3. Check that all other adapters are firmly seated in their sockets.
Replace the cover and try the power again.
4. If it still does not boot, remove the TurboChip from your computer
and replace it with the original Pentium processor. Try the power
again. If the computer now starts, the processor upgrade may be
incompatible with your computer.
Support for help in diagnosing any problems.
Cannot Access Diskette or Hard Disk Drive
You may have dislodged the connection between the diskette or the hard disk
drive and its controller card when you installed the processor upgrade. Check
this connection now.
Older System BIOS
Some early model 75MHz and 90MHz Pentium systems do not support the
faster CPU technology. In some cases, the computers have older system BIOS
which must be upgraded to support the TurboChip 233 MMX
processor. The older incompatible BIOS may cause the system to lockup or not
boot up at all.
This problem can sometimes be resolved by upgrading the BIOS version of
your computer, either with a software update or by replacing the chips. First
check with your computer manufacturer or visit their website for a software
utility to update your existing BIOS. If your system does not support flash
ROM software updates, the next option is to replace the BIOS chips.
BIOS chipsets are relatively inexpensive and can be purchased at your local
computer store, or contact Unicore Software, Inc. at 1-800-800-BIOS (2467)
to order a BIOS upgrade. Unicore supports all the major brands of BIOS
chipsets, including AMI, Award, Phoenix, MR BIOS, and others. Unicore
