3 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.

Password Bypass Jumper (CF3) 3.3 Password Bypass Jumper (CF3) 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. This disables the AlphaBIOS password verification and enables the user to set up or start up their system without the AlphaBIOS password. Password Bypass also clears the password. 3.

5 Memory and Microprocessor Configuration For higher system speed or greater throughput, you can upgrade SDRAM memory by replacing DIMMs with those of greater size. When configuring or upgrading SDRAM, observe the following rules: • Each DIMM must be a 168-pin unbuffered version and have a frequency of 100 MHz. • All DIMMs must be of equal size if they are in the same bank. 5.1 Configuring SDRAM Memory Although not an exhaustive list, Table 5–1 lists the tested SDRAM memory configurations available.

Increasing Microprocessor Speed 5.3 Increasing Microprocessor Speed This section describes how to complete the following actions to increase microprocessor speed: • Replace the 21164 microprocessor with an Alpha chip that has a higher speed rating. • Reconfigure the clock divisor jumpers. 5.3.
Increasing Microprocessor Speed 5.3.3 Removing the 21164 Microprocessor Remove the microprocessor currently in place at location U40 by performing the following steps: 1. Unplug the fan power/sensor cable from connector J18 (see Figure 2–1). 2. Remove the four 6-32 X 0.875-inch screws that secure the fan and fan guard to the heat sink. 3. Remove the fan and fan guard. 4. If the sink/chip/fan clip is used, remove it by unhooking its ends from around the ZIF socket retainers. 5.
Increasing Microprocessor Speed 6. Install the heat sink and heat-sink fan as directed in the following steps. A heatsink/fan kit is available from the vendor listed in Appendix A . Refer to Figure 5–1 for heat-sink and fan assembly details. Figure 5–1 shows the Fan/Heat-Sink Assembly on AlphaPC 164LX. Figure 5–1 Fan/Heat-Sink Assembly Screw, 6-32 x 0.875 in Qty 4 Guard, Fan Fan Clip, Heat Sink/Chip/Fan Nut, Hex, 1/4-20, 2011-T3 Aluminum, 0.
Increasing Microprocessor Speed 2. Wearing clean gloves, pick up the GRAFOIL pad. Do not perform this with bare hands because skin oils can be transferred to the pad. 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 anodized, hot-water-sealed, 6061-T6 aluminum. The nut material is 2011-T3 aluminum (this grade is critical). Perform the following steps to attach the heat sink: 1.
6 Interrupts and ISA Bus Addresses This section lists the system and I/O interrupt assignments. It also lists the physical AlphaPC 164LX I/O space assignments. 6.1 Interrupts Table 6–1 lists each AlphaPC 164LX ISA interrupt and its source.
ISA I/O Address Map Table 6–1 ISA Interrupts (Continued) Interrupt Number Interrupt Source IRQ13 Available IRQ14 IDE IRQ15 IDE 1 The # symbol indicates an active low signal. 6.2 ISA I/O Address Map Table 6–2 lists the AlphaPC 164LX ISA I/O space address mapping.
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 80016 provides this function. Writing a 0 to this location enables the lower 512KB of flash. Writing a 1 to this location enables the upper 512KB of flash.
