4 Starting Up and Using the Alpha PCI 64–275

After all the required hardware components have been assembled, connect

them to the Alpha PCI 64–275 by using the module connectors. For a standard

system (without Windows NT), follow the procedure listed in Section 4.1. For a

system using Windows NT, perform the additional steps listed in Section 4.3.

For information about the location of the module connectors, refer to the

System Jumpers and Connectors chapter in the Alpha PCI 64–275 User’s

Manual.

Two ﬁrmware programs have been loaded into the Alpha PCI 64–275 1MB

ﬂash ROM. They are the debug monitor and the Windows NT ARC Firmware.

The debug monitor is a serial line monitor program used to perform software

and hardware debug functions. The Windows NT ARC Firmware is used to

load and boot the Windows NT operating system. The Alpha PCI 64–275

system has been conﬁgured to start the debug monitor by default. When the

debug monitor is running, you can switch to Windows NT ARC Firmware.

4.1 Starting the Debug Monitor

To start the debug monitor on your Alpha PCI 64–275, follow this procedure:

1. Connect a 9-pin serial port adapter cable to the COM1 connector at J32.

Insert the connector in the proper orientation, so that pin 1 on the cable

matches pin 1 on the board header (as indicated on the module).

2. Connect your terminal to the COM1 port by using a cable arrangement

appropriate to your terminal. Set the terminal to 9600 baud, 8 data bits,

1 stop bit, no parity.

3. Connect a power supply to the Alpha PCI 64–275 motherboard, as shown

in Figure 1, with standard power to J29 and J31 and with +3.3Vdc power

to J27 and J28. If you use Digital’s recommended power supply, connect

P8—J31, P9—J29, P11—J27, and P12—J28. J29 and J31 are mounted

inline to appear as a single 12-pin connector on the board, but accept two

6-pin plugs.

Caution

The four power connectors are not keyed, so pay particular attention to

Figure 1 when installing them.
