HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

The code required to make these changes may be delivered by multiple patches. As a result, you
may see the same description listed under more than one patch.
Also, because Tru64 UNIX patch kits are cumulative, each new kit contains all of the fixes and
enhancements that were provided in earlier kits. This can result in changes to components being
made multiple times. For example, a patch may deliver several versions of the same driver. In
such cases, the latest version is installed on your system.
Each patch provides fixes to subsets of the operating system. Subset names (listed in italic font
in the following lists) consist of three parts; for example, for subset OSFACCT540, the OSF
indicates that the subset is part of the base system, the ACCT indicates a category, and the 540
indicates that the subset belongs to the Version 5.1B operating system.
