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 Alpha 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 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. Observe antistatic precautions. 2. Align the heat-sink holes with the threaded studs on the ceramic package. 3.
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 EIDE IRQ15 EIDE 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.

Basic Alpha SRM Console Command Descriptions 7.2 Basic Alpha SRM Console Command Descriptions This section describes the following basic Alpha SRM Console commands that are necessary to boot the Tru64 UNIX operating system: • arc • boot • deposit • examine • fwupdate • set • show The Alpha SRM Console offers additional commands. For a complete list of Alpha SRM Console commands, enter help at the Alpha SRM Console prompt (>>>).
Basic Alpha SRM Console Command Descriptions arc Loads and runs the AlphaBIOS firmware update utility from a diskette.
Basic Alpha SRM Console Command Descriptions boot Initializes the processor, loads a program image from the specified boot device, and transfers control to the loaded image. Syntax boot [-file ] [-flags [,]] [-protocols ] [-halt] [] Arguments A device path or list of devices from which the firmware will attempt to boot. Use the set bootdef_dev command to set an environment variable that specifies a default boot device.
Basic Alpha SRM Console Command Descriptions Description The boot command initializes the processor, loads a program image from the specified boot device, and transfers control to that image. If you do not specify a boot device in the command line, the default boot device is used. The default boot device is determined by the value of the bootdef_dev environment variable. If you specify a list of devices, a bootstrap is attempted from each device in the order in which the device is listed.

Syntax examine [-{b,w,l,q,o,h,d}] [-{physical, virtual, gpr, fpr, ipr}] [-n ] [-s ] [:] Arguments : The optional device name (or address space) selects the device to access. The address specifies the first location to examine within the current device. The address can be any legal address specified.
Basic Alpha SRM Console Command Descriptions examine Command Option Description -ipr References internal processor register address space. -n Specifies the number of consecutive locations to examine. -s Specifies the address increment as a hexadecimal value. This option allows you to override the increment that is normally derived from the data size. Description The examine command displays the contents of the specified address, such as a memory location, register, device, or file.
