<title>Configuring the Hard Disk Vendor Product Data (VPD)</title>
<body>
<p><ph conkeyref="vbox-conkeyref-phrases/product-name"/> reports vendor product data for its virtual hard disks
which consist of hard disk serial number, firmware revision and model number. These can be changed using the
following commands: </p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/SerialNumber" "serial"
$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/FirmwareRevision" "firmware"
$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/ModelNumber" "model"</pre>
<p>The serial number is a 20 byte alphanumeric string, the firmware revision an 8 byte alphanumeric string and the
model number a 40 byte alphanumeric string. Instead of Port0, referring to the first port, specify the
required SATA hard disk port. </p>
<p>The above commands apply to virtual machines with an AHCI (SATA) controller. The commands for virtual machines
with an IDE controller are: </p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/piix3ide/0/Config/PrimaryMaster/SerialNumber" "serial"
$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/piix3ide/0/Config/PrimaryMaster/FirmwareRevision" "firmware"
$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/piix3ide/0/Config/PrimaryMaster/ModelNumber" "model"</pre>
<p>For hard disks, you can mark the drive as having a nonrotational medium by using the following command: </p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/NonRotational" "1"</pre>
<p>Additional three parameters are needed for CD/DVD drives to report the vendor product data: </p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/ATAPIVendorId" "vendor"
VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/ATAPIProductId" "product"
VBoxManage setextradata <varname>VM-name</varname> \
"VBoxInternal/Devices/ahci/0/Config/Port0/ATAPIRevision" "revision"</pre>
<p>The vendor id is an 8 byte alphanumeric string, the product id an 16 byte alphanumeric string and the revision a
4 byte alphanumeric string. Instead of Port0, referring to the first port, specify the required SATA hard
disk port. </p>
