20 Most Recent Tyan Tiger MPX S2466N-4M Motherboard Questions & Answers

This is very difficult to troubleshoot because there are too many unknowns.
Does the mobo have diagnostic LEDs? The changes in indicators would indicate the boot up activity is taking place. If you have no visual indicators, then
You might have to get a boot up code display. This is a device that connects to the bus (via pci / pcie slot in most cases) and has a digital readout. When the mobo stops on a certain code, you will have to lookup the code to determine where it's getting stuck.
If you have no access to a diagnostic card, then some of the other very "elementary" things you can do are:
Listen for the beep code. If the speaker doesn't beep at all, then your CPU is likely not running the POST test. Check your power on LED. Check your HDD LED to see if any disk activity (hdd detection) takes place.
Other than that, you're SOL without some equipment.
Good luck!

Hello sir, hi, as I see it, your problem, can be anywhere in the PC, but I do suggest you test first these 5 parts on a separate PC, by swapping. Here are the possible 5 faults:

1. Memory, even though is passes the counting on the bios, does the counting completes? i mean if your PC memory is 256 MB, it should count up to 256 MB.
2. Processors, just make sure both are fine.
3. VGA graphics card.
4. Power supply box.
5. Motherboard itself. To check this part, make sure all parts on the top 4 are good.

If all are considered tested and good. you may need to check other parts. So check for:

• connections,
• loose seating of video cards,
• shorted or bad faulty DVD/hard disk drive,
• plugged in USB devices, just remove them all.
• reversed IDE cable, (the old one can be installed reversed)

The troubleshooting of your PC really takes time, But i do consider the motherboard to be the faulty one. Thats why we need to test everything before we consider the motherboard be the culprit.

probably the board is bad or the board is grounded out on the chassis edge somewhere or possibly the mounting screws...

recommendation.. pull the system out of the chassis


test the power and board on a sheet of cardboard...

also try one stick of memory only and set the options for full ecc scrubbing on to test the memory correctly

There is a conflict in shadow ram. Check the add-on cards. It may be necessary to disable the BIOS shadow into RAM in order to make space for the other cards ROM

This error is "Initial Superio_Early_Init switch" This error occurs when The first memory module is bad or the BIOS is corrupt. Exchange RAM. If that does not work, Reset the BIOS by removing the battery for two minutes If that does not work, replace BIOS; or motherboard.

contact Tyan and request support, just say that the hardware was in a machine you were given. It might be that that there is a generic password built int the firmware. Such a practice is common on most electronic equipment, hope you are lucky. Otherwise look for an answer on Tyan forums or Tom's Hardware

Is this a bios error code onthe onbaord diagnostics? As this is a server board be careful - reset the bios to defaults is the first step in solving motherboard issues. Remove all cards and begin testing - remove all ram chips except one and test replacing stepwise until you have isolated the issue - usually the bios error code is the last item to pass before failure. Looks like it could be DMA controller failure but you would need the manual for the board to be sure.

look at board near front panel on the sides

It is a bridge initilization error according to the manual. I would try removing the memory and just use 1 module and see what happens. If that doesn't work, try pulling other components, including the video card to see if you can isolate the problem.

Hi Can you tell me the brand and model of the mainboard and I'll get you what you need, those details read on the mainboard, the brand is often between the expansion card slots, Asus, Abit, Gigabit, and similar, it can also be between the cpu and the memory. The model is around the same area, if you are not sure, post me everything you find. thanks
