3.8.1 Misleading Error Message Displayed During Installation
During installation of Tru64 UNIX Version 4.0F software on a DEC 7000
system, the following message might appear on the console screen:
prom_saveenv: console returned illegal value
You should ignore this message and follow the instructions displayed on the
screen by the installation process.
3.9 AlphaPC 164 Systems
During an initial installation of Tru64 UNIX Version 4.0F software on some
AlphaPC 164 family systems, the installation procedure might hang while
setting the console environment variables prior to rebooting the system with
the new software. The problem does not occur during an update installation
because console environment variables are not reset.
This problem is due to a limitation in the console firmware for the systems
on which it is observed. The use of the consvar command, or attempts to
modify parameters in the bparm subsystem through use of the sysconfig
-r command also cause these systems to hang. To avoid this problem,
change console environment variables directly at the SRM console prompt
instead of through the privileged kernel interfaces.
If your AlphaPC 164 family system hangs during initial installation, you
should power cycle the system and then set the console environment
variables to reflect the correct boot device and boot mode. When you reboot
the system, the installation procedure will continue with system
configuration.
For example, if the system software is installed on the disk connected as unit
0 on SCSI bus 0 (that is, on rz0), then enter the following commands when
the system powers up to the SRM console prompt ( >>>):
>>> set bootdef_dev dka0
>>> set boot_osflags A
>>> set auto_action boot
The next time the system powers up, it will automatically boot from the
freshly-installed disk and prepare to come up in multiuser mode. You can
boot immediately from the console prompt by entering the boot command,
or you can power cycle the system.
