3.4 Software Conﬁguration

Two ﬁrmware programs have been loaded into the AlphaPC64 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 Windows NT. The AlphaPC64 system has been conﬁgured to start the

Windows NT ARC ﬁrmware by default.

The serial ROM ﬁrmware uses a value stored in the nonvolatile RAM of the

real-time clock to determine which ﬁrmware image to load. Once the Windows

NT ARC ﬁrmware is running, you can switch to the debug monitor ﬁrmware.

3.4.1 Starting Windows NT ARC Firmware

Start the Windows NT ARC ﬁrmware using the following procedure:

1. Verify that the jumper from J16–2 to J16–3 is inserted, allowing the ﬂash

ROM to be written. If the Windows NT ARC ﬁrmware is unable to write to

ﬂash ROM, it prints the

device error

message and stops.

2. Verify that the jumper from J3–25/26 is installed (see SP7 on the board).

The presence of the jumper at J3–25/26 forces the serial ROM ﬁrmware

to load the alternate image selected by the value in the nonvolatile TOY

RAM. The absence of this jumper overrides the value stored in the TOY

RAM and causes the ﬁrst image, the debug monitor, to be loaded.

3. Turn on the power to the AlphaPC64. After the power-up diagnostics are

run, the ARC console boot menu appears on the graphics display.

If the ARC console boot menu does not appear, check the output of COM1

for error messages and review your hardware conﬁguration.

You are ready for software installation. Refer to the Alpha Microprocessors

Evaluation Board Windows NT 3.51 Installation Guide for instructions.

3.4.2 Going to the Debug Monitor from Windows NT ARC Firmware

You may use either of these two methods to access the debug monitor from the

Windows NT ARC ﬁrmware.

A. Use the ARC ﬁrmware menus to choose the debug monitor.

1. At the Boot menu, choose Supplementary menu....

2. At the Supplementary menu, choose Setup the system....

3. At the Setup the system menu, choose Machine speciﬁc setup....

4. At the Machine speciﬁc setup menu, choose Debug Monitor.
