I found an old (WAY old, 1997) post from Alan Cox talking about how the vendor-provided binary drivers suck, and are distributed poorly: http://www.geocrawler.com/archives/3/59/1997/1/0/2206254/ The current release of the drivers claims to have been tested against 4.2.21, and appear to work with the current release of 2.4 (tried with 2.4.25-rc1). Full source is provided, and there's no mention of a license in any of the files or included documentation. There's a copywright header on the source files, but that's it. The source itself sets MODULE_LICENSE("GPL"), so I'm going to assume they meant it. Here's a link: http://www.equinox.com/Driver_Search_Results153.cfm?uid=331 Has anyone ever tried to add support for this device to the kernel, via the 'non-standard serial port' section? I don't see any options for it in 2.5 or 2.6, and the driver certainly won't compile against either tree. As I understand it, this board does some odd tricks with memory mapping to accelerate transfers: ftp://gsyprf10.external.hp.com/pub/equinox/eqnx_sst-8p.pdf I've never really mucked about much with kernel drivers, but I'm passable in C, and have browsed through O'Reilly's 'Linux Device Drivers'. Is porting a 2.4 driver to 2.6 something that can be worked through with sweat, tears, and some RTFMing, or should I just give up and leave my server in 2.4 in the hopes that Equinox will release 2.6 drivers for this EOL'd card? -Brad
