(This is on a 5.2.1 laptop, but I've ported small parts like ndis and pccarddevs from -current back to my src tree) I recently bought a DWL-650 revP 802.11b wireless pcmcia card with the expectation that it would work with FreeBSD. Early revisions of that card apparently do, but not revP. I think this is a somewhat known problem, but I'm trying to help document my troubles so maybe someday we'll have it working. :) Upon finding out that it does not work, I did some research. Apparently, it uses the PRISM3 chipset, which according to the wi(4) manpage is supported, but I do not see any cards listed with it there. DWL-650 -is- listed there, but only applies to earlier versions of the card (not revP) Anyhow, an earlier thread on -current_at_ mentioned making some changes so that wi(4) would know about this card from the wild, but for the person involved it did not work with the message that the busy bit would not clear. It fails for me in the same way. Supposedly this is because the firmware is not loaded, and there are certain tools available for windows and linux which will load it. I tried the card with a win2k laptop, and it worked fine (firmware was 1.8.0 I think). Brought it back to FreeBSD, and the card still did not work. Tried ndis, that didn't work either (more on that later). Apparently, from what I understand from my googling, it is the responsibility of the driver to load the firmware at startup because the chip lacks the ROM to hold it (so it has to be loaded into card's RAM instead?). (Hmm... Apparently this is called Short Serial Flash) About my attempts to make it work with ndis: it simply did not work. At first, ndiscvt had trouble with the .inf file. There was no newline at the end of file, but once I added one it was fine. Managed to compile the modules fine, tried to run it, and nope, still doesn't work. The wi(4) driver would continue to try to grab it, so I compiled wi out. Nope...ndis did not appear to match itself with the card at all. In the end I ended up erasing the card entirely (I think...somehow?). Oops. It doesn't work with the windows laptop anymore. However, windows keeps pulling the driver out of somewhere, so I haven't been able to get it to deinstall/reinstall properly so I can possibly hopefully make the card work again. Interestingly enough, FreeBSD complains about the busy bit no matter if it happens to work in windows or not. For reference, wi(4) displays this: wi0: <D-Link DWL-650 Wireless PC Card RevP> at port 0x400-0x47f irq 11 function 0 config 1 on pccard1 wi0: wi_cmd: busy bit won't clear. : init failed device_probe_and_attach: wi0 attach returned 6 -- Robin Schoonover (aka End) # # "Did you know that black paint is an excellent stain remover?" # - DogbertReceived on Thu Aug 12 2004 - 00:13:12 UTC
