The Pentium® OverDrive® processor was designed to be a user friendly
upgrade minimizing hassles and worries surrounding a processor upgrade. This checklist
was compiled to help troubleshoot some of the common issues that can come up.
- Did you check the online upgrade guide?
If your system is not listed, you may want to contact your system manufacturer.
- Did your original processor work fine with your system before you put
in the OverDrive processor?
Make sure your system is healthy before upgrading with the OverDrive®
processor. If you don't, you may make existing problems worse.
- Did you make any jumper changes or voltage changes?
If your original processor was an Intel® Pentium® processor and you
are upgrading to a 120 MHz or higher Pentium OverDrive processor,
no changes should be made unless listed in the Online Upgrade guide.
If your original processor was an Intel486™ processor, check
- Do you have the latest BIOS for your computer?

perform the update with your ORIGINAL processor. Damaging the BIOS
update can cause damage to your system so if you're uncomfortable, please take your
system to a computer center who may charge a nominal fee to perform the
BIOS update for you.
- Can your system run in Windows* 95/98 safe mode with the OverDrive

works fine in safe mode, most likely that means you need to update some
drivers. In this case, do a Windows step-by-step boot up to note the
point of failure and get the driver for that device from the
- Have you added hardware before upgrading with the OverDrive
Strip out the added hardware and see what happens. Then gradually add
the components back in. Sometimes, the added pieces of hardware are not designed
to work with the faster OverDrive processor (or the hardware may work if
you obtain a driver update).
- Did you take out the extra memory or cache?
Memory should be metal-matching with the connector. Take memory out of
system and see what happens. Once again, some memory components were not designed
to run at the OverDrive processor's higher speed.
In addition, SIMM trees or SIMM expanders definitely shouldn't be
