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.
