I have a brand-new build with a Tyan Thunder n3600M s2932 - (PN #S2932G2NR-E). For CPUs I have two AMD 2384 (quad core 2.7Ghz). I have 1 stick of 4GB ECC Reg 800Mhz DRAM per CPU.

I've tried all combinations of ram and cpus and cannot get the thing to POST. The LED indicator on the mobo starts as FF then goes to D0 and then the thing hangs.... Fans work, drives spin up, but no video, and no beeps.

Using a brand new Antec Quattro 1000W PSU.

If I boot without any CPU or memory it just flashes "FF"...so I know it is recognizing the CPU at some level. If I boot with a CPU and no memory I get the same "FF D0" hang...

Any suggestions? Must be either the mobo, the type of memory, or a bad PSU. I have no cards hooked up...nothing. Tried attaching a USB keyboard and mouse...nothing. Tried attaching a SATA drive...nothing.

I can't check or upgrade the BIOS, because I get no video and no boot! Grasping at straws here...

You need to have at least BIOS version 2.03 to recoginze the shanghai processors.

Can you get your hands on some older barcelona processors to see if it can boot?

If you can't, check with Tyan to see if there is a ROM chip that you can get (I know some tyan products have replaceable ROMs.)

If you are sure it has at least 2.03 then I don't know what to say.

Thanks for the quick answer. I'll get my hands on a barcelona and try that. I wish there was a way to tell what version of the BIOS it shipped with...a sticker or anything!

For the record, there is a way to tell what BIOS is on a new motherboard. You need to remove the top sticker (which in my case says AMIBIOS etc.etc.) and underneath it was another (previously hidden) sticker with the version of the BIOS. Indeed, mine was shipping with 2.0.2 which does not recognize the Shanghai processors. Rather than hunt down a Barcelona, I've ordered a new one from BIOSMAN -- an outfit that was recommended by Tyan.

such things are just why I prefer a socketed bios chip then you are always on the safe side, all the gamer boards have a problem, their bios chips are soldered , it would be hard to replace these after the waranty heh and I had a very bad experience in that sector and now using 2P setups for my Vid to HD DivX converting to real time flight simulations everything goes alot better faster and much more stable.

Anyways use a PLCC Bios extractor tool to remove the bios chip. these things can evade damage to the chip it's self, just an advice there, I have met lads that used a screw driver and their results weren't so bright.
