This is the reply from Sohoware: "Andrea, Due to the very limited information you have provided, we are unsure what you are trying to say. Please provide us with the following information: 1. What OS are you running? 2. What error message are you getting when you are trying to install the card? 3. Where did you buy the card from? Regards, Tech Support " And this is my answer: ----------------------------- > 1. What OS are you running? I'm running FreeBSD 4.7 which supports Prism2/2.5 based cards. The card I have is a NCP130 that should be Prism based.Shouldn't it? >2. What error message are you getting when you are trying to install the card? The message i got is: wi0: No I/O space?! device_probe_and_attach: wi0 attach returned 6 Usually this problem comes out when the PCI card doesn't claim IO space in the resource list,while local registers and attribute memory can both be found. How's this possible? Do you have any clue? Are these informations placed elsewhere? >3. Where did you buy the card from? I bought it from E-Bay, the card was still sealed. > > Regards, ------------------------------ And Finally the obvious Answer :( ------------------------------ Andrea, Yes the NCP130 is has the Prism chipset, but we do not provide drivers or support for Linux user with the CableFREE II series product. Regards, ------------------------------ I tried asking for further informations but without success... So I did further investigations on my own and I found out that the linux driver supports that card! Using the useful informations about PCI programming found in this book http://www.xml.com/ldd/chapter/book/index.html , I managed to modify wi driver to make it recognize the card properly. And ... It works! This is the patch ,I applied it against 5.0-current ,but it should work on different RELEASES , 'cause that part of code didn't get modified trough versions. ---- CUT HERE ---- diff -crN wi/if_wi_pci.c wi.new/if_wi_pci.c *** wi/if_wi_pci.c Wed Jan 15 21:11:31 2003 --- wi.new/if_wi_pci.c Sat Mar 15 18:50:36 2003 *************** *** 101,106 **** --- 101,107 ---- {0x16ab, 0x1102, WI_BUS_PCI_PLX, "Linksys WDT11"}, {0x1385, 0x4100, WI_BUS_PCI_PLX, "Netgear MA301"}, {0x1638, 0x1100, WI_BUS_PCI_PLX, "PRISM2STA WaveLAN"}, + {0x15E8, 0x0131, WI_BUS_PCI_ASIC, "Prism II InstantWave HR PCI card"}, {0x111a, 0x1023, WI_BUS_PCI_PLX, "Siemens SpeedStream"}, {0x16ec, 0x3685, WI_BUS_PCI_PLX, "US Robotics 2415"}, {0, 0, 0, NULL} *************** *** 150,162 **** } if (sc->wi_bus_type != WI_BUS_PCI_NATIVE) { ! error = wi_alloc(dev, WI_PCI_IORES); ! if (error) ! return (error); ! ! /* Make sure interrupts are disabled. */ !

I didn't test it thorougly so it may have some problems with particular configurations. Actually it may have some problems on the init/reset code and it could require some adjustment,but it works for me as it is so... :) Bye.
