Compaq dc7800: DC7800 CPu id and BIOS update probem

Hello

My first post here, I hope you get what I'm trying to say.

Well, I have this old compaq dc7800 sff and I managed to level it's OS to Windows 10.

And now, I would like to update its bios and CPU id, but I can't run those exe, I downloaded on the cd7800 support site.

I know that these bios update programs and so forth are not published for Windows 10, but I thought that windows7 versions would work.

But they did not.

For some reason, I got the the messege that "software publisher has refused to run this program on this computer.

While this mean?

I can't run these programs even with administrator privileges, I get the same messages?

Because of Windows 10? Or what?

The reason why I came across this problem was that I tried to update the CPU of the Q6600 to Q9550 and I got the error of CPU - ID firmware.

Hello:

It is very easy to update the BIOS on a dc7800 without being under Windows.

In the menu of the BIOS on the file tab, there is a rom flash system command.

All you have to do is put the BIOS files on a USB stick formatted with the FAT32 file system.

Rather than go though all the steps to get the BIOS files, I've zipped or less than joint under attachments.

Unzip them and copy the content of the file of the folder (not the folder), for your USB flash drive.

Plug the flash drive into your PC and restart it, tap the F10 key to access the bios, select the file menu and on this list will be a rom flash system command.

What to choose, and the PC will 'see' the files on the flash drive.  Follow the instructions on the screen to Flash the BIOS.

I have attached files to the latest revision of the BIOS (1.32 Rev. A (6 Dec 2011)).

If you still get the microcode error after updated the BIOS with the latest version, let me know, because then update the firmware, and it is a much more complex process.

  • CPU and BIOS update problem

    I have a M57P 6395 33 M system and some time ago I added an E8500 CPU, I thought it would work even if Lenovo not listed the E8200, E8400. I was a little disappointed and I still wonder WHY lenovo gets SO specific with CPU connection. I don't see why she accepts only 2 CPUs and no other?

    Well, I bit the bullet and found an E8400 to put in the machine. I added CPU, removed the MB battery and left out for a while then went back on the new shoe, set all the necessary info. The first part of the BIOS screen mentions that there lies an E8400 (as he did for the E8500) but when it goes through the boot process it is said AGAIN that the CPU code is not enough to recognize the E8400. I am now confused.

    When I updated the BIOS, I used the that I've been led to believe was the GOOD .54KT23AUS (through the windows), but I still get the error 0167. It would be better for me to put the back E8200, re run the BIOS update using a CD?

    and there is another update of BIOS listed for the M57P 2RKT64A, I wonder if it would be better? It is not for use on 6395 but, the FIRST thing listed for THIS update is an update of firmware of CPU.

    I know that this means not much to all the world and I hear people say 'why bother? ' but I would use the machine as I'm n ot offer a more recent machine as I am a pensioner.

    A little help please.

    Thanks a lot for the quick response. I tried Flash via the CD with the E8400 in and it would not allow me to do when he came up with the error of CPU to half way through. I have since updated the E8200 back and did the BIOS update through the CD. The machine seems to have taken the update of the better BIOS this time but, the E8400 still does not work

    As for the E8400 CPU, I have an Intel CPU program on the computer and deepening classified by it for the E8400 says it's A07? However, I can't find any info on it. I guess I either will set up with hitting the F2 key when I start with the E8400 inside or just keep the E8200.

    I finnd the info on these rather confusing processors. The Intel CPU app I have gives me different information from a site like CPU world. The TDP of the processors are 65W but the ONLY thing I see different is the deepening of the base. The E8200 is listed as C0, while the E8400/8500 are E0. Why who would have much effect on the use of the more major? You would have thought that Lenovo engineers could make the system accepts the E0 revision or what is Lenovo wants to sell a new machine?

    Like I said, it's a shame that Lenovo is so affected by these machines with tunnel vision. Well

  • Equium M40x-189 and BIOS update

    There are updates of bios for my laptop, and so I thought I would try a flash update. I can only find the Trad version and not the flash version of Win.
    the problem is that the traditional flash update file asks you to create a bootable cd for the update procedure. Software CD, Toshiba in their wisdom have provided a cutting of the version of "save now". Guess what this special version of toshiba cannot create a bootable cd you have to spend £25 for the full version.
    Someone knows, there is a version of the flash upgrade Win

    Hello Andy

    As far as I know just BIOS updates listed on the download from Toshiba site are available. I guess that your unit is a relatively new. If you have any problems with this device do not do any BIOS update. Only if there is a problem the update of the BIOS by using external devices or something like that is recommended.

  • Satellite L40 PSL48L: No noise and Bios Update after installing XP

    Hai guys

    I have a toshiba laptop psl48l-0200u and lowered the score on XP Professional, but realtek audio does not work.
    At the launch of the facility, there is an error message "realtek audio installation failed.

    I think that this may have to do something with bios - then I downloaded Bios for XP and extracted into a folder - but the update of the bios.

    Help, please
    Thank you

    What to first say if you installed XP on your laptop, then you should also update the BIOS to the version of Win XP.
    The BIOS update must be performed on Windows XP!
    Simply run the exe file and follow the instructions on the screen.

    Regarding the sound issue.
    Well this problem is not related to the BIOS, but you have not installed the XP patches!

    Have you checked this forum for a similar question? I don t think so.

  • XPS 15 9550 CPU speed is as low as 0.75 ghz after manually installed windows 10 with all the drivers installed and BIOS updated

    I just bought this XPS 15 9550 in January, and I really appreciate it at first.

    However, one day, as pushed microsoft update to 10586 version of windows 10 and the machine will always fail to install the update, so I decided to download the image file and install it myself.

    The installation went smooth, but after a few days use, I found the computer is very slow during playback of videos and games and I came to find the speed of the CPU shows the label of performance in the Task Manager always will be 0.75 ghz and 0.78 ghz. He cannot go above that. I also found that the use of the CPU cannot exceed 30%.

    I've already updated my BIOS to 1.1.19, reinstall the system, a few times, choose the battery mode high performance, etc and this does not help.

    I also downloaded the power of intel and found gadget for my processor power consumers are still weak and the speed of the CPU is always not 0.80 ghz.

    In addition, I encountered the problem that after plugin the AC power, the speed of the CPU will fall to 0.39 ghz...

    Someone at - it an idea of what is happening here and how can I solve the problem? I'll really appreciate it. Thank you.

    I had my problem is solved. Follow these steps:

    1. download gadget power intel, you can search online for it.

    2. check the power of your CPU (package pw...) rate and open the videos and applications that will constantly consume the CPU power. See if the power is still weak.

    3. If the power is still weak, try to update your BIOS (download dell drivers and the new version should currently be 1.1.20) and see if things are getting better.

    4. If the power is still low, you must contact dell technical service to replace your hardware (my computer has replaced the northbridge, southbridge, I forgot, but after replacing, the CPU works fine)

    Note: If you run games using your discreet graphics card, such as starcraft II and you found that it's extremely slow, it is possible that your cpu is capped.

  • Tecra 8100 - CPU max, DVD - ROM and BIOS update issues

    1. I have a 500 MHz processor on my 8100. I would like to upgrade to maximum capacity. I think it's 800 MHz since it is the highest, the series went to.
    But if it's 800 MHz, any Mobile PIII on this frequency do? Or should I check for special settings of the processor?

    2. I don't have a floppy, or ways to get drive one. And I'm not going to ebay one just for an update of the BIOS. Any ideas? A bootable CD with the files will do?

    3. What is the location of the DVD-ROM and what alternative models can I use? The 8200 went up to 8 x DVD - RW. Could I go further?

    Thank you. I hope that my post is OK like this instead of three different positions.

    1 take a look at the other Tecra 8100 models to determine which processors are compatible.

    2. I don't think that would work a bootable CD, you must follow a special procedure to update the BIOS and requires a floppy drive. If there is a version of Windows, you must use that instead.

    3 upgrade the DVD player can be difficult because you must use the correct master/slave settings, and it must have the same design of the façade of the original.

    Personally, I'm selling the laptop and buy a second hand faster one. It can work out to be cheaper.

  • Update satellite A200 - 14F CPU T7400/T7600 and BIOS update

    Hello

    I want to upgrade my current Core Duo T2450 CPU to something faster or T7400, T7600.

    I know that PM945 will manage it but what about the BIOS? I have 1.80 which is the last for my model.

    Where can I find that some BIOS change log to see if the newer processors are supported?

    Are you sure that you want to upgrade the processor?
    An upgrade of the CPU will not bring much more performance but mobile CPU's are fairly expensive and maybe they are not supported in the BIOS or motherboard.

    Moreover, Toshiba doesn't support a CPU Exchange. You can do this, but at your own risk.

    Normally a BIOS change log you can find on the driver of Toshiba download page, but if you can find t we Web does not exist on the site.
    But I'm pretty sure that Toshiba doesn't add new taken processors supported by a new BIOS because it s not supported.

  • Satellite A210 - heating and BIOS update problem

    My aunt was having problems with his A210, so she bought herself a new and gave me the old one. The problems that she has been seen was the computer kept stopping at random. I think it's an overheating problem because the laptop runs quite hot. The BIOS has never been updated so I thought that might help with this problem. in any case, when I tried to update the BIOS this error message came.

    > Has anyone else experienced problems with the A210 of overheating? All solutions?
    Hi mate

    I m a Satellite A210 owner and to be honest, a higher internal temperature might occur if the laptop would not get enough air to cool the internal parts like CPU and GPU.
    A few weeks ago, I used the laptop on the sofa I don't the opinion of t that the cooling that are placed at the bottom of the unit fans were clogged because of my position relax, if you know what I mean ;)

    After a short period of use, the laptop shut down automatically I was a little surprised, but I realized that air could not circulate, and so the laptop overheated

    Now, I m using the unit only on the desktop. This method is recommended, and it helps to keep the temperature at the lower level

    PS: My BIOS is updated...

    Toshiba support would anyone tell me if and when we can expect Windows 8 x 64 drivers for Toshiba T210? The equipment is fairly standard. I'm sure it's very easy to compile the drivers available in the official version

    I also wanted to know like when Toshiba T210 finally gets the update of the BIOS. Its current version of BIOS is 1.60 while many other models similar and earlier jumped to version 2.2 of BIOS and above

    Kind regards

    It is user forum so that you will not receive response from Toshiba support directly.
    What I can say is followed by:
    All about Win8 on Toshiba laptops, you can read on http://www.toshiba.eu/innovation/generic/windows8-message/
    Under the terms of the Toshiba compatibility matrix, you can check if your phone model is supported for Win8 or not.

    What about BIOS. Toshiba doesn't offer updated BIOS if there is not a critical issue or a reason for it. If your piece of hardware working well and stable there is no reason to update BIOS. What do you expect should happen with the latest version of the BIOS?
