LINDY CPU Switch Dual Multi-Platform          Installation and Use 

Page 66 

 

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.
