Problem: Computer freezes at extension.
Possible
Solutions:
1) Try unplugging the Crescendo card and reseating it in
the PDS slot.
2) You may have a conflict with an extension that loads
early and changes low level processor control registers.
To identify which extension is causing a problem, do
the following:
• If you have RAM Doubler installed, insert the
RAM Doubler disk into the floppy disk drive
and run the RAM Doubler deinstaller program.
• Create a new folder on the desktop called
Disabled Extensions Folder. Except for the
Crescendo extension, move software
extensions like Disk Doubler, Speed Doubler,
and virus protection software from the
Extensions Folder (located inside the System
Folder) to the Disabled Extensions Folder on
the desktop.
• Restart the computer.
• If the computer boots normally, reinstall an
extension from the Disabled Extensions Folder
to the Extensions Folder and restart your
computer. Do this step with each subsequent
extension in the Disabled Extensions Folder
until you find the problematic extension.
Replace the offending extension with a newer
version or remove it from your system.
Problem: Computer freezes at desktop or at random.
Possible
Solutions:
This may be due to the hard disk driver being old,
corrupted, or incompatible with the new processor
upgrade. You may need to:
1) Reinstall the latest drivers for your hard disk drive
after the Crescendo extension has been loaded and
the new processor upgrade is running. Contact the
manufacturer of your hard drive or visit their website
for driver updates.
