hi all. I somehow flashed the wrong bios because now It won't turn on. all lights are on and nothing happens.. =(

any solutions? I have the bios backup in a bootable pen but how to do it?

thanks,

That's a pretty old board. I don't think they had the BIOS protections the newer boards have today. Once the BIOS is corrupted, it is unrepairable by the user. The BIOS chip would have to be physically replaced, I believe. You might contact ASUS for some support to be sure, though.

Hi there.
First try to reset you bios. This will hopefully set it back to normal settings. You can do this by using the jumper on your mainboard ( near the battery ) or just remove the Cmos battery and put the battery in up side down while the powercable is disconnected and pressing the power button for a couple of times.

I can remember that there is a bios protection on this mainboard but you can force a other bios to be flashed with the force command. Dont know how you flashed your bios.

yeah I tried asus crash bios utility (alt + f2 ) before post but the problem is it won't post to the point that detects the keyboard.. once I turn on the card fan is 100%, the error code is CPU INIT and it does nothing. all llittle lights from the maximus series is turned on.

maybe you can tell me if this is the bios from my motherboard, o took this picture. http://img824.imageshack.us/img824/8328/img201301240111...

Hi there Marciu.
I will check your picture tonight at home. Imageshack is blocked at work lol XD.

Hi there.

Back at home. First off all here you can find the English manual of this mainboard.

Can you remember which bios version you used?

To clear your bios settings to factory settings you can hit the Clear CMOS switch. Check if you want this website. Scroll a bit down and you will see a overview of the mainboard. Check point number 11.. thats the big boy you can use for clearing your bios, putting it on original settings.

If that doesnt help we need to search a bit further. Let me know if it helps ;)

Cant edit my previous post so here you go




Red = Bios chip
Green = under the battery is your CMOS reset switch
Blue = Bios Battery

I'd be curious as to if that works or not. As far as I can see, that will only set the BIOS back to default. You will still have the wrong BIOS. But maybe you'll get lucky...

yeah That location is the bios. I don't know how I missed that little spot sorry.

but no method work to flash this dead bios because it won't even post. no messages no nothing. tried with crash bios utility method in manual too but nothing.

I'm waiting for the new bios chip to arrive and then I must prepare to replace it!

thanks!

Let us know how the solder job went when you're finished. Not a task for the untrained.
January 24, 2013 8:18:38 PM

I know it's a expert task but I'm kind of skilled with this stuff.

I have a old motherboard and just experimented dissolder and solder a 8x2pin chip.
to solder is very easy even with my crap iron but the problem is to dissolder, since you need to apply some force in the chip to come off at the same time you apply heat. I'm confident lol and in a week or 2 I will post update

Good idea practicing on an old board. De-soldering was what I was especially referring to. Here's some pointers if you need a refresher. But you sound like you have it well under control...

here's what I did on the 3 chips in order. (de-solder and solder) http://imageshack.us/photo/my-images/210/sam0483m.jpg/

thanks! the more information I get before it's more likely I will succeed. I may buy a better iron solder and those basic tools

The left row of pins of #1 and #3 look like they are shorted. #2 looks pristine. Or am I not seeing it correctly?
Do you have a Radio Shack in the UK?

Had good reviews, although I've never used one.
January 24, 2013 9:16:03 PM

That looks like shorted because of the flux I did not clean :p 
I live in portugal but I will give a try without the de-solder tool. If it's hard I will stop to not damage the contacts.

lucky me... they sent a wrong bios http://imageshack.us/a/img18/4250/wrongbios.jpg GRrrrrRRr

I sent an email for another bios site and they said these bios models are compatible " MX25L1606, or Winbond W25X16AVSSIG, W25Q16BVSSIG, CFEON F16 and sst 25vf016b any one would suit you. " but all of them are the correct size.

one question now... Is there any harm If I try that bigger bios in my smaller bios spot? (with some wires ) because supposedly the bios they sent is programmed for my motherboard.

Wow! I don't know if I can answer that. I've done a lot with PCs, but never physically replaced a BIOS chip. Since the PC is all but dead now, I would probably go for it. I presume you mean remove the existing chip and temporary wire in the new chip. But my question would be, how would you know for sure that the 4 solder pins on each side of the new chip match up with the solder pins on the old chip the way you have it positioned in the pic? Did the rep verify that would be the case?
January 28, 2013 7:11:22 PM

well the bigger bios has that little thing that aims down, like the smaller one. I don't know If I should send from another site. The ones that sent me the wrong one didn't reply yet but I'm here without doing nothing... lol

I did this wiring just now in older motherboard. the spot is smaller to the asus motherboard http://img5.imageshack.us/img5/9918/wiringh.jpg
January 28, 2013 7:18:00 PM

oh god thank god they sent me an email saying they'll send the new bios without any cost.

I have to compliment you on your soldering. Very good. The smaller the points I have to solder, the shakier I get. :??:

thanks for the compliment lol
I received the right bios today =D hopefully my friend will help me as soon as possible to safely remove it. and then I can try to recover the old one and solder it
January 31, 2013 9:07:09 PM

well I just removed my bios with the help of that little tool. and with the technique that you add a little solder to all 4 pins make contact to each other making possible to remove both at once. I was shaking A LOT http://img203.imageshack.us/img203/7602/step1wf.jpg

now I will clean the best I can and proceed to put the new bios without soldering to recover my old one. Nervous!!!

Looks good so far. Btw, you must have removed the FP pinout insulator block next to your work area. Those tall pins look like they are missing something. ;)

yes I remove that plastic in the bottom and bend them to have a little more space hehe

now I need something like this http://www.hipro-tech.com/images/hipro5/1_ASUS_P5E3_WS_...
and a solder sucker because the contacts aren't flat enough to place the bios straight

Is the new BIOS chip the correct size this time, instead of an over-sized one?
February 1, 2013 12:15:17 AM

well I did it! I couldn't wait again... and everything works fine!! at least in boot, no errors.

Bad luck me or lucky me... I managed to recover my old bios but now the new bios it's broken I think. lol
at fist it did work but then I think I just shorted(I shorted both several times lol) and was giving the "no nvram found"

next tried to recover the new one but it said " bad file block size" or whatever when writing the file into flash.
mehhh I soldered the old bios and now must put the cooler the right way to test in windows.

here are 3 photos. enjoy xD

How did the new chip short? The old chip too? How did you get the old BIOS chip re-programmed? I'm not exactly following you...
February 1, 2013 2:14:47 AM

By short I mean when I was hot flashing (pressing the bios with the pen) the bios moved and some contacts were off. very hard to hold the bios while typing.
I did not re programmed. hot flashing means you turn on your computer with one bios (the one I bought in this case) and then just before you flash with afudos a new rom you switch the bios and then it flashes the rom into the old or bad bios.

I'm happy! now I don't need to buy a cpu+motherboard =D only my graphic card that from time to time needs to cook in the oven lol

February 1, 2013 2:32:00 AM

yep! =) replying in it right now. never ever ever I will flash another bios. xD
I have the latest anyway.

Great adventure I had lol

Congrats. If you have time, post the steps you took from the time the old BIOS chip was still on the board. I might find myself in the same predicament some day.

Btw, I flash BIOS's all the time on the PC's I build. Can't have one going out with an old BIOS version. But one has to be sure one is getting the correct version for the MB it is going to be used on. You just had bad luck choosing the BIOS for your board. Apparently got the wrong one. I only get BIOS's from the board's manufacturer.
February 1, 2013 12:04:33 PM

As soon as possible I will do step by step. including the soldering?

I would flash too if I get any updates on my bios now but unfortunately I renamed the wrong bios file to the "right" one. it happens : P

OK. You don't have to post the steps. It's just that I apparently had a wrong notion of what it was you were going to do with the new BIOS chip. I assumed you were going to "wire" it temporarily to the solder points where the old chip was to see if it worked. But that was when you still had the incorrect replacement. I think I got confused after you said you received a replacement to the replacement.

Bottom line: you did good and your system is up. :) 
February 2, 2013 11:36:59 AM

yeah basically instead when I recieved the new one and solder it right away I tried to recover my old one (with hot flash). the wiring thing was to try that big bios they send me wrong but I did nothing to it.
my english it's not the best for all this technical things hehe

thanks for support =D
