A boot-start driver is a driver for a device that must be installed to start the Microsoft Windows operating system. Most boot-start drivers are included 'in-the-box' with Windows, and Windows automatically installs these boot-start drivers during the text-mode setup phase of Windows installation. If a boot-start driver for a device is not included 'in-the-box' with Windows, a user can install an additional vendor-supplied boot-start driver for the device during text-mode setup.

To install a device that is required to start Windows, but whose driver is not included with the operating system, a user must do the following:

  1. Install the device hardware and turn on the computer.

  2. Begin your Windows installation (run the Windows setup program). During the text-mode phase of the installation (at the beginning of the installation), Windows displays a message that indicates that you can press a specific Fn key to install a boot-start driver.

  3. When Windows displays this message, press the specified Fn key to install the boot-start driver and then insert a boot-start driver distribution disk.

Note This procedure demonstrates how you can install a driver that is not included 'in-the-box' with Windows. Do not use this procedure to replace or update a driver that is included with Windows. Instead, wait until Windows starts and use Device Manager to perform an 'update driver' operation on the device.

When Windows fails to start, certain error messages that are displayed can indicate that a boot-start driver is missing. The following table describes several error messages and their possible causes.

Error messagePossible cause

Inaccessible boot device

The boot disk is a third-party mass-storage device that requires a driver that is not included with Windows.

Setup could not determine your machine type

A new HAL driver is required. This error does not occur on most machines, but it might occur on a high-end server.

Setup could not find any hard drives in your computer

The required boot device drivers for the hard drives are not loaded.

Boot-Start Driver Distribution Disk

A boot-start driver distribution disk is a medium, such as a floppy disk or USB flash drive, that contains a TxtSetup.oem file and the related driver files. The TxtSetup.oem file is a text file that contains a list of hardware components, a list of files on the distribution disk that will be copied to the system, and a list of registry keys and values that will be created. A sample TxtSetup.oem file is provided with the Windows Driver Kit (WDK), under the src directory of the WDK. For details about the contents of a TxtSetup.oem file, see TxtSetup.oem File Format.

The following requirements and recommendations apply to platform-specific and cross-platform distributions disks:

  • Platform-specific distribution disks (Windows Server 2003 and earlier)

    Windows requires a platform-specific distribution disk for each platform that a driver supports. A platform-specific distribution disk contains one TxtSetup.oem file and the related driver files. The TxtSetup.oem file must be located in the root directory of the distribution disk.

  • Cross-platform and platform-specific distribution disks (Windows Server 2003 Service Pack 1 (SP1) and later versions)

    Windows supports cross-platform distribution disks that contain two or more platform-specific TxtSetup.oem files and the related driver files.

    To distinguish between platforms on a cross-platform distribution disk, use the platform directories that are listed in the following table.

    PlatformPlatform directoryDefault directory










On a cross-platform distribution disk, Windows uses the platform-specific TxtSetup.oem file that is located in the platform directory that corresponds to the platform on which Windows is running. If a corresponding platform directory that contains a platform-specific TxtSetup.oem file does not exist, Windows uses the TxtSetup.oem file in the default directory, if one is present.

Windows also supports platform-specific distribution disks. A platform-specific distribution disk contains one platform-specific TxtSetup.oem file and the related driver files. The TxtSetup.oem file must be located either in its corresponding platform directory, as is done for cross-platform distribution disks, or in the default directory of the distribution disk.

The driver files for a given platform on a cross-platform distribution disk or on a platform-specific distribution disk must be located relative to the directory that contains the platform-specific TxtSetup.oem file.

Tip Although not required, we recommend that a TxtSetup.oem file always be placed in a corresponding platform directory. Using platform directories eliminates the possibility that Windows might attempt to use a TxtSetup.oem file that is incompatible with the platform on which Windows is running. For example, if a user attempts an unattended installation on a platform with a distribution disk that does not contain a corresponding platform directory, Windows cannot determine whether the TxtSetup.oem file in the default directory is compatible with the platform. If a driver fails to load because the driver is incompatible with the platform, Windows displays an error message and terminates the unattended installation.

This latest version of prime95 has been optimized for Intel's new AVX instruction set. Owners of Sandy Bridge and Ivy Bridge CPUs (Core i3/i5/i7 2xxx and 3xxx) will see a substantial performance boost. Any modern personal computer with Windows, Mac OS X, Linux, or FreeBSD can participate.

How it works:

This page describes what you will need to participate in GIMPS and how it works on your computer. This page is aimed at people with Intel-compatible personal computers, although in many cases it is possible for UNIX and Mac users to participate as well.

In brief, you need:

Prime Time Driver Download

  1. a relatively modern computer - though very old computers can still be useful to help other computers find primes.
  2. your computer on and running more often than off - at least most of the time - it's OK to go on holidays, vacations, etc.
  3. time and patience - testing for a prime can take weeks even on the fastest computers and months on very old computers.
  4. an Internet connection available at least once every two months - more often is preferred, weekly or daily is ideal .

GIMPS requires a modern PC that is on most of the time. The program runs at the lowest possible priority. You should not see any impact on your system's performance. The program will use about 32MB of memory and about 50MB of disk space. WARNING: Running the program continuously will use about 40 watts of additional power, about the same as an energy-saving compact florescent lamp - your electric bill will go up just a little bit.

Most importantly, you will need a lot of patience. Roughly speaking it will take about a month to run a single primality test - visit the benchmark page for a more accurate estimate on your computer.

Setup Instructions for New Users:

Joining GIMPS is usually as simple as downloading and running the program, answering a few questions, and the program does the rest. There are cash awards for discovering a new Mersenne prime!

  1. If you have not done so, CREATE YOUR USERID. It's optional, but required to check your account details, computer status and performance statistics and to assign computers to your user ID.
  2. Download the appropriate free program for your OS
  3. Create a directory and decompress the file you just downloaded. Windows 7, Vista, and XP have built-in unzip features. Other Windows users can choose from a variety of decompression programs. We use 7-zip. Linux and FreeBSD users should use the standard tar and gzip decompression utilities.
  4. Start the program! (Linux and FreeBSD users should run the program from the command line with a -m switch, i.e. './mprime -m'). Enter your optional userID created on the website in Step 1, and optionally name your computer. We recommend Windows users select Options, Start at Bootup or Start at Logon.

That's all you need to do! The program contacts a central server called PrimeNet to get some work to do. Usually the program and PrimeNet know the best work to assign, but it's up to you!

You can administer your account and computers on your userID's account page. Once you complete a workunit you can track your standings on the competitive stats pages the server updates every hour (see Top Producers in the menu, left, for more stats). You can monitor each of your computers' progress, even remote-control the work assignments they request using your userID's CPUs page!

Linux and FreeBSD versions can also be set up to run every time you restart your computer. Ask for help at the Mersenne Forum.

Questions and Problems:

Please consult the readme.txt file for possible answers. You can also search for an answer, or ask for help in the GIMPS forums. Otherwise, you will need to address your question to one of the two people who wrote the program. Networking and server problems should be sent to Scott Kurowski. Such problems include errors contacting the server, problems with assignments or userids, and errors on the server's statistics page. All other problems and questions should be sent to George Woltman, but please consult the forums first.


See GIMPS Terms and Conditions. However, please do send bug reports and suggestions for improvements.

What's New:

  • Windows updated to 30.4.9
    • AVX-512 support.
    • Modified torture test dialog box with new options and better understanding of the L1/L2/L3 cache hierarchy.
    • More robust implementation of Gerbicz error checking in PRP tests. This replace LL testing as the default work type.
  • PRP with proofs. Eliminates the need for lengthy double-checking!!!
  • Resource Limits dialog box to control Prime95's resource usage. See the readme.txt file for setting these options
  • Faster P-1 stage 2.
  • Faster ECM stage 1 and stage 2.
  • Gwnum library overhauled. Many functions deprecated. Replaced by more powerful gwmul3. New functions that compute (a+b)*c and (a-b)*c with less memory accesses. Faster conversion to and from binary.
  • ECM and P-1 can choose the find B2 value for the amount of memory prime95 is allowed to use. For ECM, this happens when the worktodo.txt line sets B2=100*B1 which is the default assignment from the PrimeNet server. For P-1, the best B2 is chosen when the worktodo.txt line specifies the trial factoring depth.
  • For example, 'Pminus1=1,2,20000003,-1,500000,0,70' chooses the best B2 bound for B1=500000 given that M20000003 has been trial factored to 2^70.
