AlphaPC 164LX Jumper Configuration The AlphaPC 164LX motherboard has two groups of jumpers located at J27 and J28, as shown in Figure 2–1. These jumpers set the hardware configuration and boot options. Figure 3–1 shows these jumper configurations. 3.1 CPU Speed Selection The clock synthesizer at location U47 makes it possible to change the frequency of the microprocessor’s system clock output without having to change the clock crystal.
Section 8.5. 3.5 Flash ROM Update Jumper (J28) When J28–2/3 are jumpered together (default), the flash ROM is write-enabled. When J28–1/2 are jumpered together, the flash ROM is write-protected. AlphaPC 164LX Jumper Configuration 3–3...

Increasing Microprocessor Speed 3. Place the GRAFOIL pad on the gold-plated slug surface and align it with the threaded studs. b. Attach the microprocessor heat sink. The heat-sink material is clear anod- ized, hot-water-sealed, 6061-T6 aluminum. The nut material is 2011-T3 alu- minum (this grade is critical).
Interrupts and ISA Bus Addresses This section lists the system and I/O interrupt assignments. It also lists the physical Alpha 164LX I/O space assignments. 6.1 Interrupts Table 6–1 lists each Alpha 164LX ISA interrupt and its source.

Table 6–2 ISA I/O Address Map Range (hex) Usage...
ISA I/O Address Map 6.2.1 Flash ROM Address Map The address range for the flash ROM is FFF8.0000–FFFF.FFFF. Flash space of 1MB is obtained by double mapping this 512KB space. FLASH_ADR19 register at I/O location 800 provides this function. Writing a 0 to this location enables the lower 512KB of flash.

Installing the Windows NT Operating System 7.2.1 Requirements You need the following hardware and software to install the Windows NT operating system on an Alpha 164LX system: • A 100MB or larger drive Note: For information regarding supported IDE/ATA hard drives, ATAPI CD-ROM drives, SCSI hard drives, CD-ROM drives, and controllers supported as boot/installation devices, see the README.TXT file on the Alpha 164LX AlphaBIOS Firmware diskette.
During the Windows NT installation procedure, you may be prompted for the type of com- puter that you have. For the Alpha 164LX system, choose DIGITAL AlphaPC 164LX. If AlphaPC 164LX is not one of the choices, choose “other” after you have inserted the AlphaPC 164LX Windows NT 4.0 Installation diskette. The following procedure supersedes the Starting Setup on a RISC-based Computer section of the Microsoft Windows NT installation guide.
Troubleshooting This chapter contains information about troubleshooting hardware and software during AlphaPC 164LX startup. 8.1 Password Bypass AlphaBIOS provides password protection. However, Password Bypass is provided for system setup or startup when the AlphaBIOS password is unavailable. Password Bypass is enabled by inserting jumper CF3 in the J27 System Configuration Jumper Block (see Figure 3-1).
Beep Codes 8. Reseat the DIMMs. 9. Replace the DIMMs. 8.3 Beep Codes The beep codes provide error information about the AlphaPC 164LX system. Table 8–1 lists and describes the beep codes. Table 8–1 Beep Codes Beep Code Description 1–2–3 This sequence represents the fail-safe booter startup.
1-2-3; that is, one beep and a pause, followed by two beeps and a pause, followed by three beeps. After the diskette activity light flashes, insert the AlphaPC 164LX AlphaBIOS Firmware diskette. The fail-safe booter will load and run AlphaBIOS from this diskette.
1. Power off your system. 2. Add jumper CF7 as described in Section 3.4. 3. Power on your system. 4. Insert the AlphaPC 164LX AlphaBIOS Firmware diskette into the diskette drive. 5. Proceed to Section 7.1.3 and follow the procedures.
