Upgrading The Lindy Cpu Switch's Firmware - Lindy 32351 Manual

IMPORTANT NOTE
The upgrade programs are DOS based to enable compatibility with the widest
range of operating systems. They run efficiently on DOS, Windows 3.X,
Workgroups, 95, 98, ME and Windows NT. The upgrades will take
approximately 10 minutes but vary slightly according to the LINDY CPU
Switch model and the speed of the PC. Upgrades run from PCs using
Windows 2000 will take very substantially longer due to the way that this
operating system handles the DOS programs. The upgrade will be reliable but
may take around 3 hours to complete!
Follow the instructions given on the screen to perform the upgrade. When the
upgrade is complete the program will confirm that the upgrade has been successful
and then quit.
Step 7 - Switch the UPGRADE key to the OFF position and cycle the power
Switch the UPGRADE switch on the rear of the LINDY CPU Switch to the OFF
position and disconnect the power. When the power is re-applied the LINDY CPU
Switch will operate using the new firmware.
Some useful issues to bear in mind when performing flash upgrades
The upgrade program rewrites the LINDY CPU Switch's firmware code. If the
upgrade process is interrupted then the LINDY CPU Switch will have invalid code
and will not be able to operate. It is therefore good practice to ensure that the
upgrade process is always fully completed. A partial or failed upgrade may be
rectified by performing another upgrade. If the upgrade process is interrupted
accidentally then you should immediately repeat the upgrade process without
moving switch 2 from the upgrade (ON) position. Switch 2 forces the LINDY CPU
Switch into flash upgrade mode and prevents the upgraded code from being run.
Running faulty or partially upgraded code may have unpredictable results and may
damage your LINDY CPU Switch or computing equipment. For obvious reasons, the
code that the LINDY CPU Switch uses to perform upgrades is not itself upgradeable
- a common problem on some flash upgradeable products that could effectively be
destroyed by a partial upgrade!
WARNING - Running faulty or partially upgraded code may have unpredictable
results and may damage your LINDY CPU Switch or computing equipment.
