<title>Configuring the BIOS DMI Information</title>
<body>
<p>The DMI data that <ph conkeyref="vbox-conkeyref-phrases/product-name"/> provides to guests can be changed for a
specific VM. Use the following commands to configure the DMI BIOS information. In case your VM is configured to
use EFI firmware you need to replace <codeph>pcbios</codeph> by <codeph>efi</codeph> in the keys. </p>
<ul>
<li>
<p>DMI BIOS information (type 0) </p>

$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/pcbios/0/Config/DmiProcVersion" "Pentium(R) III"</pre>
</li>
<li>
<p>DMI OEM strings (type 11) </p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/pcbios/0/Config/DmiOEMVBoxVer" "vboxVer_1.2.3"
$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/pcbios/0/Config/DmiOEMVBoxRev" "vboxRev_12345"</pre>
</li>
</ul>
<p>If a DMI string is not set, the default value of <ph conkeyref="vbox-conkeyref-phrases/product-name"/> is used.
To set an empty string use <codeph>"<EMPTY>"</codeph>. </p>
<p>Note that in the above list, all quoted parameters (DmiBIOSVendor, DmiBIOSVersion but not DmiBIOSReleaseMajor)
are expected to be strings. If such a string is a valid number, the parameter is treated as number and the VM will
most probably refuse to start with an <codeph>VERR_CFGM_NOT_STRING</codeph> error. In that case, use
<codeph>"string:<varname>value</varname>"</codeph>. For example: </p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/pcbios/0/Config/DmiSystemSerial" "string:1234"</pre>
<p>Changing this information can be necessary to provide the DMI information of the host to the guest to prevent
Windows from asking for a new product key. On Linux hosts, the DMI BIOS information can be obtained with the
following command: </p>
<pre xml:space="preserve">$ dmidecode -t0</pre>
<p>The DMI system information can be obtained as follows: </p>
<pre xml:space="preserve">$ dmidecode -t1</pre>
