Typical applications: Multi-processor VME systems, turbine control, industrial data acquisition, military and aerospace embedded control

1. Pre-installation Preparation

Shut down the whole VME chassis and disconnect rack power. Wear ESD protection such as an anti-static wrist strap before touching the board.

Confirm that the backplane is a dual P1/P2 VME64 backplane.

Prepare accessories: monitor, PS/2 keyboard, CF card or IDE storage device, Ethernet cable, and serial cable if required.

Inspect jumpers: E4 for CMOS password clearing; E10 for CMOS battery enable; E15 for BIOS normal mode or boot block programming mode.

Check the forced-air cooling system. Fit blank filler panels on vacant slots to maintain proper airflow.

2. Hardware Installation

Slot selection: Install the board in Slot 1 when this SBC works as the VME system controller. Use other slots if a separate board takes the system controller role; no additional jumper setting is needed for system controller functionality.

Align the board with chassis guide rails and insert it gently to fully engage the P1 and P2 connectors.

Tighten front panel screws securely for vibration resistance.

Connect front-panel peripherals: VGA monitor, PS/2 keyboard, dual Ethernet cables, serial cable, USB device and PMC module if installed.

Power up the chassis once all connections are secured.

3. BIOS Configuration (Phoenix BIOS)

Access the BIOS menu with the specified hotkey during POST.

Main menu: Set system date and time, detect IDE storage media including CF, DOM and HDD, and configure the QuickBoot option.

Advanced menu: Enable or disable PCI IDE, USB, serial ports, watchdog timer and timer functions; configure IRQ and PCI interrupt mapping.

Boot menu: Define boot sequence priority among Floppy, IDE HDD, Onboard Flash and Network PXE.

VME bridge configuration: Set Universe II PCI-to-VME window, A24/A32 address range, D32/D64 transfer, byte swap and master/slave operating mode.

Save BIOS changes and reboot the board.

CMOS reset procedure: Power off the chassis, short the E4 jumper, apply power briefly, power off again and remove the jumper to clear CMOS data and password.

4. Operating System & Driver Deployment

Supported operating systems: VxWorks, QNX, Linux, Windows NT, Windows 2000, Windows CE.

Deploy VMIC BSP (VMISFT-7419 or VMISFT-9420) for real-time operating systems.

Install drivers for the on-board Intel 82559 Ethernet controller and AGP video controller.

Load the VME access library to support VMEbus read/write operations, interrupt processing and mailbox communication.

Configure non-volatile SRAM, watchdog timer and three 16-bit programmable timers through driver interfaces or application APIs.

5. VMEbus Runtime Configuration

Configure the VME address map, transfer width and MBLT64 mode according to the specifications of other VME slave modules.

Define VME interrupt levels and vector mapping.

Perform communication tests between this board and other VME modules under master and slave modes.

Activate the watchdog function: set the timeout interval and fault response action (system reset or interrupt trigger) for safety-critical control applications.

6. Diagnostic & Verification

Monitor front-panel LED status: power indicator, CPU thermal throttling indicator and storage activity indicator.

Execute POST self-test and on-board diagnostic tools.

Validate storage booting, Ethernet link status, serial communication and PMC expansion functionality.

Run loaded tests to verify VME data transmission and interrupt response.

Document BIOS settings, address mapping schemes and driver versions for backup purposes.
