Onboard graphics not working after removing PCI graphics card

[milund]

EDIT: I just talked to HP Support. It appears that this Z200 does not have onboard graphics, so removing the PCI graphics card makes the workstation unable to boot.

I have removed a nVidia Quadro 400 PCI graphics card from a HP Z200 Workstation. Afterwards the Z200 stalls at boot with red flashing power LED, six beeps and fans at full speed. There is no signal on the onboard graphics card (I have tried both VGA and DiaplayPort outputs). I have tried to reset the CMOS, but this did not solve the problem. The workstation is able to boot normally if I reinstall the PCI graphics card.

Any help on getting the workstation to run without the PCI graphics card is greatly appreciated.

Hi:

This is the only reason I can think of as to why the onboard graphics may not be working in your particular workstation...

Integrated Intel® HD graphics is supported only on Dual-Core Intel® "Clarkdale" Processors.

it is not supported on the Quad-Core Intel Core i5-700 Desktop Processor Series, Intel Core i7-800 Desktop Processor Series or Intel Xeon Processor 3400 Series

As to why the nVidia Quadro 400 PCI graphics card from another Z200 isn't working, unfortunately I have no idea why that would be.
