What if my motherboard doesn't support the 6x86?
(back to Frequently Asked Questions) (back to Cyrix/IBM 6x86 FAQs) What if my motherboard doesn't support the 6x86?
First off, unless your board doesn't support dual-voltage (assuming you are using a 6x86L, early 6x86's don't use dual-voltage), your problem is in the BIOS. Even if your BIOS doesn't recognize your 6x86 as a 6x86, it should still work. The best thing to do is receive a BIOS update from the board manufacturer, this will most likely add official support for the 6x86.
If it turns out your board isn't capable of dual-voltage (also called split-rail voltage), you still may be able to use the 6x86. The best advice is to get an original 6x86 chip. It is highly un-recommended that you run a 6x86L on a single-voltage setting (if it works at all).
It may also be possible to run a non-L version 6x86 in a Socket 5 board. Since Socket 7 and Socket 5 are identical, except for one unused pin, it is possible for the 6x86 to plug into a Socket 5 socket. This is not recommended, of course.
