AlphaPC 164UX Jumper Configuration The AlphaPC 164UX has one set of jumpers located at J28. These jumpers set the hardware configuration and boot options. Figure 2–1 shows the jumper location on the AlphaPC 164UX motherboard. Figure 3–1 shows the jumper functions for each group.
3.2 Bcache Size Jumpers (Option 14,15) The Bcache size jumpers are located at J28–27/28 (Option14) and J28–29/30 (Option15), as shown in Figure 3–1. The AlphaPC 164UX-2/-4 is configured with 2MB/4MB of Bcache during production ; the other jumpers shown in Figure 3–1 (0,1) are for other implementations.
AlphaPC 164UX Connector Pinouts This section lists the pinouts of all AlphaPC 164UX connectors. See Figure 2–1 for connector locations. 4.1 PCI Bus Connector Pinouts Table 4–1 shows the PCI bus connector pinouts. Table 4–1 PCI Bus Connector Pinouts (Sheet 1 of 2)
Pins 1 through 84 are on the front side and pins 85 through 168 are on the back side. The AlphaPC 164UX uses BA1 as both BA1 and ADDR12. Therefore, four-bank DIMMs using ADDR<11:0> are the maximum size. (Two-bank DIMMs can use ADDR<12:0>.) Pull-down.

The AlphaPC 164UX motherboard ships with the ARCSBIOS firmware. This firm- ware initializes the system and enables you to boot the Windows NT operating sys- tem. The ARCSBIOS firmware resides in the flash ROM on the AlphaPC 164UX motherboard. 7.1.1 Navigating the ARCSBIOS Table 7–1 shows the keys used to navigate the ARCSBIOS and their function...
The upper right hand corner of the screen displays the speed that the AlphaPC 164UX is running. The first number is the clock speed of the system bus. The second number is the clock speed of the 21164 microprocessor. The remaining section of the bios screen are discussed below.
ARCSBIOS Setup. c. Memory Information. The Total Memory section displays the total amount of memory in the system in Kilobytes. The Free Memory section displays the amount of memory available to the operating system. The ECC Mem indicator tells if the memory in the system allows the system to use error correcting codes. The DIMM table shows what banks are populated with DIMMS and what size they are.
ARCSBIOS Setup. Caution : Changing the environment variables may cause Windows NT to fail to boot. There are 4 selections on the Environment Variable menu. Edit Environment Vari- able Set allows you to change an existing environment variable set. Select Default Environment Variable Set allows you to select which boot selection will boot auto- matically if the autoload feature is enabled.
ARCSBIOS Setup. The option to Enable X86 Emulation is set default to Yes. This option allows an operating system to use the X86 emulator built into the ARCSBIOS to emulate the video BIOS built into most video adapters. The DIMM Bank Memory type set- tings can allow you to get a performance increase if you know the manufacturer of the SDRAM chips on your DIMMs.
7.2.7 Add-in Board Utilities This option allows you to run configuration utilities for add-in cards that have been ported to the AlphaPC 164UX motherboard. At the time of printing there are no util- ities available. 7.3 Upgrading the ARCSBIOS Firmware.
