Sonnet Technologies Crescendo_L2 Processor Upgrade - Manual (Page 69)

Problem: Computer loads extensions without freezing but
Crescendo extension has a red”X” through it.
Possible
Solutions:
Crescendo/L2 card is not completely seated in the L2
Cache Slot. Firmly press down on the card until it is
fully seated in the slot.
Problem: Computer freezes at extension.
Possible
Solutions:
1) Try unplugging the Crescendo card and reseating it in
the L2 Cache 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:
• Hold down the SHIFT key and restart your
computer until the start-up screen states:
“Extensions Turned Off.” This procedure will
disable the Crescendo card and your system’s
extensions.
• If you have RAM Doubler installed, insert the
RAM Doubler diskette 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 your 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.
Update the file with a newer version or
remove it from your system.
