Could anybody take a look at his picture and see if they can 
suggest what is happening here?  Here's the URL:

Clearly, index-enable is getting shut off before the index pulse 
comes true.  I cannot see how the hardware or driver, as it is 
now written, can do this.

Re: [Emc-users] Multi I/O Driver support - kernel patch

loadrt probe_parport

The 0x20a0 here comes from the manual and mine is different
and is what I got from 'lspci -v'. Also using a PCI parport with
Sunix chip.

Re: [Emc-users] estop writes to toolchange pin out?

I tested with emc 2.1.4, configs/sim/axis.ini, using halscope to trigger
on rising or falling edges of iocontrol.0.tool-change and found the
following:
 * If iocontrol.0.tool-change is FALSE, then going from MACHINE ON to
   ESTOP with the button on the AXIS GUI does not alter
   iocontrol.0.tool-change

 * If iocontrol.0.tool-change is TRUE, then going from MACHINE ON
   to ESTOP with the button on the AXIS GUI sets iocontrol.0.tool-change
   to FALSE.

Is this the behavior you saw?  I am pretty sure it's a deliberate
behavior, and I don't see why it would be problematic.  If you ESTOP in
the middle of a tool change, it's entirely possible that after fixing
the problem it doesn't make sense to continue the tool change operation
(and there's no point anyhow, since the subsequent gcode instruction
won't be executed either).

Re: [Emc-users] Multi I/O Driver support - kernel patch

[Jeff Epler]

emc does not use the linux kernel's parallel port driver, so patching
the kernel for your PCI parallel card won't work and won't change
anything.

Here is the experience of one user with a "NetMos" chipset PCI parallel
card:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos
after finding the address with 'lspci', that address is simply given to
'loadrt hal_parport'.

Jeff
PS to get the source for the exact kernel you're running, 2.6.15-magma,
use apt or an apt front-end to install the package
"linux-source-2.6.15-magma" -- but as I said I don't think that patching
the kernel is going to make any difference here

Re: [Emc-users] How to

[Rod Welland]

Thank s Guys for the response sorry Im a bit late repying but I work a 12hr 
day and night shift pattern and when on shift the PC doesnt go on.

I did now about the Bios and boot order, in fact the pc in my shed boots 
first from A:\ then CD then H/D this is because I still boot to DOS some 
times from a floppy.
In this respect what I was'nt sure of was how the disc or partition was 
formated to except Linux but from your replies this is obviously done when 
you boot from the LiveCD.

I think you hit it on the head Ray Nero has not created a boot disc there is 
only one file on the CD and not the 9 or so I should be seeing. So I,m going 
to download another CD burning prog form the internet today and have another 
go.

All my previous CNC progs are DOS based. The one I use most is TurboCNC, 
current Ver. 4.01 which is a great prog and has a good user forum. But its 
been a while since it was updated probably due to lack of  time avaliable 
from Dave's real time job. But hey we all have to earn a living and I can 
only extend my thanks to him for giving us a great program. Although I'm 
sure I'll continue to use TurboCNC I think its time to look at something 
else and from the response I've had from my first quiery on EMC2 from you 
guy's I think this is a great start as I,m sure to run into a few more 
problems.

Thanks Rod
