Cover Letter for VAXstationTM 3100, Model 76 System
EK-VMS31-CL

The following release notes apply to the VAXstation 3100 Model 76 system:
*

Mouse Performance—The mouse included with the VAXstation 3100 Model
76 system uses two “feet” (one for moving horizontally and one for moving
vertically) instead of a ball. For optimum performance with this type of mouse,

choose Pointer ... from the Session Manager’s Customize menu. Then, set the
mouse speed (Pointer Acceleration)in the Customize Pointer dialog box to Fast,
instead of Medium (whichis the default setting reqmred for a mouse with the
ball design).
Mouse performance, including improved diagonal movement, will be addressed

in a future version of DECwindows.TM Mouse performance on systems running

VMSTM Workstation Software (VWS)

iis unaffected.

Upgrading with SPX Graphics—If you upgrade your system to a VAXstatmn
3100 Model 76 with an SPX graphics option and the system fails to boot (that
is, if it crashes and generates a DECwindows-specific, fatal internal error), do
the following:
—

If you are booted into a cluster, contact the system manager and request

that the SYSGEN parameter SPTREQ be set to 2800.
—

If you are not booted into a cluster, do the following:
1.

Halt the system.

At the prompt (>>>), enter the following:
>>>

B/1

device~name

Substitute the device name of the system disk for device-name. For
example, to boot from a drive with a device name of DKA400, enter the
following command and press RETURN:
>>>

B/1

DKA400

(See VMS Installation and Operations: VAXstation 3100, MicroVAX

3100 Series for more information about device names and booting the
system.)
3.

At the next prompt (SYSGEN>), enter the following:
SYSGEN>

SHOW SPTREQ

If the value is 2800 or more (and the system failed to boot), submit a
QAR. If the value is less than 2800, enter the following:
U C

SYSGEN>

SET SPTREQ 2800

SYSGEN>

EXIT

The system should resume booting normally.

This behavior (system crash while upgrading with SPX Graphics) will

be corrected in a future release of the VMS operating system.

AUTOGEN—The default AUTOGEN parameters set LOCKDIRWT to 1. To

System Crash—If your system crashes and your subsequent ANALYZE/CRASH
and SHOW STACK commands generate a display in the stack that includes
SYSLOA+00D2C, ignore that specific output and reboot the system. The system
should resume normal operations. This behavior will be corrected in the next
maintenance release of the VMS operating system. A sample display follows:

avoid potential performance problems, set LOCKDIRWT to 0.
