I tried the pcisetup program tonight in the hope of getting the 
DB25-1205 breakout board inputs working on my CNC router with the D525MW 
motherboard.  No luck.  I did the dmesg stuff and it reported the same 
parallel port location as the example posted recently to this email 
list.  The program compiled OK with a warning about redefining the exit 
function or something like that, and it ran OK with a message about 
writing some value to some memory location, but the inputs that I 
monitored in LinuxCNC remained inactive regardless of whether I applied 
0V or 5V.

I'm fairly sure I configured the BIOS to set the parallel port to EPP.  
I was unable to get into the BIOS setup tonight.  Apparently, I need a 
wired keyboard, because presumably the BIOS ignores the Logitech K400 
wireless keyboard until after it scans for a keyboard F2 to enter the 
BIOS setup.  It's the wireless keyboard catch 22. I'll take a wired 
keyboard tomorrow to access the BIOS and double check the BIOS setup.

As much as I appreciate Jon's pcisetup code, this seems like a BIOS bug 
to me, and if I can flash the BIOS and fix it (or brick it!) then I'd 
prefer to do that.  My brain is too old to remember to do the pcisetup 
trick again if I ever change the motherboard, SSD, reinstall 
Ubuntu/LinuxCNC, etc.  I have one other D525MW motherboard for the 
imminent mini lathe conversion, so I hope to flash the BIOS on both of 
them at the same time.

It's been a long week and my geek mojo was weak tonight.  I ended up 
abandoning the 90 degree shop to sit in the air conditioning and 
research CAM programs.  Looks like I'll be installing MeshCAM under Wine 
tomorrow, assuming I get my mojo back.  I don't expect that to need much 
geek mojo.

Slow, mostly steady progress on my Summer Of Projects.
