I just had a power failure, so I was able to check the ioports listing before anything had talked to the port, and it still shows the extra 37b-37f field. But, then, this is an older CentOS system, not the 10.04 EMC install, so the listing format might be different.
Have you tried the diagnostic program I mentioned earlier? You can also try my program that sets a port to EPP mode, http://pico-systems.com/codes/pcisetup This is pre-compiled, and may not work on a 10.04 kernel, but you can try it. You will need to do : chmod u+x pcisetup to make the file executable, and then run it with sudo as it is directly adjusting system hardware : sudo ./pcisetup 378 But, this likely won't do anything, as this function has been added to the ppmc driver. However, as the port reports no EPP capability (based on the ioports list) it won't actually perform this function in the driver. pcisetup is dumb, and will just force it anyway. Well, I'm guessing this must be a Linux PnP/driver problem where it doesn't recognize this particular parallel port chip and so doesn't understand that it is actually EPP capable. > I am getting the same error messages weather set EPP or ECP, from > the begenning.
