3.4.3 Returning to Windows NT ARC Firmware from the Debug Monitor

You can use one of the following methods 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 Alpha PCI 64–275

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:

The Alpha PCI 64–275 uses the same ﬁrmware as the AlphaPC64, so the ﬁrmware

prompts may appear as
