4.6.3.2 P64-B 
Arbitration 
The P64-B supports five PCI masters (the on-board gigabit ethernet controller, three slots on 
the 3-slot PCI Riser, and the P64H2).
 
All PCI masters must arbitrate for PCI access using 
resources supplied by the P64H2.
 
The host bridge PCI interface (P64H2) arbitration lines 
REQx* and GNTx* are special cases in that they are internal to the host bridge.
 
The following 
table defines the arbitration connections.

Arbitration 
P64-C supports five PCI masters (three slots on the 3-slot PCI riser, the embedded U-320 SCSI 
controller, and the P64H2).
 
All PCI masters must arbitrate for PCI access, using resources 
supplied by the P64H2.
 
The host bridge PCI interface (P64H2) arbitration lines REQx* and

Zero Channel RAID (ZCR) Capable Riser Slot 
The SCSI version of the SE7501WV2 server board is capable of supporting the following zero 
channel RAID controllers, the Intel® SRCZCR, SRCMRU and SRCMRX RAID Adapter and the 
Adaptec* 2000S RAID adapter. ZCR cards are only supported in the first slot of  the 3-slot PCI 
riser cards or the 1-slot riser cards used on the P64-C PCI segment.
