AlphaPC 164UX/BX Motherboard Windows NT User’s Manual

This document is the User's Manual for the Samsung AlphaPC 164UX/BX Motherboard, designed for computing systems based on the AlphaTM 21164 microprocessor and Digital Semiconductor 21174 core logic chip, primarily for use with Windows NT.

The manual details the motherboard's features, including its microprocessor, core logic, memory specifications (32MB to 3GB SDRAM with ECC), caching, and integrated I/O capabilities (PCI, ISA, Ethernet, SCSI, and standard ports). It also outlines the key differences between the 164UX (which includes Ethernet LAN and Ultra Wide SCSI controllers, and offers 2MB/4MB L3 cache) and the 164BX (which lacks these controllers and has a 2MB L3 cache), with the document focusing mainly on the 164UX.

Key sections provide instructions on:

• Jumper Configuration: Setting CPU speed, Bcache size, and boot options.
• Memory and Microprocessor Configuration: Installing and upgrading SDRAM memory and increasing microprocessor speed.
• Windows NT Setup: A comprehensive guide to installing and configuring Windows NT, including navigating the ARCSBIOS firmware, setting system parameters, and preparing for installation.
• Technical Reference: Pinouts for various connectors (PCI, ISA, DIMM, EIDE, etc.), ISA interrupt assignments, and I/O address maps.
• Troubleshooting: Steps for diagnosing hardware startup issues (e.g., no video, keyboard errors), explanations of beep codes and POST codes, and details on the "Safe ARCSBIOS" recovery mechanism.

Additionally, it lists supporting product vendors for components like memory and power supplies, and provides contact information for technical support and related documentation.
