you can't just hit fn+f7 or whatever to get the second screen working?

that's what i do.

Can´t be tested at the moment.
The bios chip is already separated from the 7800GTX card.
Will be flashed on wednesday.
I would be happy if anyone could confirm that the bios data has to be written at the beginning of the data area of the ATMEL bios chip...

No one can confirm that for you since we all use nvflash. I was thinking by using a hardware method, you would try the nvflash -j switch by grounding the pin mentioned (supposing you could find a data sheet). I'd imagine the data is written to the beginning of the EEPROM but I can't confirm that in any way.


Also, from the sounds of things your card is dead at the moment, so it won't generate any output, be it to the primary or secondary display.

You are right. Card is dead at the moment.
Just testet another card and this works fine. No boot possibility with the dead flash card.
The hardware programmer flashed card will be back on friday i think.
Then we will see, if the data is on the correct place :-)

Hi guys.
I have just got my externally flashed bios chip back. soldered into the 7800GTX and mounted to the XPS.
What should I say. It works wonderful.
The dead flashed card i back in life and no zombie ;-)
Best Regards...

Hey zzpulp, thanks I have some weird issue going on with my e1705 (GPU = GO 7900gs)

Here's the deal:

I get black screen (still have back light and everything loaded fine (ie, window start up sound, etc..)). Then I tried CD flashing method (which I don't think it worked), but somehow I got the screen back for 1 day, then it went back to black screen again. I reseated vid card many times and still didn't work.

Fast forward to today. I got a hold of usb flash drive and tried it this morning. First try, no reaction. THEN I CLOSE THE LCD LID (LCD turned off when lid was down), then I opened the lid up and VOLA, I see C:\> command prompt on the screen. To my surprised, I turned the lappy off then back on, no picture. Close lid then open, no picture. Then repeat 2-3 times and eventually I get the command prompt on the screen again. Weird eh?

Well anyways, I found out that my autoexec.bat didn't work as it should (now that I can see stuff on the screen now). So, I manually ran nvflash commands for ALL the ROMs that I could use on my card ONE BY ONE, but I can't get any picture when loading from HD (LCD won't turn off when I close the lid if booted from HD). However, I can still use the close lid, open lid method to get the DOS prompt when booting with USB even after all those flashings.

I'm going to try using CRT monitor this evening as well as try to boot from windows XP CD (granted I can see the screen) this evening. What are you thoughts on this?

Holy shit I figured it out!!!!! How to get the damn screen to show image that is (yes I'm typing this on the m1705 right now. WHEEE)

Anyways, here's the fix.

While the lappy is off, connect it to a monitor (VGA output to CRT monitor in my case). Now here's the twist to this fix. Once you press the 'on' button on the laptop, quickly close the LCD screen before it could light up. This will make the CRT monitor to be turned on instead. After I see the DELL letters on the monitor, I almost shat my pants. Anyways, I proceed to open the LCD screen (which automatically turn the monitor off) and VOLA! I everything was the way it was.

If anyone has any explanation for this please feel free to comment.

This issue is not related to corrupted EEPROM. It sounds more like driver problems although obviously its not quite that since you are apparently having the problems within the BIOS. Don't really know what to say but I would be looking into getting a new card if you (even occassionally) cannot get output to the laptop LCD when you boot. This of course implies that you do not have an external monitor hooked up at the time.

Hi ZZ - nice work
Just replaced my broke screen on my XPS Gen2 6800 Go Ultra- lovely job, worked fine for about 4hrs then bam - froze and reboot! Screen then had the blue block terror that I have read about elsewhere so took it apart again cleaned out dust, crap etc and made sure all connections were tight. Rebooted and sometimes got a screen and sometimes not (same on external monitor) then nothing - black screen and backlight with numlock on - no sounds of windows booting. Tried your BIOS flash as per instructions - after about 15 secs get 2 beeps, numlock flicks off and then comes on again and responds to keyboard but screen remains black with backlight - any ideas??
Any help welcome

While this issue seems to be related to your video card, it is not cause for blind flashing as far as I know. You did not break the card by flashing it so blind flashing it back to stock or whatever would do you no good. I'd suggest maybe trying to get a replacement video card from Dell.

Hello,zzpulp!
...so far I see,your method seems to me that working...!...
but what if I have ATI card?
My gpu is ATi Mobility Radeon 9600/9700,with id 4e50(M10/M11),vendor id1002...,on notebook Clevo TurboX D870!
So,what I did:
I want just to modify the clocks of gpu & memory(to decrease)-by the bios was 486MHz/520MHz DDR,and I extract the bios file with AtiFlash program,I just decrease the clocks(nothing else),I save the bin file modified,and I flash the vbios with the same program!
My mistake,of corse,was that I flashed from windows...!....so,start flashing,after give me a messege that can't erase rom,I click "ok" then "erasing rom"...I wait 2 hours,but nothing happened...still this message "erasing rom"...!
...I restart my PC,and...Black screen!
Now,I've tried "blind flash"with "flashrom" and "atiflash"programs...!
I create USB bootdisk,I create CD bootdisk with another flash file found on only "techpowerup.com"site-the flash file is not original,is not for mobile,but the clocks are allmost the same(because the original bios file is on the 2HDD's of the notebook,are configured in RAID mode,so I can't explore them to take the original flash file),...I create autoexec.bat file with the commands required by the flash programs,I insert the command" -f" to force flashing...but nothing happened...-I think that I did anything possible...!
Now,the pc ,I think, boot from USB flash drive,because when I power on the pc the LED start flashing few times then stay ON few minutes,then the LED goes OFF and nothing happened!
PLEASE,if you have any suggestion I'll appreciate a lot!
Thanks in advance!

Before I answer this I think its important to mention that I have never owned an ATI card or even interacted low-level with one heavily.

Anyway...

I don't think using a desktop rom will work even if it has the same clocks. The roms are most likely completely different except for the clocks and parts of the identifier string. So, I think you need to find the proper rom for your card first and foremost. Anyway, you can always make sure the flash drive is booting properly by putting the line "dir > out.txt" into an autoexec.bat. This line will pipe the output of the command to a file and will let you know that the flash drive was booted to.

I put in the command line of autoexec.bat the command that you say,but nothing change-the same!!!
I will tell you exctly how is behave the pc now:
I insert the usb flash drive,I press start button,the CapsLock,NumLock and the ScrLock light once,the coolers strts,cd-rom led flush 2 times,then the led of the usb flash drive flashing 7times then stay on!After 1-2minutes when the usb led goes off,doesn't do any command-not even Ctrl-Alt-Del !!!When starts,no beep sounds,no any other lights-NOTHING.
All this I did even removing the HDD's,the Bios battery,wireless module,bluetooth module,cd-rom,pc battery--anything that can interfere with boot process.The dos programs I use for flash are "flashrom"and"atiflash".
Finally, I found the flash file for Mobile,but the same!
I forgot to mention that the usb boot disk is working on all the others pc's,with all the commands that I insert!
I realy don't now what's happened!....

Its really a bad sign if you cannot get the dir command to pipe the contents of the flash to a file. This means that your GPU is inhibiting the boot process. There's really nothing you can do software-wise to fix this issue. In fact, this is the issue that keeps most people from recovering their card. Even if you were able to get around this, there are other restraints such as the flash program potentially no longer recognizing your card.

So,now, do you think if I replace the vrom programmed with original flash file,it will come alive my gpu and anything will become normal?
Theoretically I think yes...!

If you are talking about programming the card hardware-wise then yes you have a chance. But the whole boot + flash process is most likely gonna get you nowhere. Once you get a funcitioning GPU back in your machine (either by buying a new one or fixing this one), it should work normally.

Hardware options:
Somehow get a new EEPROM on there without wrecking the card
Reprogram the chip: There are a number of ways and Nvidia even supports doing it via nvflash plus grounding a pin on the card. Problem is no one knows exactly where that pin so you'd have to try other reprogrammers. I know you have an ATI but I figured I'd tell that NVIDIA story anyway.

First of all...why do you think you need to blind flash your card?

Hi ZZPULP,

i got upgraded my acer 5520 from a 8400m G to a 8600m GT.
When i put the 8600m GT into my laptop nothing happens. Only the powerlight is on and somtimes te proc. light flashes. when i put a bootable usb stick with the bios and nvflash into the lappy the usb stick`s light flashed sometime then nothing happens, again... :S Only my CAPS LOCK ligt goes on... Do i something wrong or is my card just dead?

Apparently, when buying MXM cards, you may have to flash your own machine's video card BIOS to it before you're able to use it.

In your case, I would make an autoexec like so:

dir > out.txt
nvflash -4 -5 -6 -A -y [romname].rom >out2.txt

However, I really can't recommend doing this as it MAY kill the card. I would make sure you have the latest system BIOS on your computer first. Supposedly, the system will ask you to reflash the MXM card when it detects the 8600M.

Note: the system bios and video card bios are two separate things.

Oh yeah, and also, you can't use nvflash v 5.xx since its too old for your card. Just use the other link I have to get the latest nvflash. In this case, you would have to press 'y' to confirm the video card flash after you think its ready.
