The bootable tape feature has been enhanced to support:

See the btcreate and btextract reference pages for more information.

All problem reports entered before July 1996 have been resolved.

3.3    Console

The syslogd daemon now has an internal switch to disable and enable messages to the console. This feature is available through the -s flag on the syslogd command line or by running the following command: /usr/sbin/syslog.

3.4    VMEbus Example Device Driver Upgraded

The VMEbus example device driver, /dev/dmaex, has been upgraded to single binary module technology and enhanced with new capabilities, including programmed I/O and block-mode DMA transfers. The driver and a new user program that exercises the driver are included in C source format on the DIGITAL UNIX CD-ROM. The upgraded example is in the DIGITAL UNIX manual Writing VMEbus Device Drivers.

3.5    Maintenance

This version provides maintenance for the following system functional components:

It also provides maintenance for the following system hardware support components:

For specific descriptions of the maintenance included in this version DIGITAL UNIX, see the DIGITAL UNIX Version 4.0B CLD Fixes document and similar documents included in this kit. They are located on line on the DIGITAL UNIX Version 4.0B Operating System, Volume 1 CD-ROM in the following directory: 

/mnt-point/DOCUMENTATION/TEXT
 

Replace mnt-point with the name of the directory where your CD-ROM is mounted.

3.6    Date Command Enhanced for Year 2000 Support

The date(1) reference page has been amended to include information on setting the system date past the year 1999. You can use the new arguments for testing your software for potential century rollover problems.

3.7    Installation Process Enhanced

The installation cloning feature introduced in DIGITAL UNIX Version 4.0 has been enhanced to allow unattended installation cloning at client systems. Also, the installation process now supports the execution of user-supplied scripts. For more information about these and other enhancements to the installation process, refer to the Installation Guide.

3.8    Ladebug Debugger Updated

An updated version of the Ladebug Debugger is supplied with this release. The release notes for this version of Ladebug are located in the OSFLDBDOC410 and IOSLDBDOC410 subsets on the DIGITAL UNIX Version 4.0B Operating System, Volume 1 CD-ROM and can only be accessed when Ladebug is installed. After installation, the release notes can be found in the following location: 

/usr/doc/ladebug/ladebug-relnotes.txt
 

3.9    Netscape FastTrack Server Version 2.0

This release of DIGITAL UNIX contains Version 2.0 of the Netscape FastTrack Server, an easy-to-use entry-level Web server designed to let you create and manage a Web site. To install FastTrack on your system, perform the following steps:

  1. Log in to the root account on your system.

  2. Insert Volume 1 of the Associated Products CD into your CD-ROM drive and mount the drive as a read-only device. The following example assumes that your CD-ROM device is located at /dev/rz4c and that you wish to mount it under a pre-existing directory labeled /mnt. 

    # mount -r /dev/rz4c /mnt
 

  3. Change your directory to the FastTrack kit directory: 

    # cd /mnt/ALPHA/Netscape_FastTrack_Server
 

  4. Read the readme.txt file. This file contains information from Netscape about the FastTrack kit. Since you will be installing FastTrack from a DIGITAL UNIX CD, you can ignore steps 1-5 of the installation instructions, which pertain to installing from a Netscape CD.

  5. Begin the installation by running the ns-setup installation program and following the instructions in the readme.txt file: 

    # ./ns-setup
 

    The installation program will query you for several pieces of information and then install FastTrack under a directory on your system that you specify. The Netscape installation program recommends /usr/ns-home as a default installation location. However, DIGITAL recommends that you choose a default location of /usr/opt/ns-home instead. A directory created under /usr/opt is typically a more suitable place than one directly under /usr for software (like FastTrack) that creates and writes to files in its installed area.

3.10    Netscape Navigator Gold Version 3.0

This release contains Version 3.0 of the Netscape Navigator Gold World Wide Web browsing program. You can invoke Netscape Navigator Gold from a CDE desktop icon, located in the CDE Application Manager's Desktop_Apps folder. Netscape Navigator Gold can also be invoked directly from the command line by running /usr/bin/X11/netscape.

You can access detailed help on Netscape Navigator Gold through the help menus.

A DIGITAL UNIX home page can be found in /usr/doc/netscape in the the file named Digital_UNIX.html. The home page contains links to helpful documentation, including a local copy of the Netscape Navigator User's Handbook (consider adding this link to your list of Netscape bookmarks).

The DIGITAL UNIX Installation Guide contains information on how to set up Netscape. See Chapter 6, which covers postinstallation setup tasks.

3.11    Performance Manager Updated to Version 2.1A

Performance Manager version numbering has been synchronized with the operating system. Version 4.0B supercedes Version 2.1A.

Performance Magager Version 4.0B is a maintenance update of Version 2.1A, which included the following enhancements:

The release notes for Performance Manager are included on the DIGITAL UNIX Associated Products CD-ROM Volume 1. The PostScript file is PMGR410_RELNOTES.ps and the text file is PMGR410_RELNOTES.txt.

3.12    Worldwide Language Support Enhanced

Catalan Support was introduced in DIGITAL UNIX Version 4.0, but for that release the system administrator was required to select Spanish from the Worldwide Language Support Installation selection menu before selecting the Catalan support subset. In DIGITAL UNIX Version 4.0B, an entry for Catalan has been added to the selection menu. Now there are separate selection entries for Spanish Support and Catalan Support.

In addition, two subset descriptions (IOSWWCDEDT405 and IOSWWPRINT405) have changed and several worldwide language support subsets have been added to support the following languages:

For a full listing of the additional subsets and new descriptions, refer to the Installation Guide.

3.13    New Processor Support

The following new processors are supported in DIGITAL UNIX, Version 4.0B:
