1 Introduction to the Alpha PCI 64–275 The Alpha PCI 64–275 is a motherboard containing an Alpha 21064A microprocessor. The board supports the Microsoft Windows NT operating system through firmware in a flash ROM. In addition, the firmware contains a mini-debugger to assist you as you install the Alpha PCI 64–275 in your application. Note The Windows NT operating system is not included and must be purchased separately.

3 Additional Hardware Requirements Before turning on the power to your Alpha PCI 64–275, you must provide the following components. The components needed depend upon the intended use of the Alpha PCI 64–275 board. • A 275-W industry-standard PC power supply that includes a +3.3 V dc output • A terminal or a serial line connection to another system running a terminal emulation package You may want to provide a system enclosure that will accept a baby-AT-size motherboard (optional).
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.

Connect a 3.5-in diskette drive. The 34-pin diskette drive cable goes from connector J24 on your Alpha PCI 64–275 to the diskette drive. Attach a power connector to the drive.
. Observe the debug monitor messages that immediately follow when the Alpha PCI 64–275 is turned on. These messages describe your system configuration, version dates, and memory size, and conclude with the AlphaPC64> system prompt. 9. Verify the memory size and system configuration information displayed. 10. If you do not see the debug monitor messages, turn off the power to the Alpha PCI 64–275.

4.3 Starting Windows NT ARC Firmware If you plan to install the Windows NT operating system on your Alpha PCI 64–275, turn off the power to the Alpha PCI 64–275, and proceed with the following hardware configuration procedure: 1. Connect the keyboard cable to connector J33. 2. Connect the mouse cable to connector J34. 3. If you will be using any SCSI devices, such as a SCSI CD-ROM drive or hard disk, install the SCSI controller in any free PCI or ISA slot.
Use the following debug monitor commands to select Windows NT ARC Firmware and to verify the selection:1 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" "DEC OSF/1" "OSF" O/S type selected: "The Windows NT Operating System" ....
4.4 Returning from Windows NT ARC Firmware to the Debug Monitor You may use either of the following two methods to return to the debug monitor from the Windows NT ARC Firmware: • Turn off the power to the Alpha PCI 64–275, remove the jumper from J3-25 (SP7 on the module), and then turn on the power to the Alpha PCI 64–275. • Use the Windows NT ARC Firmware menus to choose the debug monitor, as follows: 1. At the Boot menu, choose Supplementary menu.... 2.
