Unknown Jumper Settings

I have a P54C motherboard and I'm trying to install a 233 MHZ CPU (was a 133).  I don't have the manual and don't know which jumpers to change.  The jumpers I do see are 3.3, 3.4 & 3.5 which I assume are voltages. My board name:
03/04/96 W83787F PnP-S; ID#: 03/04/96-i430FX-2A59CPDC-00.
Please let me know if I need a CPU with the Overdrive voltage regulator and which jumpers to change.  Thank you

I haven't the foggiest.  If you know of any type of software that can tell me that, let me know.  The info I gave you already came from SiSoft's Sandra.  I'm not sure I trust it though since it says I have "American Megatrends" bios yet when I boot, "Award" is posted on the screen.

Take a look at the picture of the "Gemlight GMB-P54SPV"
motherboard at:
http://www.gemlight.com.hk/PROindex/G_P54SPV.HTM

and see if it matches your motherboard.

Note that 'P54C' is a model-number for Intel's "Pentium" line of computers.

Direct this to Otta:  No, my motherboard is all Intel chipsets except for the bios which is Award.

Direct this to Skylab:  I'm ready for those utilities when you are.  Again my email address is:  bmcgraw@home.com

Thank you both

I attached a system report generated by SiSoft's Sandra.  Has they been reviewed yet?   It stated that the motherboard is a P54C 75-233 3.3v.

Post your BIOS string that apears at bootup.  This might be helpful in IDing your motherboard

Just thought I'd mention that manufacturer PD is unknown. Try CTBIOS and see what it spits out.

Skylab, I am interested in this utilities too ............please send them to me - second@softhome.net

gigaman, if your board is P54C it does not support the dual-voltage required for P55C (Pentium MMX, 6x86L, 6x86MX, MII, K6, K6-2), so you can not install this CPU (233) on your board. Your options are:
1) Buy a WinChip 180 or 200 with will run perfect on your board (it is 3.3Volt or 3.52Volt - you have sayed that you have a 3.3/3.4/3.5 setting - the WinChip will run fine there)
2) If your board support 75MHz bus (200MHz CPU - 66bus, 180CPU - 60bus) you can buy a WinChip 225
3) If your board support 4x multiplier (133MHz CPU - 2x, 200CPU - 3x) you can buy a WinChip 240
4) You can buy a K6-2 overdrive - it will run on your board 100% - for 266/300/333 MHz K6-2 overdrives check this url: www.cpu-central.com/k6-2upgrade.html
don't buy a Pentium MMX overdrive - it run at only 200MHz and don't have the 3DNow! technology of K6-2

Skylab:  Did you happen to run across the manual yet?  And you mentioned two utilities.  What was the other one besides CTBIOS?   (Just checking.)

That PowerLeap looks like it might do the trick but this motherboard isn't listed in their compatibility list.  

Thanks again

One processor (not motherboard) which Intel manufactures
is named 'P45C'.

Well aint this a peach.
I just recieved a fax from "Azza" after enquiring about your question. They faxed a manual!
I don't think it's right though.
The manual is for an ABL432GSX, a total 486 board!
The fax is pretty unlegible too.

I'm not any closer to getting ahold of a manual but the suggestions about where and what to upgrade to will be helpful.

Thanks
