2 Disk Premium Process Software Installation

The 2 disk Premium Process Software installation procedure can only be used on bonders that are running software versions 8-20-2-23, 8-28-2-23, 8-98-2-25 or later. Information such as MDP's and bond programs will normally be preserved on the hard drive (see “Notice” below). (It is still good practice to save all Process Programs and the MDP’s onto separate formatted

1.44M High-Density (HD) floppy disks in case of upgrade failure.)

1. From the GUI click on the Mode menu.

2. Click on .

3. Click on and select the appropriate responses to accept a reboot and installation.

4. Insert Disk 2 when prompted and select ENTER.

For the 8020:Follow the on-screen prompts that walk you through the GUI installation with the floppies. When prompted to "C HECK H ARD-D RIVE", reply “N.” When prompted

to "R EBOOT S YSTEM", remove the last floppy diskette from the drive, and then

reboot the machine by cycling power OFF. Wait at least 10 seconds before

powering ON the machine again.

For the 8028:Follow the on-screen prompts that walk you through the GUI installation with the floppies. When prompted to "C HECK H ARD-D RIVE", reply “N.” When prompted

to "C ONTINUE WITH I NSTALLATION", select "Y", then after the last disk is installed,

remove the last floppy diskette from the drive.

Note: The 8028 will reboot by itself.

5. Verify the correct Premium Process has been installed, by looking for “CSP” as one of the

looping trajectories available.

Notice:

K&S recommends you reply when you see this prompt:

DO YOU WISH TO CHECK THE TARGET HARD-DRIVE FOR BAD SECTORS?

THIS COULD TAKE A WHILE (y/n): “n”

If you reply you might be forced to reinstall the entire bonder software then restore the MDPs and recipes from backup if any sections of that hard-drive are repaired by that utility.
