AlphaServer 800 UltraSCSI Operation

This document addresses an issue with AlphaServer 800 systems equipped with a 54-24803-02 motherboard, where an incorrect EEROM setting forces the on-board SCSI controller to operate in FAST10 mode instead of the intended UltraSCSI (FAST20) mode, potentially causing device slowdowns and disk errors. The document provides a detailed step-by-step procedure for utilizing the AlphaSystem Firmware Update CD (V5.3) and the \utility\eeromcfg program to load the correct settings and resolve the problem. Systems with the 54-24803-01 motherboard are not affected.
