Additional Rules for Card
Placement
PCI Slots, Bus Masters, and Bridges (Power
Macintosh 9500 and 9600 computers)
The Power Macintosh 9500 and 9600 have six
PCI slots. These slots are grouped in banks of
three, with each being controlled by a PCI Bridge
Chip. The first three slots are in one group and
the next three slots are in another.
A bus master card is a PCI card that controls the
data transfer to and from the Bridge Chip that
controls its group. The Digidesign MIX Core and
d24 cards are bus masters.
Other cards that act as bus master include:
• Expansion chassis host cards
• SCSI host bus adapters (HBA)
• Most video capture cards (including AVoption
and AVoption XL)
When configuring a Pro Tools system with a
Power Macintosh 9500 0r 9600 (without an ex-
pansion chassis), make sure to install Pro tools
Core cards on a separate PCI bridge from other
bus master cards.
When using an expansion chassis with a 9500 or
9600, install the chassis host card on a separate
bridge from other bus master cards (such as SCSI
HBAs and video capture cards).
Consult the manufacturer of your third-party
PCI cards to determine if they operate as bus
masters.
Systems Using an Expansion Chassis
If you are using an expansion chassis, refer to
the Pro Tools Expanded Systems Guide included
with your Pro Tools system for instructions on
connecting an expansion chassis to your com-
puter.
