VGA/PS2 build project for EX470/75/85/87/90/95 & H340 home servers.

Hi ya folks,

I’m looking at starting a project on building a VGA/PS2 interface for the HP MediaSmart and the Acer H340 EasyStore servers.

HP has come out with their 3rd generation home servers, the EX49x and I know Microsoft prefers WHS boxes to be headless. But with the recent changes to the EX49x boxes, reinstalling the server software has become more difficult and is a shot in the dark process.

So I figured I’ll try and build a printed circuit board to make this process more bearable.

What’s nice is that the Acer home server are built using the same internal connector, so this PCB will work on those boxes also.

Parts List from Digikey ;

PHDR-26VS999-H15-PS2-571B26B-PHDSSWe Photo

CONN HOUSING PHD 26POS 2MM DUAL , CONN HD15 FEMALE OVER DUAL PS/2

CONN HEADER PHD TOP 26POS 2MM, CONN TERM PHD CRIMP 22-26AWG TIN

Printed Circuit Board Software ;

I’ll be using ExpressPCB to design the printed circuit board. You can find the software here ; http://www.expresspcb.com/ExpressPCBHtm/Free_cad_software.htm

I plan on making the PCB parts template and PCB design available for '>download. So anyone can tweak it for themselves. I have to purchase a minimum number of PCB’s to place an order so I’ll end up with extras.

Next I will have to build a cable to connect the two. I’m hoping to find a straight thru design. I’ll update this blog post as things develop.

Join me in the forums where we can discuss it .

How to create an external bootable USB Server Recovery Thumb Drive for a easier Server Recovery of your EX490/5

usb-stick-copy-300x196
Ok, so you love your EX470/5 but you want to move on to the new EX490/5, it’s time. Everything has been improved, right, WRONG.
The HP EX490/5 so far has been HP’s best home servers yet. However I find that removing the internal 256 MB flash is a mistake. Now you must have a direct connection between your server and the PC that will run the Server Recovery DVD. You also have to turn off your firewall and anti-virus software. Then you must have the correct timing to press the reset pin. All this without a VGA connection on your server. So your doing this in the dark. I’m not happy about that because it was easier on the EX470/5 and I was spoiled. I want it back.
If you have a EX470/5 and a EX490/5 then you already have most of what you need.
So I’ll show how to create a bootable USB thumb drive to use on your EX490/5 so that you can restore your server pretty much just like it’s done on the EX470/5.
The software you will need can be found on the EX470 hidden flash, the EX470/5 Server Recovery Disk, the EX490/5 Server Recovery Disk and the EX490/5 network drivers from Realtek’s website.
First off, not all USB thumb drives are equal. This is important to know because you might have done everything right and it still doesn’t work. So you will have to test the thumb drive, more on this later.
I tried this on a Gizmo Jr. 2 GB stick, but you can start with a 256MB stick, use whatever costs less. For simplicity, follow this link to format the thumb drive. Thanks Donavon.
Next, you need the boot software from the hidden partition on the EX470/5. Since it’s a hidden partition you need to unhide it. RDC into your EX470, right click My Computer, properties, hardware, device manager, open up System devices, disable the MediaSmart Server device, reboot. Thanks Teknmage. After the reboot RDC back in. Now open My Computer you should see the hidden partition and copy those file to your PC where you will work with them. Now go back and enable that MediaSmart Server device.
The folder should look like this;
USB flash
 Next, since the EX490/5 has a different NIC card, you need the drivers from Realtek. Choose WinXP and WinServer 2003 Driver. 5.742 Replace the drivers in the \drivers folder with the new ones.
Next, open up the SOURCES folder and replace the boot.wim file with the boot.wim file from your EX490/5 Server Restore DVD. It is in the \PXE\Boot folder. The size should be 120,038 KB.
Now your external USB Bootable Server Recovery Thumb Drive is ready. Test it on your PC and boot from it to see if the Server recovery software starts, if it does, shut down your PC and remove it. Now you know it boots. BSRTD
Now for the PC side;
If you use the EX490/5 Server Recovery DVD as is, it will try and run the PXE boot stuff. We don’t want that. What you need to do is create a DVD using the EX470/5 DVD boot stuff but replace the server image in “\Recovery Image\volume.image” with the server image from the EX490/5 DVD.  You can also replace the Home Server Connector Software with the one from the EX490/5 Software Installation Disk.
This is the EX470/5 Server Recovery Disk. Copy this disk to your desktop, then replace the Recovery Image folder with the same folder from the EX490/5 Disk. Then burn a new Disk.
EX470 boot DVD
That’s it.
Now to recover the server. Power off the server. Install the bootable USB key into the bottom rear USB port. Pull the system drive out 1 inch so that it does not make contact with the rear back plate. ( this is so you don’t have to fiddle with the reset pin). Power on. Wait 5 seconds then push the system drive back in. Run the newly created Server Recovery DVD. It should find the server. Now go ahead and Restore your EX490 while it’s still connected to the network. Server Recoveries will be a lot easier now.
Just so you don’t mess things up, I recommend that you have your server shares backed up. Or pull all your drives out and try it on a spare system drive.
