D510MO

My guess is that if the CD works on both ports and after repeated boots that the issue is with the hard drive.

Sounds logical, I'll try to pick up another drive on the way home

BigJohnT, way to go good diagnosis!

I replaced the Solid State Drive and it worked

I also found some other people had a similar problem with that drive.

Now onward and upward to HAL and Wiring.

Thanks everyone for you help on that, it can be very nerve racking when something that you expect to take minutes to do seems impossible.

I have been following this thread and decided to try out one of these boards.
I got the intel 4GB internal usb flash drive.
I was having problems getting it to boot after installation.
I found that the BIOS needed to be updated (board had vers. 0400, current vers. 542)

Lesson learned: Don;t assume that a new part has all of the latest patches for proper operation!

I hope this is an aid to others thinking of trying this motherboard.

Go to the Intel site www.intel.com
select support from the menu
select "Desktop boards, Intel NM10 chipset family boards, Intel D510MO

that should get you to the downloads page for this motherboard.
select the BIOS downloads. that will show three options. I downloaded the zip file.
On that page you can select the release notes to look through what has been fixed since version 0400

I made a DOS bootable USB stick then unziped the files to that (move the files to the root directory of the USB)
Boot from the stick, then run the iflash2 utility: iflash2 /p MO0542p.bio

It takes about a minute to run. DO NOT POWER DOWN WHILE UPDATE IS IN PROGRESS the system will reboot a couple of times during the process.

This update fixed three issues I was having with installing and running from USB media, plus the system seems more stable.

Got the chance to get a D510MO for a bargain and since my old IBM ThinkCentre doesn't have the best latency times, I thought it's time for a change. Unfortunately I have some strange realtime problems with the board and can't find the reason.

Worst case max jitter is up to 8000ns when I connect USB devices like a stick. My TripleBeast controller runs with the following values:
Step time: 2000ns
Step space: 2000ns
Dir. hold: 2000ns
Dir. setup: 2000ns

I thought I'd be on the very safe side with a base period of 20000 but while testing today I've got a few times the message "Unexpected realtime delay; check dmesg for details". Also it happened a few times that there was only a black screen with the cursor left, when I closed Axis. In some cases I was able to properly shut down the computer by power switch, in other cases the system freezed completely. I increased the base period now up to 35000 but the problem remains.

My system:
- PCI LPT card with Moschip MCS9865
- 160GB WD 2.5" HDD
- 2GB Ram
- PS/2 industrial keyboard with trackball
- Logitech game controller
- fresh Ubuntu 10.04 installation from a live cd, with all recommended updates

Any ideas what to do? I let the latency test run 2 times over night but there are no spikes at all.

Unexpected realtime delay; check dmesg for details

What was in dmesg?

Run linuxcnc until you get the message, close it and immediately copy /var/logs/dmesg somewhere else and zip it and attach.
