ISUALIZE
Personal Workstations are supplied with an integrated SCSI / 10BT/100TX
LAN combination (combo)board which is installed in PCI Slot 4. Even though the
SCSI/LAN combo board includes two controllers, only one PCI slot is necessary for
installation.
The LAN and SCSI controllers access the PCI bus through a PCI-to-PCI bridge. The SCSI
and PCI functions are contained within the Symbios Logic SYM53C875JE PCI-SCSI I/O
Processor chip.
Do not connect any devices to the Internal Narrow SCSI connector, and to the Internal
Wide SCSI connector at the same time. If you do, this results in a badly “terminated” SCSI
bus. In the HP V
ISUALIZE
Personal Workstations, only an Internal Narrow SCSI cable is
provided. The following diagram shows the SCSI/LAN Combo board connectors.

PCI Interface
The PCI interface operates as a 32-bit DMA bus master. The connection is made through
the edge connector. The signal definitions and pin numbers conform to the PCI Local Bus
Specification Revision 2.1 standard. The PCI interface conforms to the PCI universal
signaling environment for a 5 volt PCI bus.
