    hi,

    I messed up with the bios of my 9800m gts and did something that screwed up my laptop.

    I pretty knowledgeable about crisis bios flashing casue I am a hardware/software modder, but I am serious trouble this time.

    basically what I am trying to do is to reflash the bios of my 7805u with the crisis bios recovery utility.
    I found many around and have tried the most different combinations of files ect.

    I know how to activate the bios recovery procedure on the 7805u by holding FN + ESC and power on, the pc reads the floppy just fine and I hear beeps as usual when the pc is about to flash the bios in crisis mode. once the pc read the bios file in the floppy it stops and for about 5 minutes keeps sending out random beeps, but no flash is being performed at all.

    I power down the system after 20 minutes that has been on flashing and nothing I keep getting the same error code. 1 long been and two short ones. Which in the bios beep codes list shows up as “bad video” or “video error”.

    I thought the most various and different scenarios.

    1) the system bios is fine, in this case all my attempts to flashing the system did not success, therefore the bios is still intact. So basically I shouldn’t mess with the system bios.
    2) The problem could be the video bios (I am almost pretty certain about this), therefore the system powers on but it does not allow me to see anything. I cannot even blind flash because the keyboard does not accept input whatsoever and basically because the system does not boot at all. The only thing that recognizes is the crisis recovery mode (thank God for now).

    for the second case I bought this device here: http://www.hwtools.net/Adapter/PE4H.html

    which is coming in today where I work. I’ve been expecting it for a week now.

    My theory is that, by plugging in PCIE video card in it, the system might bootup and allow me to reflash the primary video card. This is the only reason I bought this device for. Basically out of desperation. ( I do not intend to send out the laptop to gateway unless I’ve tried them all, and honestly in the past I went through worse with modding hardware/software and this looks to me totally doable.

    In the past I’ve had this same issue with desktop systems where I screw up the video card’ bios and am left with two options depending on the severity of the situation:

    If it’s not two bad usually I can just blind flash the card by just putting in a bootable floppy diskette or cd and typing in the strings in the command prompt even though I cant’s see a thing. After that the recovery is 100% good.

    If it was a more serious problem (like in this same exact case), the system does not even boot to windows/dos and does not accept keyboard input, therefore I need a secondary PCI/AGP/PCIE video card to put in the desktop then, everything works fine. I am suddenly able to enter dos and reflash the primary cad like normal.

    In my actual case with the laptop, the fact that I cannot access a secondary video card cuts down almost all my possibilities, because I cannot type in anything. The system will not boot at all. The laptop powers on, gives the beep error code message then it just sits there.

    The reason I bought this: http://www.hwtools.net/Adapter/PE4H.html
    Is to maybe being able to simulate the same scenario I’ve had before in a desktop system.

    But something tells me that maybe it’s the system bios that is screwed up. So I have been trying to reflash with no success.

    My in success though comes from only one factor. That the bios for the p-7805u/7811fx is 2MB in size and obviously 2MB will never fit into a floppy disk, no matter how much you empty the floppy disk.

    So I tried creating USB pen drives/ USB flash drives, but nothing it doesn’t really work this way.

    So I found on the net a version of Crisis Bios Recovery that allows you to compress the bios down to 1.2MB, this way I am able to put in the flash recovery tools in the floppy disk as well and this is why so far the floppy disk seems a very reliable way to proceed.

    I think though that maybe the whole compression of the bios is sort of screwing it up, casue after the floppy has finished reading the bios it just gives random beeps for 5 minutes but no flash is being performed.

    I tried doing something, I put in a bios from another laptop that was only 1024MB and after reading the file, the fans on the CPU started going like crazy, indicating that a bios flash was being performed. Although I think that the flash must have been interrupted at some point because the fans kept going on for more than 10 minutes. So I powered down the system and then back to the same error code.

    So then I tried creating a bootable CD with the same image for the floppy (but with the compressed bios for the 7805u) and it worked. The Crisis Recovery mode was able to read the CD and did the same procedure. The only problem is that again, the bios in the CD was the compressed one.

    So I looked around on google and found a applications like UltraIso and MagicISO and many others, that allow me to edit the 144MB.img file where the boot sector for the floppy is stored.

    If I burn the 144MB.img or 144MB.iso into a cd I am able to boot up in crisis bios recovery mode.

    But whenever I edit the boot sector image file ( to insert the non compressed version of the bios which is 2MB) it screws it up and the cd does not boot in crisis recovery mode.

    Can somebody out there PLEASE HELP me create an image file, *.iso *.img *.ima or whatever format I can burn into a cd therefore being able to reflash the bios in my system?

    I hope I’ve given enough information although in a very scattered way. I apologize.

    I found a way to drastically lower the temps of the 9800m gts by volt mod, but I was eager and wanted more, therefore I screwed up.

    The last successful flash of the video bios allowed me to have temps no higher than 58 degrees celcius under full load in assassin’s creed for more than an hour. But again as I said I srewed up cause I wanted more.

    I will post the files for anyone to try out (the good ones) to successfully flash the video card and lower the temps, but I first need to resuscitate mine. Please help.

    Thank you

    Try PM to johnksss. He dug himself out of hole with the 7811 BIOS. I think it was in this thread but there were so many threads in the beginning. It is easier to try PM.

    Are you sure it's the Bios and not the CMOS? Try resetting your CMOS first. LYK how you make out if you are sucessful.

    That would be your first step. Both have the same type of symptom's. If it is your bios, Check out MyDigitalLife forums. Their tool thred tells you how to make a bootable USB flash. They also have a "modded" bios for the 7811/7805u with a CRCDiskRecovery setup included. Http://forums.mydigitallife.info/showthred.php?p=107145

    If you can't find it I have the downloaded bios and instructions how to flash. Check it out, it may be of help. LMK how you make out.

    But, first I would try the CMOS before anything else.LOL!

    I'll try that. thanks

    though, the link doesn't work.

    I received the PE4H adapter to connect an external PCIE video card to a laptop, and rushed home on my lunch break to try it out. no succes on this one. :(

    maybe I need to create one of those USB bootalbe drivers for the PCIE card to be seen during POST, but at this point I doubt it has anything to do with this. it has to be the BIOS. I hope I can flash it with the modded bios you were talking about.

    thanks for your help

    Great-from what I understand it is a dos bootable flash drive with all the files. Has a set of instructions that you have to following when flashing. Hope this works as I hate to see someone "brick" his notebook . LMK hoew you make out.

    thanks! I feel the same way. it was for a good cause even if I started to get greedy about it.

    I'll post my results on voltmodding the 9800m gts once this nightmare is over.

    I'm home now. I will try out the procedure on that link.

    If the video bios is voltmodded he needs to flash, cmos is not an issue. That is the problem with hard modding the video bios, once you trash you have to flash...........

    I know, that's what I am trying to do but I can't find a way to do it.

    all the bioses that I am finding around or the ones already posted in these threads they are all not compatible with my 7805u fx board.

    even if a bios flash would be successful, I would still not be able to see anithing on screen.

    I checked with phoenix bios editor pro 2.2.0.1 all of these bioses and they all contain either intel VGA or nvidia 8800 GTS. but I need one with the 9800m GTS in it. unless the system bios and the video bios are handled separately. which could be an option. the fact that I was able to flash the video bios with nvflash somewhat proves it. In my other HP laptop when I want to modify the video bios I first have to unpack the system bios (rom image) with phoenix bios editor then I look on the temp folder for the option.rom file that belongs to the onboard VGA, then I modify the VGA rom with nibitor then at this point the process is backwards. I re-insert the modified VGA bios into the system bios, buid the image then flash. any other way than this one will result into bricking the laptop. but of course crisis bios recovery always allowed me to resucitate the dead laptop.

    not in this case, because the BIOS for all 78xx models is 2048/2057 MB. which sucks casue it does not fit into a floppy disk. if I'd have a2.88MB floppy disk drivve I'd be able to create the image file by extracting it from the floppy and burn it into a bootable CD. I think this is the only way it would work.

    unless the BIOS has 1MB of crap in it that would have to be sorted out with a hex editor and that would be nearly to impossible to figure out.

    why does the BIOS for the 78xx models have 2MB file size? is really all occupied? and why I am not albe to open it with phoenix bios editor? anyone can help?

    thanks

    You can open it with PBE. Just have to get the newer one 2.2.0.13 at DigitialLife web site. It's 2 MB because it has a .wph & a .rom file plus the flasher. The USB flash drive didn't work I take it.

    Have you read thru the forum as it does have a wealth of information about recovery from a bad flash? I'll take some time this afternoon and see if there might be solution to your problem.

    Those Bios 9C.17.00 are for the 7805u/7811 series laptops. LYK if I find anything else.

    I downloaded PBE 2.2.13 and by opening the 9c.17.00 I saw the 9800m GTS rom file which means that only a successful flash will allow me to resucitate the laptop.

    do you know of a way to extract the ROM and WPH files from these 2MB rom images?

    also do you know where I can find the bios in this thread? http://forum.notebookreview.com/showthread.php?t=312573
    it ha been removed. it belonged to a packard bell ipower GX basically the same model as the 78xx versions but with quad core support. the reason I am looking for this file is because maybe it's only 1MB instead of 2MB.

    thank you for you help

    I may be wrong as I have never had to do a Bios Crisis Recovery myself. You said you were able to start-up with a CD ? If that's true, then you can make a Bios Crisis recovery bootable CD disk. Then you are not limited to size.

    Also, I don't think you need to include both the WPH AND ROM files on the floopy. From what I read, you just replace the generic bios.whp (contained in the CRCdisk) file with either the rom or wph and flash with that? One file would only be around 1MB plus the flasher and batch file, which is still under 1.44 MB.

    On the site I told you about that file they pointed you to was for a floppy. (For a 7805u bios flash) It was over 2 1/2 MB total, but only because they included both rom and wph file. I think they mention it is best to use a wph for CRC, and rom if you don't have one.

    Am I wrong in thinking this???:confused: :confused:
