HELP! HELP! 9800M GT bios on 8800M GTX=black screen

Help me please.
I have a 8800M GTX device ID 060C 1558 and I flashed a 9800M GT bios with all the ID's changed to mine..
Flash Ok, restart and then black screen.

I've tried a blind reflash with r:nvflash oldbios but it makes two very short beeps.
I've tried this with all modified bioses in my cd but same.
I've tried r:nvflash -4 -5 -6 -a -y oldbios.rom but it makes one long and two shorts beeps (not the very short ones)..
HELP ME

 

using r:nvflash -r -5 -6 -j oldbios.rom produces one very short beep.
r is how my drive was recognized.
Anyone can do a (safe for you) 8800M GTX bios flash to tell me what do these beeps mean?

 

It's not a good idea to do a different BIOS flash right?Glad that things work for you now.

 

Did you push Y every 5 seconds until you hear that friendly beep saying the flash is complete?

 

nothing is good now..i don't know what to do.
I'll try pushing every 5 seconds..but have you ever experienced this?

 

I'm not saying it's stupid, but even if you did manage to change the bios and overclock, would you get more than a 5% boost anyway?

 

the boost was of 10-13%.. Can anyone do nvflash -r -5 -6 -j oldbios.rom ??it is safe with the same bios!

 

When I had to blind flash, I used nvflash -4 -5 -6 oldbios.rom, hit y every 5 seconds or so for about a minute, and restarted. Didn't have any problem after that. I'm not sure what the -r -a -j commands do though.

Its a gross feeling you've got isn't it... your card not working and all...

 

thanks emike..but with what card you used it?i'll try

 

That was with my 8800M GTX. I flashed it inside FreeDOS and it wasn't too happy about that. Fixed it in the standard Win ME DOS environment. Had to remove my HDD because BIOS got reset too and couldn't boot through to USB.

 

After doing what you said..now I have one long and two shorts beeps also at startup. This is the same sound of when the vga is not inserted!
I don't understand what freedos means..I use the boot98SC.IMA file to make the disc bootable.
The CD is the first boot option in my bios and it doesn't seem to be changed

 

Try using the Win ME environment. zFactor has links to the HP boot utility.

FreeDOS was a free DOS alternative, and it sucks.

 

and how do i know wich drive letter is assigned?

 

the default of the HP boot utility is C:

An advantage I have with my PNY Attache is that it flashes when its being read from, so I know when its booted. then i just type nvflash -4 -5 -6 oldbios.rom and hit y and its good!

 

less than 0.1% boost.

@oile, if you can't fix it, you just voided you warranty and looking to pay $500 for a new card.

 

emike I don't understand.. you booted from USB or CD??
I boot from CD and I escluded USB from the boot list, so what I have to do??

 

WORKED!! After a lot of temptatives doing the same thing, it worked!!
r:nvflash -4 -5 -6 oldbios.rom worked.

Thanks emike for your help and thanks Nirvana for your moral kick!

I don't know how.. the only thing that changed is that I leaved it off for hours and then It worked

 

Ya what you did is risky changing around teh bios for the cards.

 

But now that you've figured out blind flashing, you can feel a lot more comfortable screwing around with your BIOS! I sure did. Glad you experimented and fulfilled your curiosity.

 

Good thing it didnt just brick your vga cmos.

 

But the super strange thing is that firstly it doen't sound out anything, then one long and two shorts beeps only when inserting commands, then the same sound but at startup, and after few hours it worked with same environment and istructions..
I am scared of flash the OC'ed one now!!

 

Just make sure you flash it with add modded version of your backup rom and you'll be ok.

 

Yes, I always do this but how do you explain this situation??

 

By booting from the CD, you add another layer of potential errors. Because in blind mode, if the CD fails to read, you'll get error messages, and if you push the keys enough, the keyboard buffer overfills and then beeps in response to inputs.
A bootable USB stick is pretty bulletproof on startup, as long as it is primary in the bios boot sequence.
Congrats on the recovery... sometimes these second chances feel reaaalll goood!
A bootable PCExpressCard is another option, that eliminates the need for a extra device; the CD or USB Stick...

 

Ok, I accept the possibility of errors reading the cd, but I use the same CD-RW every time I flash bios since six months and I've never had errors.. now all the errors at once?
and then magically with same cd non rewritten all errors disappear???

 

maybe you should try to flash 9800M GT bios with USB this time?

 

If you want to try the reflash, I suggest getting the USB Stick or PCExpressCard SSD to work while only reflashing the default current bios. Once you prove to yourself that it works, then move on to experimenting... Keep record of you steps in case you have any futher issues.

 

Why would you want to flash the 8800 bios with the 9800 bios? Its not going to change anything at all. There will be no difference in performance in the slightest as all your doing is renaming the card.

 

cuz that's being helpful. lol.

 

what is the point in flashing the 9800 bios into the 8800? they are both the exact same cards.

 

Maybe he's going to sell it.. hahaha

 

well if he thought there would have been a performance increase, there would not have been any. the only thing i can think of is forcing compatibility issues related to bios corruption even if flashed the right way.

 

I don't understand..

 

Maybe he just wanted a new bios version...

I just tried it without changing the card id, it gave me mxm structure errors, and if I change the id, it gives a black screen as oile described. Luckily my usb stick blind flashed fine first time

 

well, why u flash 9800M gt bios on 8800M card??

sry, but this very st****.

i got this problem on my old x1800 card.

wasn't able to reflash. i needed a new card, hope u have more luck.

 

why is it stupid? The 9800M GT IS a rebadged 8800M GTX, so all it is is a bios update. It was an eperiment.

 

the 9800m gt is the exact same card as the 8800m gtx. it is just rebranded and called 9800m gt. phyiscally they are identicle and identicle performance so trying to flash the bios of the 9800 into the 8800 is just asking for trouble.

you were looking for performance gains by flashing, right? well, there would not have been any performance gains even if your flash was successful. the only thing you would have done with a successful reflash was introduce bios-related errors.

 

Maybe, or maybe the bios was written well enough to merit renaming a 8800 gtx to 9800 gt.... Not likely I admit, BUT it would have been a great posting if it actually improves a 8800 GTX performance. I for one support the pioneer spirit in people. That AND the brass balls to try...

 

doesn't 9800M actually got few extra features compare to 8800M?

 

i have exacly the same problem how do you do it ollie~!

 

i think the screen is turnd off! :O help

 

nvflash -4 -5 -6 it work after a few times :d

 

You have to have an updated system bios!! anything from 1.00.09 is good because 1.00.08 doesn't recognize 9800M GT !
Then I succesfully flashed 9800M GT bios on 8800M GTX however! leaving 060B of course..

 

I don't see why you guys are even risking this, when there's nothing to gain.
