Peter,
That is good news, at least as far as finding a problem and having a
probable solution. What do I need to do from here? Please feel free to
contact me off list.
BTW, regarding the EMC 2.3.7 + 7i43... thread, I also have a box with a VIA
mini-ITX motherboard
(http://www.mini-box.com/Hybrid-
Well I got one of those MiniITX D945GCLF2 Motherboards and did some testing
The SMSC super I/O chip has very fast edges, and triggers a problem I'd
noticed with one of my plug-in PCI parallel port cards.

With my EPP loopback test and the current firmware I got verify errors

At this point I am just working out the configuration. I am not connected to
anything as far as hardware. There is nothing connected to the P3 and P4
connectors.

Well thats fairly weird. If there is no configuration difference, Is it
possible that there is a electrical nois

Peter,
I found something interesting while checking to get your answers. Presiously
I was only jogging X and Y, and did not get any errors. This time I tried Z
as well. When I jog the Z axis I get the TRAM write error. That would
explain why I get the error when running a G-Code program, but not

The available parallel port modes in the BIOS are Output only,
Bi-directional, EPP and ECP. It is set to EPP, but I do not see a further

Sebastian, et al,
I am getting a strange error using the hostmot2 driver and the 7i43 board.
The error is "hm2/hm2_7i43.0: TRAM write error! (addr=0x1000, size=8,
iter=68373). The error occurs when running a g-code program but not while
jogging, at least initially.
