AlphaServer 1000/1000A Model 5/xxx Owner's Guide Supplement

This document serves as a supplement to the AlphaServer 1000/1000A Owner's Guide, providing updated and supplemental information for the Model 5/xxx systems, specifically on system hardware and firmware. It details hardware changes such as memory module organization (with ECC on the modules, removing the need for dedicated ECC SIMMs), CPU card jumper settings, new beep codes, and additional environment variables for serial port modems. It also notes the removal of the onboard VGA controller in the latest motherboard revision and new functionalities for the Halt button.

A primary focus is the AlphaBIOS console, which replaces the ARC firmware interface. The document provides a comprehensive guide for Windows NT users on navigating and utilizing the menu-based AlphaBIOS for tasks like operating system installation, hard disk setup, system configuration display (including details on systemboard, PCI, EISA, SCSI, memory, and integrated peripherals), running maintenance utilities, setting password protection, and upgrading AlphaBIOS firmware. For OpenVMS Alpha and Digital UNIX users, it clarifies how to access AlphaBIOS from the SRM console when specific configuration utilities are required. The guide also includes troubleshooting suggestions for common hard disk problems.
