VGA1 : 15-pin D-Sub Connector
NOTE：
When system boots up without the MONITOR attached during the POST, the
VBIOS will disable the MONITOR output. Under this condition, the MONITOR
display will not work and the system will need to be rebooted with the
MONITOR attached to enable the display. The problem originates from the
VBIOS of the IntelR Extreme Graphics Driver, which disables the MONITOR
output if a MONITOR is not detected during POST.
