PCI and PCI-E add on cards with parallel port that work out of the box

The asm1083 is a PCIe to PCI bridge. The other chip would be the chip with the parallel etc functions.
Photos are ok, but the real bit of important info is the PCI ID number.

If you look at the text file I attached a couple of posts ago as well as having info regarding the parallel port cards it also has a couple of commands as where to get the info from the file system. Like what mode the card supports and stuff like that.

That's a great idea! Much more meaningful info than a screenshot.

I think we can make your file format a tempate for this topic. I will update my posts to match your idea.

By the way, how have you managed to setup these wch chipsets to work? It there some special trick? I have never been able to make them work.

Pretty sure I've had the PCIe working.
The PCI one I've used with a Xilinx Parallel Port Programmer, very slow as it really needs EPP or better.

When you say you can't get the WCH to work, do you mean no signals at the pins ?

I might be able to do a quick test just with the Parallel Port tester with a breakout board connected.

I believe the last time I've tried one wch card, the i/o pins were disabled.

But just now I am reading how to use setpci to enable them:

tldp.org/HOWTO/Serial-HOWTO-8.html#pci_enabled
wiki.osdev.org/PCI#Command_Register

I had no idea what those flags from lspci -vv mean. Now I am starting to figure it out.

I'll give it a try. I still have some wch cards. Maybe now I can make them work (knowing what I am doing)
