Upgrading the OpenVMS VAX Operating System
7.1 Preparing to Boot from [SYSF]
7.1.1 Modifying Boot Command Procedures
Some VAX computers require a special command procedure to boot from [SYSF].
If you are performing an upgrade on one of the following VAX computers, you
must modify the boot command procedures, DEFBOO and dddGEN before
beginning the upgrade procedure:
VAX 8530, 8550, 8700, 8810, 8820-N
VAX 8820, 8830, 8840
To modify the boot command procedures, exit from the OpenVMS VAX operating
system (but do not shut it down) and enter the appropriate console mode. Make
copies of DEFBOO and dddGEN before you modify them. Name the copies
DEFBOO.SAV and dddGEN.SAV.
The upgrade and installation supplement for your VAX computer describes
the procedures for copying and modifying DEFBOO and dddGEN. Use these
procedures to modify DEFBOO and dddGEN so that they specify [SYSF] as the
directory from which to boot.
In DEFBOO, change the DEPOSIT command that sets boot flags in register 5
(R5) as follows:
DEPOSIT R5=F0000000
In dddGEN, change the DEPOSIT command as follows:
DEPOSIT R5 F0000001
7.1.2 VAX 8200, 8250, 8300, and 8350 Computers
If you are upgrading a VAX 8200, 8250, 8300, or 8350 computer, you must create
a boot command procedure that allows you to boot from the [SYSF] directory
before beginning the upgrade. The upgrade and installation supplement for your
VAX computer describes how to create this boot command procedure.
7.1.3 Configuring Devices
Because you rebooted your system with minimum startup, the system did not
automatically configure all devices. However, you might need access to some of
the devices to perform the upgrade.
To make sure you can access the devices that might be needed for the upgrade,
run SYSGEN to reconfigure the devices on the system and run STARTUP
CONFIGURE by entering the following commands:
$ RUN SYS$SYSTEM:SYSGEN
SYSGEN> AUTOCONFIGURE ALL
SYSGEN> EXIT
$ @SYS$SYSTEM:STARTUP CONFIGURE
7.2 Performing the Upgrade
This section describes how to start the upgrade procedure using VMSINSTAL.
You can type a question mark (?) for help at any time while running
VMSINSTAL.
The instructions refer to the source drive and the target drive, where:
• The source drive is the drive that holds the distribution kit.
• The target drive is the drive that holds the system disk.
