
sages (that you are installing an unsigned driver)
will appear for each DSP chip detected during
software installation.
To disable the warning option on Windows:
1 Right-click on My Computer and choose Proper-
ties.
2 Click the Hardware tab in the System Proper-
ties dialog.
3 Click the Driver Signing button.
4 Select “Ignore—Install the software anyway and
don’t ask for my approval.”
5 Click OK to close the Driver Signing Options
window.
6 Click OK to close the System Properties dialog.
7 Shut down the computer.
Figure 4. PCIe card installed
Do not force the card into the PCIe card sup-
port slot. When you have the correct instal-
lation angle, the card should slide in easily.
If you do not have the correct angle, reposi-
tion the card.
The card’s PCIe connectors will not seat
completely until you have replaced the
clamp that secures the cards and the metal
access port covers to the chassis.
