Sun Microsystems VIRTUALBOX VERSION 3.1.0_BETA2 - Manual (Page 64)

4 Guest Additions
4.3.3 Unattended Installation
In order to allow for completely unattended guest installations, you can specify a
command line parameter to the install launcher:
VBoxWindowsAdditions.exe /S
This automatically installs the right files and drivers for the corresponding platform
(32- or 64-bit).
Note: Because of the drivers are not yet WHQL certified, you still might get
some driver installation popups, depending on the Windows guest version.
For more options regarding unattended guest installations, consult the command
line help by using the command:
VBoxWindowsAdditions.exe /?
4.3.4 Manual file extraction
If you would like to install the files and drivers manually, you can extract the files from
the Windows Guest Additions setup by typing:
VBoxWindowsAdditions.exe /extract
To explicitly extract the Windows Guest Additions for another platform than
the current running one (e.g. 64-bit files on a 32-bit system), you have to ex-
ecute the appropriate platform installer (VBoxWindowsAdditions-x86.exe or
VBoxWindowsAdditions-amd64.exe
) with the /extract parameter.
4.3.5 Windows Vista networking
Earlier versions of VirtualBox provided a virtual AMD PCNet Ethernet card to guests by
default. Since Microsoft no longer ships a driver for that card with Windows (starting
with Windows Vista), if you select Windows Vista or newer as the guest operating
system for a virtual machine, VirtualBox will instead present a virtual Intel network
controller to the guest (see chapter
6.1 , Virtual networking hardware , page 88 ).
However, if for any reason you have a 32-bit Windows Vista VM that is configured
to use an AMD PCNet card, you will have no networking in the guest initially.
As a convenience, VirtualBox ships with a 32-bit driver for the AMD PCNet card,
which comes with the Windows Guest Additions. If you install these in a 32-bit Vista
guest, the driver will automatically be installed as well. If, for some reason, you
would like to install the driver manually, you can extract the required files from the
