Over the past few months, I've been intrigued with the idea of attaching a VGA monitor to the HP EX470. Every time I take my server apart (whether it be at upgrade the RAM to 2GB or upgrade the processor) I can't help but to notice the empty connectors on the motherboard; the most interesting of those are silk screened CN2 and CN10. I just knew that somewhere among these unused pins that there just had to be the signals to drive a VGA monitor.
I guess that I wasn't the only one. Someone going by the handle ymboc over on MediaSmartServer.net not only had the same hunch, but took his suspicion a to the next level. ymboc has not only determined that CN2 contains signals for R, G and B video output, but also HSYNC and VSYNC. He has also ordered the proper connector and has tinkered with actually connecting a monitor! So far he hasn't produced any visible VGA output, but I'm guessing that he should have it solved within days at the rate he is going.
I'll be building my own cable as soon as he has everything worked out and will be happy to provide complete instructions here (or link to ymboc's instuctions if they are made available).
Great job ymboc! You deserve a lot of credit for the work you have done so far and I look forward to seeing your completed project. You can follow ymboc's progress and read all of the excitement here.
**** UPDATE ****
He did it! Watch the YouTube video showing a VGA monitor hooked up to the HP EX470 motherboard.
**** UPDATE 2 ****
As ymboc points out in the comments, a complete schematic of CN2 has been posted along with pin outs for a serial port and PS2 keyboard and mouse (although it is labeled CN9 for some reason). Thanks for the heads up.

Now that is cool!
Hello, I am not sure if you guys have any viewers that can write drivers and such or any information but I own a ex470 and a gaming rig, xp 64-bit machine,
I have been able to get the connector running on 64-bit xp and I am able to get it to back up fully.
Problem is when I go to open a backup that completed off of the 64-bit xp machine it goes to 6% then wants me to install a driver for the "possible - restore" - Driver is dually noted as "Windows Home Server Restore Driver 2".
Great... almost there.
I hit ok to the install of the driver and then the opening of the 6% open backup immediately fails.
I've looked into the issue, found it to be attempting to load VolSnap.inf driver.
VolSnap is part of Vssvc.exe which is volume shadow copy service.
If we can get some good people to develop something or build volsnap (x64) into a re-built from ground up, or simply a restore only connector we could have the ex470/ex475 running for x64.
Let me know what you think.
Thanks.
Just a heads-up. JRock over on the MediaSmart forums has posted the complete pin-out for the VGA Connector header, adding serial & PS2 as well.
@ymboc - I saw that and have been meaning to post the image and reference here for me readers (I'll do that now). Allow me to personally congratulate you for your hard work! The schematic will definitely help, but it was your effort that made the difference.
Thanks for the kind words. I think "CN9" refers to the connector on the break-out board pictured in the thread - fortunately the pinout matches CN2.
Awesome!
Now for the question to the answer.
Using this technique to gain access to the BIOS, can a SATA mirror be created so that the OS disk is hardware protected against failure?
Well . . . not to answer my own question . . . but I have found a way to set the ex470 up with SATA RAID (JBOD,0,1) without using the BIOS.
I would be happy to start a new thread if anyone else is interested.
This gets away from the current data corruption issue with WHS as you can set all your disks up as one big drive.
Wouldn't that work against what WHS does? It's not meant for that, is it?
You can also buy a cable if you do not feel like going through the trouble in building one. Details are here:

W..w...wait. If there's no VGA port except for the one you mentioned (which could, if i understood the article, only be used if you removed the case) then how would you connect a monitor to the EX470?!
The posting to buy the cable has been removed. Any ideas where one can be bought?
@Don - The posting to buy a cable was never removed. The service was temporarily suspended until the gen2 cables were released.
