3.4.3 Returning to Windows NT ARC Firmware from the Debug Monitor

The following methods may be used to return to the Windows NT ARC

ﬁrmware from the debug monitor.

A. If you used item A in Section 3.4.2 to enter the debug monitor, then use

this procedure to return to Windows NT ARC ﬁrmware.

The ﬁrmware contained in the the serial ROM on your AlphaPC64

determines which ﬁrmware image is loaded from the ﬂash ROM at

power-up. The serial ROM ﬁrmware uses a value stored in the nonvolatile

RAM of the real-time clock to determine which ﬁrmware image to load.

At this point, you want the serial ROM to load the Windows NT ARC

ﬁrmware.

1. Use the following debug monitor commands to select Windows NT ARC

ﬁrmware, by writing the value 1 to the TOY RAM, and to verify the

selection:

AlphaPC64> bootopt nt

O/S type selected: "The Windows NT Operating System"

....Firmware type: "Windows NT Firmware"

AlphaPC64> bootopt

Predefined bootoptions are...

"0" "Alpha Evaluation Board Debug Monitor" "DBM"

"1" "The Windows NT Operating System" "NT"

"2" "OpenVMS" "VMS"

"3" "Digital UNIX" "UNIX"

O/S type selected: "The Windows NT Operating System"

....Firmware type: "Windows NT Firmware"

AlphaPC64>

2. Turn off the power to the AlphaPC64. Verify the presence of a jumper

at J3-25/26 (see SP7 on the board).

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.
