Trying to identify a motherboard i bought.

Specs: Windows XP
I bought a motherboard on eBay about 6 months ago. The person did not know the name of the motherboard neither. He sold as AMD K6 166CPU. The reason i bought this certain motherboard is because it has a cts 206-8 T640.DIP switches. I have a hacker that has overwhelmed two of my computers. What I mean by overwhelmed, these two computers will not start up unless i have my CMOS battery jumper on clear. So i figured, buy something where i can set my own configuration, etc. But for me to use this motherboard and try different options, i need the schematics,& user manual. I canot print one up, because i cannot identify this motherboard. So I am requesting your help. I'll give you as much informtion as possible, here we go - backside of motherboard. M 94V-0, front side from here on out - top right cornner VXATX3 R4, sticker with serial number 70015013. BIOS chipaward Award Software, Inc 1995,PCI/PNP 586 s/n 059579972V______. Has 3 16-bit ISA slots, 3 PCI slots, 1 AGP slot, primary & secondary IDE connector, nothing for floppy. 2 slots for 168 pin DIMM Memory. There are 4 other slots next to the 168 pin slots which i have no clue what there for. Quick discription - 4 1/2" in length, color is white., each one is identified as J5A1, J4A1, J5A2, J4A2.
I do not see a slot for CMOS battery. 1 intel PCIset SB82371SB L6351138 SU093 INTEL 95, 1 PCIset SB82437VX L6304624 SU085 INTEL 95, ! chip named S3 trio64V2/DX P5C3DD 86C775 9647 M4T78-01, 2 chips named SEC korea 646Y KM416C254BJ-5, 2 chips named UMC UM61 3232AF-7 9645S MM9X55, , 1 DALLAS .DS12B887 REAL TIME 9647A2 089450. There is more. I have to go somewhere, but when i get back I''ll try taking a picture. Thank You!,

I guess what you could do is use third party software such as Speccy in order to find out the what make and model of the motherboard is.


Once you've done that go to the manufacturers website and search for the manual.

Tell me the outcome.

Windows msinfo32 should provide some details.

Sorry, but I have to ask - how much computer experience do you have? What are your plans for such an obsolete board? It's too old/slow for anything other than Win95/98 or possibly a low resource Linux distro. If you paid more than $5 for it, you paid too much.

"these two computers will not start up unless i have my CMOS battery jumper on clear"

If you power up a system with the clear CMOS jumper in the "clear" position, you can damage the board. And hackers attack the operating system, not the hardware.

"I do not see a slot for CMOS battery"

That's because they didn't use CMOS "coin" batteries back then, they used real time clock batteries. - Dallas real time clock battery


That would be the Intel 430VX chipset from the mid 90s. It supports a max of 128MB RAM, but only 64MB is cached. The slots you see next to the 168-pin DIMMs are probably 72-pin SIMMs. Beware which type RAM you use. EDO DIMMs & SDRAM are different, SIMMs run at a different voltage & must be installed in matched pairs. And to the best of my recollection, the 430VX does NOT support AGP. If you see a brown slot, it's probably for additional cache (aka COAST), not AGP. COAST = Cache On A STick. The settings for the jumpers or DIP switches are usually printed right on the circuit board. Look at all the following - Intel 430VX specs, COAST in socket, 72-pin SIMM slots, jumper & DIP settings

Here's an old Gigabyte socket 7 board based on the 430VX chipset. Notice the COAST slot next to the CPU socket. Also notice that there are no ports on the rear of the motherboard except for the keyboard (which is AT, not PS/2). Any additional ports (serial, printer, USB, etc) must be connected to the board via cable brackets.

Also, all old boards supported floppy drives so I'm guessing you just missed the connector. One other thing, is your board an ATX or AT? It's probably AT. Make sure the black ground wires are next to each other as shown in the pic - AT power connector

Does it boot up? There should be a bios string usually on the bottom of the posting screen that you can use to ID it.
