CHAPTER 1 Overview
1.1 INTRODUCTION
The SFPCI-VME series of products provide a PCI-to-VMEbus interface, and the
capability of handling PCI master and slave functions. In addition, the series provide
VMEbus arbiter function, built-in DMA engine on board, as well as other system
controller functions of the VMEbus as described in the following sections.
The major components of the SFPCI-VME product come in two categories:
•The hardware component is made up of a PCI interface, a VMEbus interface, a flat
cable, and optional VME card cage including power supply and back-plane for
integrating the VME boards.
•The software component is an optional driver that is installed in the Solaris 2.x. It
enables users to retain their existing VMEbus drivers and transparently migrate their
present VMEbus subsystem to a PCI-Based SPARC platform.

1.3 GENERAL DESCRIPTION
The SFPCI-VME series is a PCI-to-VMEbus adapter allowing master and slave
accesses between these two host busses. In addition, VMEbus masters and slaves may
carry out information transfer with each other without stepping on the PCI bus.
A VMEbus master to PCI slave access takes place in a specified 1 MB “window,” via a
mapping register. A24 and A32 VMEbus accesses are also supported.
The PCI bus master to VMEbus slave addressing is accomplished in accordance with
the PCI addressing scheme. Internal mapping registers inside the SFPCI-VME series are
used to access the entire 4 GB of PCI bus address space. SFPCI-VME can transfer data
from/to VME bus upto 60-70Mb/sec, and supports the following address and data
transfer modes.
- A32/A24/A16 Master and Slave
- D64 (MBLT)/D32/D16/D08 Master and Slave
- BLT, ADOH, RMW, LOCK

2.2 SF_PCI Card Installation
Before you start with the installation, you may refer to system owner’s guide for the
instruction how to install PCI card to Sun system. The Sun doc is online and available at
the web site www.sun.com
Follow these instructions:
- Power off the system.
- Remove the side access cover.
- Attach the wrist strap.
---------------------------------------------------------------------------------------------------------------------
Caution - Use proper ESD grounding techniques when handling components. Wear an antistatic
wrist strap and use an ESD-protected mat. Store ESD-sensitive components in antistatic bags
before placing them on any surface.
---------------------------------------------------------------------------------------------------------------------
- Install the PCI card as follows
a. Position the PCI card into the chassis.
b. Lower the PCI card connector so that it touches its associated PCI card slot on
the motherboard.
c. Guide the PCI card back panel into the chassis backpanel.
d. At the two upper corners of the card, push the card straight downward into the
slot until the card is fully seated.
e. Using a Phillips-head screwdriver, replace the screw securing the card bracket
tab to the system chassis. Replace the side access cover.
2.2.1 Install SF_PCI Card to Sun Microelectronics (SME) Ultra AX SPARCengine
The Ultra AX SPARCengine provides 4 PCI slots. The two 64 bit connectors are PCI
bus A and the other two, hardwired with internal devices are PCI bus B. You can install
PCI short card to any available PCI slot, but for best performance, the PCI short card
should be installed in 64bit PCI slot (PCI bus A).

2.2.3 Install SF_PCI Card to Sun Ultra 5, Ultra 10
The Sun Ultra 5 and Ultra 10 have 3 and 4 32 bit PCI slots respectively for expansion.
PCI-VME can be installed in any available PCI slot without any restriction. PCI-VME
card will detect Ultra5/10 PCI bus and adjust automatically to support 32 bit. The 64 bit
portion on PCI-VME card is not used.
VME space can be mapped to full size 2Gig because a separated second bus is used to
support on-board devices.

There is total 10 PCI slots available on the Ultra 450 system. You can install PCI Card
to any PCI slot except the 3.3V slot (slot 4,5 and 6). It is also not recommended to
install PCI short card in slot 10. This slot is shared with to the internal devices such as
SCSI and network. Any other slot can be used.
FIGURE 11 Ultra 450 Mother Board and PCI slot location
For best performance, the PCI short card should be installed in slots supported by
different buses and different PCI-UPA bridges. Slot 7,8,9 share the same PCI bus F and
slot 1,2 and 3 share the same PCI bus D. This means if you have other devices already
installed in slot 1, 2 or 3, you should install the PCI short card to the slot 7, 8 or 9.

2.2.7 SF_PCI card Installation on Sun Blade 1500
There are two bus segment for total of five PCI slots. PCI0, PCI1, PCI2, and PCI3 are
under one PCI segment while PCI4 is under another.
Slot 0 might be occupied by pre installed FireWire and USB card. This will leave a total
of 4 PCI slots available. And if one of the 4 PCI slot is used to install a graphic card
such as a XVR-100, this will further reduce the available PCI slots to 3. The following
scheme is an example of PCI slot assignment, and had been tested for SF_PCI cards.
PCI 0: FireWire USB card
PCI1:
PCI2: SF_PCI card
PCI3:
PCI4: XVR-100 Graphic card
In fact, with FireWire USB card at PCI0 and XVR-100 at PCI4, any one of the
remaining PCI slots (PCI1, 2, 3) can be installed with SFPCI, and tested to work.

2.3 VMEbus Interface Board Installation
The SF_VME card should be installed in slot 1as a system controller.
There are a total of up to six VMEbus slots available in the Solflower VMEbus card
cage SFVMEB1. Aside from the slot occupied by the SF_VME VMEbus interface
board, all of the other slots are available for “customer owned” VMEbus peripheral
boards. Plug in these boards and their associated cables as appropriate.
Since the Solflower’s VMEbus card cage comes with five cover plates from the factory,
make sure that all of the unused VMEbus slots are covered in order to maintain FCC
compliance and proper air flow.

2.4 Cable Installation
Check the pins of the connector on both sides for broken or bent pins. If all pins are not
bent or damaged, position the Solflower SF_VME card cage adjacent to the SPARC
system, and install the cable between the PCIbus interface board and the VMEbus
interface board. Make sure that the connectors are locked
The cable is marked as to VME and to PCIbus and should not be resversed. Note: If the
cable from PCI to VME is correctly connected and the power of VME box is on, the
green LED on PCI card is on for ready
2.5 Boot Up System
After the system is powered up and rebooted, Solaris will probe all installed PCI devices
and display the attached device configuration
Now go to section Software Installation Chapter 5 for install Solflower’s pvme device
driver.
