Board Level Hardware Description

Every MVME166 is assigned an Ethernet Station Address. The address is $08003E2XXXXX where XXXXX is the unique 5-nibble number assigned to the board (i.e., every MVME166 has a different value for XXXXX).

Each module has an Ethernet Station Address displayed on a label attached to the VMEbus P2 connector. In addition, the six bytes including the Ethernet address are stored in the configuration area of the BBRAM. That is, 08003E2XXXXX is stored in the BBRAM. At an address of $FFFC1F2C, the upper four bytes (08003E2X) can be read. At an address of $FFFC1F30, the lower two bytes (XXXX) can be read. The MVME166 debugger has the capability to retrieve or set the Ethernet address. So does the MVME166 BootBug.

If the data in the BBRAM is lost, the user should use the number on the VMEbus P2 connector label to restore it.

The Ethernet transceiver interface is located on the MVME166 main module, and the industry standard connector is located on the MVME712X transition module.

Support functions for the 82596CA are provided by the PCCchip2. Refer to the 82596CA user’s guide for detailed programming information.

SCSI Interface

The MVME166 provides for mass storage subsystems through the industry- standard SCSI bus. These subsystems may include hard and floppy disk drives, streaming tape drives, and other mass storage devices. The SCSI interface is implemented using the NCR 53C710 SCSI I/O controller.

Support functions for the 53C710 are provided by the PCCchip2. Refer to the 53C710 user’s guide for detailed programming information.

SCSI Termination

The individual configuring the system must ensure that the SCSI bus is properly terminated at both ends. On the MVME166, the SCSI bus termination is provided on the main board. The terminators are enabled/disabled by a jumper. If the SCSI bus ends at the MVME166, the SCSI terminators must be enabled by installing the jumper. Refer to the jumper configuration tables in Chapter 2.

Local Resources

The MVME166 includes many resources for the local processor. These include tick timers, software programmable hardware interrupts, watchdog timer, and local bus timeout.
