FLOPPY_CSP_V50A Tru64 UNIX V5.0A Single Byte Corruption Patch

TITLE: FLOPPY_CSP_V50A Tru64 UNIX V5.0A Single Byte Corruption Patch Copyright (c) Compaq Computer Corporation 2000. All rights reserved. PRODUCT: Tru64 [R] 5.0A SOURCE: Compaq Computer Corporation ECO INFORMATION: ECO Name: floppy_CSP_v50A ECO Kit Approximate Size: 184KB Kit Applies To: Tru64 5.0A ECO KIT SUMMARY: This ECO kit contains a solution, in the form of a patch, for the following issue: Compaq has advised owners of DS10, DS10L, ES40 AlphaServers, and XP900 AlphaStations that Compaq has determined in laboratory testing that there is a theoretical possibility that during read and write operations to the floppy disk on these systems, a single byte of data may be inaccurately read or written without notice to the user or system. The potential for this anomaly exists only if floppy disk read or write operations are attempted while there is extremely heavy traffic on these Alpha systems' internal input/output busses. Although Compaq has observed the anomaly only in laboratory tests designed to create atypical system stresses, including almost constant use of the floppy disk drive, Compaq has informed owners of the remote possibility that the anomaly could occur so that they may take precautions to prevent it. Compaq recommends the solution be installed by all DS10, DS10L, ES40 AlphaServers, and XP900 AlphaStation customers. The potential floppy anomaly affects VS10 AlphaStations, which are not supported by Tru64 UNIX. The Compaq web site at: www.compaq.com/support/ds_es_floppy/ provides a recommended workaround that should be used if you are concerned about the potential anomaly on this unsupported configuration. INSTALLATION NOTES: Copy the ECO kit to the target system. Unzip the file using gunzip. The patch is installed manually using the installation instructions included in the README contained in the ECO kit. Please read through the instructions prior to installing patches on your system. Installation of this ECO kit requires Tru64 UNIX 5.0A and Patch Kit 1 (BL01) be installed. SUPERSEDED PATCH LIST: None. KNOWN PROBLEMS WITH THE PATCH KIT: None.
