Installation Instructions & Release Notes
REVERTING TO A PREVIOUS SOFTWARE VERSION
To revert to a previous version of 960L software, follow the same procedure outlined above
using the release CD for the desired software version. There is one special consideration:
When upgrading to Version 2.40, the software recognizes prior versions of user registers and
automatically converts them to a compatible format. The 960L software is not able to convert
back from later versions.
Therefore, when performing a "back-rev," erase all user registers before inserting the release
CD. It is recommended to save them first, noting the software version of the user registers.
Next, do a Factory Init.
To do this, follow the instructions below:
1. Power down the system, wait a few seconds, then power back up. As soon as the LARC2
receives power, go to Menu Mode by pressing and holding the PROGRAM and MACHINE
keys at the same time. Hold them until the following message appears:
Requesting menu mode from 960L . . .
Once the message appears, release the buttons. The 960L will take a little longer to boot
than normal. As soon as it is booted, a menu should appear on the LARC2. Ignore any
messages that concern locking the CD.
2. Select this item from the menu:
7) Erase User Registers & Restore Factory Default Settings
Once this process is complete, follow the installation instructions outlined on pages 4 and 5
using the release CD for the desired software version. A few messages will differ slightly.
When checking the software version (see Step 7 on page 5), please refer to the release notes
of the software version being installed to determine software revisions for the LARC2 and the
960L mainframe.
