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.
