MicroVMS Release Notes Version 4.5B

This document, "MicroVMS Release Notes, Version 4.5B," published in March 1987, provides supplemental information for the MicroVMS Version 4.5B software, specifically for VAXstation 2000 and MicroVAX 2000 systems. It is intended for users who need to understand new features, problems, restrictions, and documentation changes before installing or upgrading.

The document is structured into three main chapters:

1. Differences Between Version 4.5 and Version 4.5B: This chapter details changes to device support (including four serial ports, monochrome display, diskette/hard disk drives, TK50 tape drives, and DESVA Ethernet controller), updates to system services ($GETSYI) and DCL commands (INITIALIZE for RX33 diskettes), and information on VAXstation 2000/MicroVAX 2000 I/O space and disk driver behavior.
2. Problems and Restrictions: This section highlights known issues and limitations, such as XDELTA debugger behavior, the static nature of device configuration at boot (requiring reboots for new expansion devices), recommendations for starting error logging, and specific constraints related to the TK50 tape cartridge drive (e.g., data transfer size limits, lack of datacheck and error retry support, spurious messages). It also notes a restriction on the bell character in the VAXstation 2000's integrated graphics window and instructions for printing to LA50 hardcopy terminals.
3. Notes to Published Documentation: This chapter provides corrections and additions to existing MicroVMS manuals, including the MicroVMS User's Manual (regarding floppy disk formatting) and the MicroVMS VAXstation 2000/MicroVAX 2000 Installation Guide (correcting the number of diskettes in the base kit). It also adds a section on using standalone BACKUP to the MicroVMS VAXstation 2000/MicroVAX 2000 Operations Guide.
