[Emc-developers] PCIe EPP parport issues

[Jon Elson]

I have been selling Syba SD-PEX10005 PCIe parallel port 
cards for several years, they seem to work well with most 
computers and LinuxCNC and my line of motion interfaces.  
Now, I have 2 Dell Optiplex 7010 computers that they do NOT 
work on.  It seems that both my diagnostic program and the 
hal_ppmc driver don't talk to it correctly.  These cards use 
the MOSCHIP MCS9900 or MCS9901 chip.  I have one remaining 
Siig card that uses the Oxford Semi chip and it works.  I 
thought I had this EPP weirdness pretty much solved, but now 
I'm up the creek without a paddle again.  Does anybody know 
anything about these PCIe-EPP issues?

Thanks in advance for any help!
Jon
