Due to monitor limitations, you may want to disable detection of your display adapter during an unattended install.
To use the default VGA driver, modify your answer file:
\[Unattend\] OemPreinstall = Yes \[Display\] InstallDriver = 1 ConfigureAtLogon = 0 BitsPerPel = 4 XResolution = 640 YResolution = 480 VRefresh = 60 AutoConfirm = 1 \[DisplayDrivers\] "Standard VGA (640x480, 16 colors)" = "RETAIL" To find the text string to use in the \[DisplayDrivers\] sections, search for VGA in the Txtsetup.sif file:
forcevga = "Standard VGA (640x480, 16 colors)",files.none
On the above example, RETAIL indicates that the driver is on the Windows NT CD-ROM, while OEM means that it is provided by a third party manufacturer.
