Precision 3620 no video
Since I messed with BIOS in my Precision 3620 (service tag removed), video is gone. (So I can't even access the BIOS anymore.)
This PC has an NVIDIA Quadro M2000 graphics card, but neither that card nor the onboard HDMI or DP ports work.
I have tried to reset BIOS as described in post Precision 3620 RTCRST, to no avail.
I would be glad to at least re-activate Non-active display ports.

Thank you @Chino de Oro and @mazzinia_.
I eventually got it back.
Indeed. The problem is that BIOS firmware reset (to BIOS Default or to Factory Settings) does not reinstate the Legacy ROMS !
One needs to use another graphics card to have the Legacy ROMS back.
(Otherwise you can try to do it blind : F2, Down x3, Tab, Space, Tab x2, Enter x many)

Hello, besides reset BIOS, replace the CMOS coin cell battery with a new CR2032 instead of putting the old one back.
You can not use non-active port for display due to the lack of integrate video in Xeon CPU. Just make sure that you are connecting the monitor to the Quadro M2000.

@Chino de Oro I have tried this:
Computer restarts several times then ... no DELL logo.
(Tried several monitors & cables).
My mistake was to disable "Enable Legacy Operation ROMs".
Would it work if I inserted another type of video card?

Those taken steps were to clear CMOS and reset BIOS to default settings. Computer was restarted several times, an indication that the BIOS firmware was reset.
If you already tested with different monitors and cables, then yes, you can test with another video card.
While the monitor was without Dell logo, did it show the message of no signals? What LED color was on the computer power button?
Post was edited to clean up for clearer information.

Hello,
there are 2 kinds of cpu that fit on that motherboard ( and is valid for xeons too ) : one with onboard graphic , and one without.
Remove the Quadro card, and check if there's an onboard gpu ( in that case you are lucky ).
If you are unlucky, do you have any newer gpu to install to reach the bios screenshot ? By disabling the Legacy Roms , if by any chance that quadro had a firmware variant with only legacy support....

@mazzinia_
Had no luck. My CPU provides no video.
I have an NVidia Quadro P1000 which hopefully does not require those Legacy ROMs.
