In Windows, you can see information about the motherboard installed in your PC using various GUI tools. In Linux, there are no such tools installed out of the box. While you can install some of them to get motherboard information, there is a single console command you can issue and get your motherboard model and other details instantly.
Usage is pretty straightforward and you simply choose your drive from the drop down box, enter the new serial number and click the Change button. Do note the serial number format as mentioned in the window is made up of 8 hex characters from 0-9 and A-F split by a “-” into two groups of 4. You will then need to reboot to commit the changes. Serial Change Steps: Remove the R W screw from the motherboard; After it boots into developer mode, press CTR+ALT+F2 the key, this should open a terminal; In the terminal type 'chronos' Then 'sudo su' Then 'vpd -l' On the displayed list you are looking for 'serialnumber' To change the entry do the following. Select Advanced, System IDs, and enter the serial number from the service tag sticker on the chassis. Press F10 to save settings and exit BIOS. For desktop branding, customers need to fill the following details availble on the HP sticker of the unit.
There is a special console tool dmidecode which utilizes sysfs to provide information about your motherboard. Here is a brief description of the tool taken from its man page.
dmidecode is a tool for dumping a computer's DMI (some say SMBIOS) table contents in a human-readable format. This table contains a description of the system's hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision. Thanks to this table, you can retrieve this information without having to probe for the actual hardware.
While this is a good point in terms of report speed and safeness, this also makes the presented information possibly unreliable. The DMI table doesn't only describe what the system is currently made of, it also can report the possible evolutions (such as the fastest supported CPU or the maximal amount of memory supported).
SMBIOS stands for System Management BIOS, while DMI stands for Desktop Management Interface. Both standards are tightly related and developed by the DMTF (Desktop Management Task Force).
As you run it, dmidecode will try to locate the DMI table. It will first try to read the DMI table from sysfs, and next try reading directly from memory if sysfs access failed. If dmidecode succeeds in locating a valid DMI table, it will then parse this table and display a list of records like this one:
Handle 0x0002, DMI type 2, 8 bytes.
Base Board Information Manufacturer: Intel
Product Name: C440GX+
Version: 727281-001
Serial Number: INCY92700942
Each record has:
A handle. This is a unique identifier, which allows records to reference each other. For example, processor records usually reference cache memory records using their handles.
A type. The SMBIOS specification defines different types of elements a computer can be made of. In this example, the type is 2, which means that the record contains 'Base Board Information'.
A size. Each record has a 4-byte header (2 for the handle, 1 for the type, 1 for the size), the rest is used by the record data. This value doesn't take text strings into account (these are placed at the end of the record), so the actual length of the record may be (and is often) greater than the displayed value.
Decoded values. The information presented of course depends on the type of record. Here, we learn about the board's manufacturer, model, version and serial number.
To find the motherboard model in Linux, do the following.
- Open a root terminal.
- Type the following command to get the brief information about your motherboard:
The output will be like this:
- To get more details about your motherboard information, type or copy-paste the following command as root:
See the following screenshot:
The -t argument filters the output by the specified DMI type. 2 means 'Baseboard'.
When you are using the 'baseboard' option for the -t argument, it uses a combination of DMI types (as SMBIOS specification defines), so you see more details.
Type man dmidecode to learn more about its command line argument.
That's it.

Some multiplayer games that implement the PunkBuster anti cheat system get cheaters off the server using hardware bans. It used to ban the hard disk serial number but no longer does that since there are ways to spoof and temporarily change the so-called hardcoded serial number. So now they’ve started to ban the CD-Key. Other than that, some licensing system also uses the hard disk serial number to generate a unique hardware ID which is then used to generate an external license file to activate the software.
A simple way to find your current hard disk volume serial number is to open a command prompt (Win key+R and type cmd) and then type dir. The second line shows your volume serial number for the system C partition. Type dir [driveletter:] and it will show a different serial number even if the volume is on the same physical hard drive. The volume serial number changes every time you format the partition and Windows also uses this value during activation so you can’t simply move your install from one partition to another. If your Windows has been activated using a product key from a sticker it will probably ask for the key again after a reboot and will need reactivating if you change the volume serial number on the system drive.
If you do a simple search in Google, you’ll find tons of information about to change your hard disk volume serial number, but not the real hard disk serial number that is hard coded into the hardware. Some people said that it is impossible to change it, but we will show you that there are ways to change both volume and hard coded serial numbers for your hard disk.
1. Hard Disk Serial Number ChangerThere are a few free tools around capable of changing the volume serial number and one of them is called Hard Disk Serial Number Changer. The name is a bit misleading though as it doesn’t actually change the hard disk serial number but the volume serial number which is different. It works on just about any Windows operating system from 98 onward and is a standalone portable executable but does need to be run as administrator on Vista and 7.
Usage is pretty straightforward and you simply choose your drive from the drop down box, enter the new serial number and click the Change button. Do note the serial number format as mentioned in the window is made up of 8 hex characters from 0-9 and A-F split by a “-” into two groups of 4. You will then need to reboot to commit the changes.

2. VolumeID
Another useful tool to change the volume serial number is by Sysinternals called VolumeID. This tool is only usable from the command line so won’t be as quick and easy to use for some people as Hard Disk Serial Number Changer. The command line usage to change the ID of a drive volume/partition is:
volumeid [driveletter:] xxxx-xxxx
The format is again 4 hex characters, a “-” followed by another 4 hex characters. You should shut down all your running applications before using this tool and will need to reboot immediately after the changes if they are being made on an NTFS partition.
Download Sysinternals VolumeID
The tools above are fine for changing the serial number of a volume/partition but trying to change the serial number of the actual hard drive itself is a whole different story. These are hard coded into the hard drive itself and cannot simply be edited or altered using a piece of software. There are however, several tools around that can spoof the hard drive’s built in serial number temporarily which can hopefully fool whatever software you are trying to get round. Unfortunately a lot of these tools aren’t free and some are even approaching $100 to buy.
3. PB DownForce
There is a free tool that’s been around for quite a while called PB DownForce which is able to temporarily spoof your hard drive’s static serial number into a different random or seeded number. There is also an option to set your own predefined serial number although we were unable to get that function to work during testing. To use the program in it’s simplest form, all you have to do is start it up and click on the Start spoofing button. Make sure to run PB DownForce as administrator.
The Advanced options button shows the 3 different types of spoofing to choose, although as mentioned we couldn’t get method 3 to work as intended and it just showed a serial full of a single number. You can easily use the Stop Spoofing button and try another random number. Perform test will quickly tell what drive model name and serial has been given. The image below shows a new serial after using PB DownForce to change a hard disk serial number in the PC Wizard hardware information tool. Do note that some tools such as Speccy will still show the original serial number for the drive because they gather their data in another way, HWInfo does something different again and will show the spoofed drive as another completely new hard drive in its list.
PB DownForce was tested and worked on Windows XP and Windows 7 32-bit although it still was quite random to which machines worked and which showed no change or produced an error. 64-bit Windows is not supported in any free hard drive spoofing tools we came across. The spoofed serial will return to normal after a reboot.

Reboot as in restart. As far as I’m aware, reboot your computer has never implied resetting or reinstalling it.
ReplyAbout PB Downforce,
Well the Windows Service I grabbed turned out to be a .sys file, obfuscated by VMProtect(1.X).
It’s internal name, as Windows Explorer tells me, is: ‘helper.sys’. So, this means it’s a Windows Device Driver, a .sys file.
But that’s food for IDA Pro, when I’ve got the time.. :)
Regarding PB Downforce,
The executable drops a service into your %TEMP% folder, which it uses. It’s the temporary folder from Windows.
What I did was, preventing the removal of contents in my %TEMP% folder. Very interesting, now I’ve got the service DLL to tinker around with.. Let’s see if that contains a virus. :)
Windows Defender quickly picked the DLL up as ‘ Trojan:Win32/Tiggre!rfn ‘.. Could be bad..
Windows Defender is well known for false positives. In fact, it’s one of the worst there is.
However, tools like this will generate detections in AV software, it’s unavoidable.
ReplyConcerning PB Downforce, I got interested.
Windows operating systems based x64-bit, have KPP (Kernel Patch Protection). So the hooks on DeviceIoControl, which PB Downforce applies, are rendered useless.
If you’re on a 32-bit system, then there’s no problem for you.
Some notable strings in the PB Downforce executable are as follows, after unpacking:
IOCTL_STORAGE_QUERY_PROPERTY
SMART_GET_VERSION
SMART_RCV_DRIVE_DATA
IOCTL_NDIS_QUERY_GLOBAL_STATS
IOCTL_STORAGE_QUERY_PROPERTY
IoBuildDeviceIoControlRequest()
DeviceIoControl()
PhysicalDrive
ServiceName
PBDOWNFORCE_SERVICE
The executable file itself was packed with ASProtect, and was made with Microsoft Visual C++, with its wxWidgets.
The good news is, it does not contain a trojan.
TROJAN included at your service
ReplyOf course there isn’t, try to have a bit of common sense. Antivirus and security software obviously hates programs like these because they are essentially hacking tools.
ReplyTried installing it it kept showing me an error dialog box Error:communication failed.
I dont know what next to do.

ReplyAbout PB DownForce.
It is mentioned that It will spoof your hard drive’s serial number but temporarly. So you’ll need to spoof your hard drive’s serial every time you open the game and connect to that certain server you’re banned in order not to get tracked?
Hello,
PB Down Force just made my day…..Thanks a lot….You are awesome.
ReplyI’m trying to use PBdownforce on win 7 64 but I’m getting error: “communiction failed”. Any help on this ? Any other tool to spoof hdd serial on win 7 64 ?
ReplyAs stated in the article PBDownforce doesn’t work on 64-bit Windows, we couldn’t find any free tools that do.

ReplyIt’s written clearly on the download page.
ReplyAnother utility which allows changing of a volume serial number is “MiniTool Partition Wizard”, what’s more it changes the whole 32 bit long serial number, not only the last 16 visible bits (8 characters).
ReplyWindows Motherboard Serial Number
Sorry, my mistake – MiniTool reports Volume ID as a 8 byte (16 characters/64 bit) value, while other programs report only 4 bytes (8 characters/32 bits). Don’t know what is the leading 32 bits, but the last 32 bits is the same as reported by VOL utility.
Replyhello! PB downforce is very useful for me but can you please tell me how to use my own serials and macs? I mean… what is the standard format? because I fill the fields with original and new serial and it doesnt work. Thank you very much!
ReplyThank you very much for the info, I need to change my hardware id….
