Well, nuts. Here it is, a rainy Saturday afternoon, and I thought I'd just zip out to the Internet and gather some info about these SIIG products. Reason: I want to buy myself a couple "new" parallel port adapters (I've down to a few several that are truly ancient) and SIIG boards seem abundant. If I already had one like yours I'd be playing with it instead of the Internet. On the SIIG website, I found no technical data worth spit but I did find the Windows driver zip file for your product and download it. From its inf files, it's clear to me that the chip may be marked SIIG CyberPro but it's actually designed by Oxford Semiconductor and fab'bed who knows where. So I go to the Oxford site for some technical data. Or not. It turns out that Oxford Semiconductor was purchased by PLX Technology several years ago. PLX Tech has hidden all its techical data, app notes, etc., behind a membership-only wall. OK, so I register myself as the Chief Factotum of the Blue Skies Division of the Self-employed Company (this nonsense was required by PLX Tech's nonsensical registration process). Now I'm rummaging through PLX Tech's Apache Server. Too strange to believe, it's oriented toward PLX Tech's hot new products, not the old Oxford Semi stuff, but fortunately old app notes are still to be found if you're sufficiently determined. So far, what I'm finding is either too low level, for example, reference schematics, BOMs, etc., of too high level, for example, how it all works fine with Windows. I did find an app note that describes the testing (I presume by Oxford Semi, not PLX Tech) done to verify parallel port operation, including mode setting. It says "[T]he standard Windows parallel port driver was used, plus a modified debug driver allowing visibility of operation and selection of IEEE 1284 modes." I'll keep digging. A thought: Have you tried running the SIIG card with a recent version of Windows to see if the standard drivers and user interfaces work. If so, then I can't believe there's much of a trick to setting the card with Linux, even if the trick isn't obvious. Another thought: Any reason this conversation can't be moved over to emc-users?
