Pentium cpu voltage issue
I've got the 200MHz MMX cpu now, and after changing the jumpers to dual
voltage, I was surprised to find that the machine reported att bootup it was a Pentium(MMX) running at 200MHz. Some websites with info on this motherboard have suggested you need a BIOS upgrade to support the MMX cpu:s, but since it recognises the cpu, I don't suppose this is necessary? rcm711 wrote: I have the same motherboard. Mine is MB-8500TVX-A ver 2.3. Checking you posted documents, the second page list the P55C (code name for the Intel 166/200/233 MMX) under 2.9 v settings. The Intel MMX were supposed to run at 2.8 v. I did a google search and came up with this page. It is the same as yours. Your motherboard and mine appears to be a Biostar. http://www.bioteq.com/support/manuals/mantvx.htm Based on this page, it should support an MMX cpu at 2.9 vs.. However, for proper recognition of the CPU, you may need a bios upgrade. This can be difficult to do. So your board may or may not officially support the Intel MMX cpu. I read a post that said the BIOS upgrade support 2.3 or later boards. I am pretty sure you can run the 200 MMX CPU. Check if the motherboard when it starts says it is a 200 MMX Intel. If not in the BIOS it will recognize it as a non-MMX or Cyrix or AMD. |

Older BIOS recognized the CPU by the jumper setting and supply the correct
voltage and motherboard BIOS support based on that. Since it reported it correctly, it works and is supported by that BIOS. Don't BIOS upgrade as it may kill the motherboard if you do it. Only do it if you need something that the newer BIOS offers. I have about an 80-90% success rate in flashing BIOSes on older systems. As far as I know, I followed the instructions right but the systems died. I am happy you got the board up and running as you wanted. "Anton Gustafsson" wrote in message ...
