The AlphaPC 264DP software is divided into the following categories:
•
Serial ROM code
•
Flash ROM code
•
Operating systems
4.11.1 Serial ROM Code
The serial ROM code is contained in a 512KB flash ROM. The serial ROM code ini-
tializes the system, which includes loading Debug Monitor or other code from the
flash ROM. The serial ROM code then transfers control to the code loaded from the
flash ROM.
The Mini-Debugger is also resident in the SROM. Switch 4 can be set on SW2 (see
Section 2.2) for CPU0 and CPU1 to trap to the Mini-Debugger. Connector J2 on the
daughtercard provides a terminal port for the Mini-Debugger.

The AlphaPC 264DP includes an industry-standard, 2MB flash ROM – AMD
AM29F016.
4.11.3 Operating Systems
The AlphaPC 264DP is designed to run Windows NT and Tru64 UNIX.
