AlphaServer DS20E / AlphaStation DS20E Release Notes

This document provides hardware release notes for the Compaq AlphaServer DS20E and AlphaStation DS20E, published in April 2000.

Key points include:

• Minimum Requirements: It lists the specific minimum software and firmware versions required for various operating systems (Tru64 UNIX, OpenVMS, Linux) and utilities (SRM, AlphaBIOS, Compaq Analyze).
• False Errors: Users can safely ignore a "False I²C Bus Error" displayed on power-up, as it's a normal startup condition.
• Operating System Notes (Tru64 UNIX): Details several issues including environmental status errors, inaccurate logging of fan and redundant power supply failures, specific "platform not known" messages to ignore on boot, and the lack of support for integrated Adaptec devices and USB on V4.0F.
• Operating System Notes (OpenVMS): Also notes the lack of support for Adaptec devices and USB. It highlights incorrect reporting of redundant power supply failures in systems with fewer than three power supplies, advising users to check the system error log for accurate diagnosis.
• SRM Console Notes: Explains that the console's show config command may list unsupported devices (USB, Adaptec). It also details a false report from the show power command after reinserting a power supply, recommending a system power cycle to clear the error.
• Application Development: Directs developers to consult the Tru64 UNIX Release Notes and specific Web sites.
• Compaq Analyze: Recommends installing Compaq Analyze for critical error event translation and analysis, providing installation notes and download information.
• RMC Baud Rate: States that the Remote Management Console (RMC) requires the COM1 baud rate to be kept at 9600 (factory default) for console callbacks; changing the baud rate requires disabling the RMC first.
