either at the front OR at the back), onboard SCSI terminators will be activated to terminate that end of the
SCSI bus. When the board is sitting in the middle of the SCSI chain (i.e. devices connected both at the front
and at the back), onboard terminators will be automatically removed.
You can verify proper physical connection by executing the Openboot command probe-scsi. This command
transmits an inquiry command to SCSI devices connected to the system unit onboard SCSI interface. If the
SCSI device is connected and active, the target address, unit number, device type, and manufacturer name is
displayed. The example below identifies the probe-scsi output me

2.5.5 Creator Graphics Card
A Creator Graphics Card can be installed by Themis Computer on the USPIIi-1v/2c and USPIIi-1v/3. A
DB13W3 video output connector is available at the front, together with a Din-8 synchronization port for
stereo displays.
Note — Creator Graphics must be used in conjunction with a PS/2 or Sun keyboard and mouse. If the latter
are not attached to the USPIIi-1v board prior to power on, OpenBoot will redirect its text output to the
serial console and not to Creator Graphics
2.6 Configuring The VME Interface
Themis has implemented a variable and flexible VMEbus interface using both onboard jumpers, OpenBoot
PROM (OBP) commands, and OBP environment variables specific to the USPIIi-1v board.
The USPIIi-1v is typically re-configured when VMEbus boards are added, removed, or changed in the
chassis. Board configuration normally involves allocation of VMEbus master access address, interrupts, and
slave base address of the USP-2.
Only the VME SYSRESET function is configured by hardware jumpers. Consult Appendix B.2.1, "Baseboard
Jumpers," for details. All other VMEbus interface related options are configured using extensions to the Sun
OpenBoot PROM monitor program and are described in the “USPIIi-1v Software Manual”, Themis P/N
108966.
